+
+# Collaborative Editing in Blazor Diagram
+Collaborative editing in the Syncfusion Blazor Diagram Component allows multiple users to work on the same diagram simultaneously. All changes are synchronized in real time, so collaborators instantly see updates as they occur. This feature improves productivity and teamwork by eliminating delays.
+
+To achieve this, the system uses:
+
+* `SignalR` for real-time communication between Blazor application and the ASP.NET Core SignalR Hub.
+* `Redis` as a temporary data store and backplane for scaling across multiple servers.
+
+## Prerequisites
+The following are required to enable collaborative editing in Diagram Component:
+* Add the following NuGet packages:
+    * Blazor Application:
+      * Microsoft.AspNetCore.SignalR.Client
+      * Syncfusion.Blazor.Diagram
+    * ASP.NET Core SignalR Hub:
+      * Microsoft.AspNetCore.SignalR
+      * Microsoft.AspNetCore.SignalR.StackExchangeRedis
+      * StackExchange.Redis
+
+## How It Works
+  1. SignalR Connection
+     * SignalR enables real-time communication between the Blazor application and the server hub. Each user joins a SignalR group (room) for a specific diagram session. Updates are broadcast only to users in the same room.
+
+  2. Using Redis for Conflict Resolution
+      * Redis ensures that collaborative editing works in a distributed environment by:
+         * Storing versioning data for conflict resolution.
+         * Periodically cleaning old version data to prevent memory issues.
+
+## Cleanup strategy for Redis
+
+To prevent unbounded memory growth and maintain stable performance, implement one or both of the following:
+* Keep only the last K versions
+    * Maintain a fixed-size history (e.g., the last 200 updates) and trim older entries after each push.
+    * Retains only recent updates needed for conflict checks and recovery.
+* Apply TTL (Time-to-Live) to keys
+    * Set expiration on Redis keys that store version and history data.
+    * Bounds memory usage and automatically cleans up stale sessions.
+```csharp
+// In IRedisService
+Task<bool> SetAsync<T>(string key, T value, TimeSpan? expiry = null);
+// In RedisService
+public async Task<bool> SetAsync<T>(string key, T value, TimeSpan? expiry = null)
+{
+    try
+    {
+        string serializedValue = JsonSerializer.Serialize(value);
+        return await _database.StringSetAsync(key, serializedValue, expiry);
+    }
+    catch (Exception ex)
+    {
+        _logger.LogError(ex, "Error setting key {Key}", key);
+        return false;
+    }
+}
+
+// For example, Applying TTL to the version key
+const string versionKey = "diagram:version";
+long version = 5;
+await _redisService.SetAsync(versionKey, version, TimeSpan.FromHours(1));
+```
+
+## Best Practices for Hosting, Transport, and Serialization in Blazor Collaboration
+
+To ensure reliable and efficient collaborative editing, consider the following best practices:
+* **1. Hosting**
+    * Enable WebSockets on your hosting environment and reverse proxy (e.g., Nginx, IIS, Azure App Service).
+    * Configure keep-alives to maintain long-lived connections and prevent timeouts during idle periods.
+* **2. Transport**
+    * **Preferred:** WebSockets for low-latency, full-duplex communication.
+    * **Fallback:** If WebSockets are unavailable, remove SkipNegotiation on the Blazor application to allow SignalR to fall back to ASP.NET Core SignalR Hub-Sent Events (SSE) or Long Polling.
+* **3. Serialization**
+    * For large payloads, enable MessagePack on both collaboration hub and blazor application projects for efficient binary serialization.
+    * Consider sending diffs (incremental changes) instead of full diagram state to reduce bandwidth usage.

+description: Learn how to implement collaborative editing in the Syncfusion Blazor Diagram component using SignalR and Redis.
+platform: Blazor
+control: Diagram
+documentation: ug
+---
+
+# How to enable collaborative editing in Blazor Application
+
+## Step 1: Configure SignalR HubConnection
+
+* Initialize a SignalR `HubConnection` on the component’s first render (`OnAfterRenderAsync`) and starts it with `StartAsync`.
+* Connects to the `/diagramHub` endpoint via `WebSockets (SkipNegotiation = true)` and enables automatic reconnect to handle transient network issues.
+* Subscribes to the `OnConnectedAsync` SignalR Hub callback to receive the unique connection ID, confirming a successful handshake.
+* After connecting, calls `JoinDiagram(RoomName)` to join a dedicated SignalR group(room) so updates are shared only with users in the same diagram session.
+
+```csharp
+@using Microsoft.AspNetCore.SignalR.Client
+
+@code {
+    private HubConnection? connection;
+    private string roomName = "Syncfusion";
+
+    protected override async Task OnAfterRenderAsync(bool firstRender)
+    {
+        if (firstRender) 
+        { 
+            if (connection == null)
+            {
+                connection = new HubConnectionBuilder()
+                            .WithUrl(NavigationManager.ToAbsoluteUri("/diagramHub"), options =>
+                            {
+                                options.SkipNegotiation = true;
+                                options.Transports = Microsoft.AspNetCore.Http.Connections.HttpTransportType.WebSockets;
+                            })
+                            .WithAutomaticReconnect()
+                            .Build();
+                // Triggered when the connection to the SignalR Hub is successfully established
+                connection.On<string>("OnConnectedAsync", OnConnectedAsync);
+                await connection.StartAsync();
+            }
+        }
+    }
+    private async Task OnConnectedAsync(string connectionId)
+    {
+        if(!string.IsNullOrEmpty(connectionId))
+        {
+            // Join the room after connection is established
+            await connection.SendAsync("JoinDiagram", roomName);
+        }
+    }
+}
+```
+
+>**Notes:**
+>* Use a unique `RoomName` per diagram (e.g., a diagram ID) to isolate sessions.
+>* If `WebSockets` may be unavailable, remove `SkipNegotiation` so SignalR can fall back to SSE or Long Polling.
+>* Consider handling reconnecting/disconnected states in the UI and securing the connection with authentication if required.
+
+## Step 3: Sending and Applying Real-Time Diagram Changes
+
+* Detect changes: The Blazor Diagram component triggers the `HistoryChanged` event whenever the diagram is modified (e.g., add, delete, move, resize, or edit nodes/connectors).
+* Create deltas: Use [GetDiagramUpdates](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.SfDiagramComponent.html#Syncfusion_Blazor_Diagram_SfDiagramComponent_GetDiagramUpdates_Syncfusion_Blazor_Diagram_HistoryChangedEventArgs_) to produce a compact set of incremental updates (JSON-formatted deltas) representing just the changes, not the entire diagram.
+* Broadcast to the room: Send these deltas to the hub method `BroadcastToOtherUsers`, which relays them to all users joined to the same SignalR group (room).
+* Apply remotely: Each remote user listens for ReceiveData and applies the incoming deltas with [SetDiagramUpdatesAsync](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.SfDiagramComponent.html#Syncfusion_Blazor_Diagram_SfDiagramComponent_SetDiagramUpdatesAsync_System_Collections_Generic_List_System_String__), keeping their view synchronized without reloading the full diagram.
+* Group interactions: Enable [EnableGroupActions](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.DiagramHistoryManager.html#Syncfusion_Blazor_Diagram_DiagramHistoryManager_EnableGroupActions) in [DiagramHistoryManager](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.DiagramHistoryManager.html) to treat multi-step edits (like drag/resize sequences or batch changes) as one operation. When enabled, `HistoryChanged` raises [StartGroupAction](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.SfDiagramComponent.html#Syncfusion_Blazor_Diagram_SfDiagramComponent_StartGroupAction) and [EndGroupAction](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.SfDiagramComponent.html#Syncfusion_Blazor_Diagram_SfDiagramComponent_EndGroupAction). Send updates after `EndGroupAction` to reduce network traffic (one consolidated update) and apply changes atomically for all collaborators.
+
+```razor
+<SfDiagramComponent @ref="@DiagramInstance" ID="@DiagramId" HistoryChanged="@OnHistoryChange" >
+    <DiagramHistoryManager EnableGroupActions="true"></DiagramHistoryManager>
+</SfDiagramComponent>
+
+@code {
+    private async Task InitializeSignalR()
+    {
+        if (connection == null)
+        {
+            connection = new HubConnectionBuilder()
+                        .WithUrl(NavigationManager.ToAbsoluteUri("/diagramHub"), options =>
+                        {
+                            options.SkipNegotiation = true;
+                            options.Transports = Microsoft.AspNetCore.Http.Connections.HttpTransportType.WebSockets;
+                        })
+                        .WithAutomaticReconnect()
+                        .Build();
+            // Triggers when connection established to SignalR Hub
+            connection.On<string>("OnConnectedAsync", OnConnectedAsync);
+            // Apply remote changes to current diagram.
+            connection.On<List<string>>("ReceiveData", async (diagramChanges) =>
+            {
+                await DiagramInstance.SetDiagramUpdatesAsync(diagramChanges);
+            });
+            await connection.StartAsync();
+        }
+    }
+    public async void OnHistoryChange(HistoryChangedEventArgs args)
+    {
+        if (args != null)
+        {
+            List<string> parsedData = DiagramInstance.GetDiagramUpdates(args);
+            if (parsedData.Count > 0)
+            {
+                // Send changes to the SignalR Hub for broadcasting
+                await connection.SendAsync("BroadcastToOtherUsers", parsedData, roomName);
+            }
+        }
+    }
+}
+```
+
+## ASP.NET Core Hub configuration
+
+### Step 1: Configure SignalR with Redis and Map the Diagram Hub(Program.cs)
+
+Use the following setup to enable real-time collaboration on a single server instance. This configuration:
+
+* Add your `Redis` connection string to `appsettings.json`.
+```json
+{
+  "Logging": {
+    "LogLevel": {
+      "Default": "Information",
+      "Microsoft.AspNetCore": "Warning",
+      "Microsoft.Hosting.Lifetime": "Information"
+    }
+  },
+  "AllowedHosts": "*",
+  "ConnectionStrings": {
+    "RedisConnectionString": "<<Your Redis connection string>>"
+  }
+}
+```
+* Reuse a single instance across the app to respect Redis connection limits and improve efficiency.
+
+```csharp
+using StackExchange.Redis;
+
+var builder = WebApplication.CreateBuilder(args);
+
+builder.Services.AddSingleton<IConnectionMultiplexer>(sp =>
+{
+    var cs = builder.Configuration.GetConnectionString("RedisConnectionString");
+    return ConnectionMultiplexer.Connect(cs);
+});
+```
+* Configure SignalR to use Redis so group messages are distributed across all app instances.
+
+```csharp
+builder.Services.AddSignalR();
+```
+* Add your Redis-backed service(s) for tasks like versioning, history, or cleanup.
+
+```csharp
+builder.Services.AddScoped<IRedisService, RedisService>(); // your implementation
+```
+
+* Expose the hub at /diagramHub so users can connect with WithUrl("/diagramHub").
+
+```csharp
+var app = builder.Build();
+
+app.MapHub<DiagramHub>("/diagramHub");
+
+app.Run();
+```
+Notes:
+- Ensure WebSockets are enabled on the host/proxy, or remove `SkipNegotiation` on the user to allow fallback transports.
+- Use a singleton `IConnectionMultiplexer` to respect Redis connection limits.
+
+### Step 2: Configure SignalR Hub to Create Rooms for Collaborative Editing Sessions
+Create a folder named `Hubs` and add a file `DiagramHub.cs`. This hub manages SignalR groups (rooms) for each diagram session and broadcasts updates to all participants in the same room.
+
+What this hub does
+* Creates a per-connection session ID and sends it to the user.
+* Allows users join a specific room (diagram session) using a room name/ID.
+* Broadcasts diagram updates to other users in the same room (excluding the sender).
+* Cleans up group membership when users disconnect.
+
+The following key methods are implemented on the collaboration hub:
+* OnConnectedAsync: Invoked when a user connects. Sends the SignalR Hub-generated connection ID to the user for session tracking.
+* JoinDiagram(roomName): Adds the current connection to the specified SignalR group (room) and stores the room mapping for cleanup.
+* BroadcastToOtherUsers(payloads, roomName): Broadcasts updates to all other users in the same room, excluding the sender.
+* OnDisconnectedAsync: Invoked when a user disconnects. Removes the connection from its room(s) to prevent stale memberships.
+
+```csharp
+```csharp
+using Microsoft.AspNetCore.SignalR;
+
+namespace DiagramServerApplication.Hubs
+{
+    public class DiagramHub : Hub
+    {
+        private readonly ILogger<DiagramHub> _logger;
+
+        public DiagramHub(ILogger<DiagramHub> logger)
+        {
+            _logger = logger;
+        }
+
+        // 1) Called when a user connects to the hub
+        public override Task OnConnectedAsync()
+        {
+            // Send a unique connection ID back to the user
+            Clients.Caller.SendAsync("OnConnectedAsync", Context.ConnectionId);
+            return base.OnConnectedAsync();
+        }
+
+        // 2) Adds the current connection to a SignalR group (room)
+        public async Task JoinDiagram(string roomName)
+        {
+            try
+            {
+                string userId = Context.ConnectionId;
+
+                // Store the room name in the connection context for later retrieval (e.g., on disconnect)
+                Context.Items["roomName"] = roomName;
+
+                // Add this connection to the specified group (room)
+                await Groups.AddToGroupAsync(userId, roomName);
+            }
+            catch (Exception ex)
+            {
+                _logger.LogError(ex, "Error joining room {Room}", roomName);
+            }
+        }
+
+        // 3) Broadcasts updates to other users in the same room (excludes the sender)
+        public async Task BroadcastToOtherUsers(List<string> payloads, string roomName)
+        {
+            try
+            {
+                // Send the updates to all other connections in the room
+                await Clients.OthersInGroup(roomName).SendAsync("ReceiveData", payloads);
+            }
+            catch (Exception ex)
+            {
+                _logger.LogError(ex, "Error broadcasting to room {Room}", roomName);
+            }
+        }
+
+        // 4) Removes the connection from its room when the user disconnects
+        public override async Task OnDisconnectedAsync(Exception? exception)
+        {
+            try
+            {
+                // Retrieve previously stored room name
+                string? roomName = Context.Items.TryGetValue("roomName", out var value) ? value as string : null;
+
+                if (!string.IsNullOrEmpty(roomName))
+                {
+                    await Groups.RemoveFromGroupAsync(Context.ConnectionId, roomName);
+                }
+
+                await base.OnDisconnectedAsync(exception);
+            }
+            catch (Exception ex)
+            {
+                _logger.LogError(ex, "Error during disconnect");
+            }
+        }
+    }
+}
+```
+## Conflict policy (optimistic concurrency)
+
+Collaborative edits are managed using version-based optimistic concurrency to prevent conflicts without locking:
+* Versioned updates from the user:
+    * Each change includes the user’s current userVersion, the serialized diagram deltas, and editedElementIds (IDs of nodes/connectors touched by the edit).
+    
+    ```csharp
+    // Capture local changes and send with version + edited IDs
+    public async void OnHistoryChange(HistoryChangedEventArgs args)
+    {
+        if (args == null) return;
+
+        List<string> deltas = DiagramInstance.GetDiagramUpdates(args);
+        if (deltas.Count == 0) return;
+
+        List<string> editedElements = GetEditedElements(args);
+
+        await connection!.SendAsync(
+            "BroadcastToOtherUsers",
+            deltas,
+            userVersion,
+            editedElements,
+            RoomName);
+    }
+    
+    private List<string> GetEditedElements(HistoryChangedEventArgs args)
+    {
+        // Extract and return IDs of affected nodes/connectors from args
+        return new List<string>();
+    }
+    ```
+
+* ASP.NET Core SignalR Hub-side validation (hub + Redis):
+    * The hub compares userVersion with the latest version stored in Redis using a compare-and-increment (CAS) operation.
+    * If versions match, the update is accepted and the version is incremented atomically.
+    * If the user is stale, the hub checks for overlap with recently edited elements:
+        * Stale + overlapping: reject the update, notify the user via ShowConflict.
+        * Stale + no overlap: accept the update and atomically advance the version.
+
+```csharp
+
+using Microsoft.Extensions.Logging;
+using StackExchange.Redis;
+using System.Text.Json;
+public interface IRedisService
+{
+    Task<(bool accepted, long version)> CompareAndIncrementAsync(string key, long expectedVersion);
+}
+
+public class RedisService : IRedisService
+{
+    private readonly IDatabase _database;
+    private readonly ILogger<RedisService> _logger;
+
+    public RedisService(IConnectionMultiplexer redis, ILogger<RedisService> logger)
+    {
+        _database = redis.GetDatabase();
+        _logger = logger;
+    }
+
+    public async Task<(bool accepted, long version)> CompareAndIncrementAsync(string key, long expectedVersion)
+    {
+        const string lua = @"
+            local v = redis.call('GET', KEYS[1])
+            if not v then
+            v = 0
+            else
+            v = tonumber(v) or 0
+            end
+
+            local expected = tonumber(ARGV[1]) or -1
+
+            if v == expected then
+            local newVersion = redis.call('INCR', KEYS[1])
+            return {1, newVersion}
+            else
+            return {0, v}
+            end
+            ";
+        try
+        {
+            RedisResult[] result = (StackExchange.Redis.RedisResult[])await _database.ScriptEvaluateAsync(
+                lua,
+                keys: new StackExchange.Redis.RedisKey[] { key },
+                values: new StackExchange.Redis.RedisValue[] { expectedVersion.ToString() });
+
+            bool accepted = (int)result[0] == 1;
+            long version;
+            if (result[1].Type == StackExchange.Redis.ResultType.Integer)
+                version = (long)result[1];
+            else
+                version = long.Parse((string)result[1]);
+
+            return (accepted, version);
+        }
+        catch (Exception ex)
+        {
+            _logger.LogError(ex, "Error in CompareAndIncrementAsync for key {Key}", key);
+        }
+    }
+}
+```
+
+* Broadcast and user synchronization:
+    * On acceptance, the hub broadcasts the deltas plus the authoritative serverVersion to all other users in the same room (ReceiveData).
+    * Each user applies the deltas via `SetDiagramUpdatesAsync` and updates its local userVersion (either from the ReceiveData payload or via UpdateVersion)
+```csharp

+* The user subscribes to the following SignalR events:
+    * **ShowConflict** to notify users of rejected updates.
+    * **UpdateVersion** to sync userVersion with the SignalR Hub.
+    * **ReceiveData** to apply remote changes and advance to the new serverVersion.
+    * When handling ReceiveData with both payloads and serverVersion, use a handler signature that accepts two parameters (payloads, serverVersion), and pass both to `ApplyRemoteDiagramChanges` so userVersion is updated after applying the deltas.

+## Limitations
+* Default deployment
+    * By default, a single server instance works without additional setup. For multi-instance (scale-out) deployments, configure a `SignalR` backplane (e.g., Redis) and use a shared `Redis` store so all nodes share group messages and version state consistently.
+* View-only interactions
+    * Zoom and pan are local to each user and are not synchronized, so collaborators may view different areas of the diagram.
+* Unsupported synchronized settings
+    * Changes to `PageSettings`, `ContextMenu`, `DiagramHistoryManager`, `SnapSettings`, `Rulers`, `UmlSequenceDiagram`, `Layout`, and `ScrollSettings` are not propagated to other users and apply only locally.
+
+>**Note:** 
+> * Collaboration is supported for actions that raise the `HistoryChanged` event.
