not possible to listen to events

[Tobias Koller]

I followed your example on 

     https://ej2.syncfusion.com/blazor/documentation/diagram/native-events/

to set events to the diagram.

It was not possible:

1. your example-cdoe uses UIMouseEventArgs which are now MouseEventArgs

2. When I try exactly the example I get the following error:

System.AggregateException: One or more errors occurred. (InvalidCharacterError: Failed to execute 'setAttribute' on 'Element': '@onmousedown' is not a valid attribute name.)

 ---> System.InvalidOperationException: InvalidCharacterError: Failed to execute 'setAttribute' on 'Element': '@onmousedown' is not a valid attribute name.

   at Microsoft.AspNetCore.Components.RenderTree.Renderer.InvokeRenderCompletedCallsAfterUpdateDisplayTask(Task updateDisplayTask, Int32[] updatedComponents)

   --- End of inner exception stack trace ---

Is there a way to disable label-edit-functionallity on double-click of node?

Hi Tobias, 

 

Please set AnnotationConstraints as ReadOnly to disable the editing of label at runtime. Please refer to a code example, help documentation and the sample below. 

 

Code example: 

   DiagramNode node1 = new DiagramNode() 

        { 

            // Position of the node 

            OffsetX = 250, 

            OffsetY = 250, 

            // Size of the node 

            Width = 100, 

            Height = 100, 

            Annotations = new ObservableCollection<DiagramNodeAnnotation>() 

            { 

                new DiagramNodeAnnotation() 

                { 

                    Content = "Node", 

                    Constraints = AnnotationConstraints.ReadOnly 

                } 

            }, 

            Style = new NodeShapeStyle() { Fill = "#6BA5D7", StrokeColor = "white" } 

        };
