How to Identify Inserted Annotations in Blazor Image Editor?

This article explains how to detect which annotation (shape or text) is inserted into the Blazor Image Editor by using the ShapeChanging event.

When a user inserts a shape or annotation into the Image Editor, the ShapeChanging event is triggered. You can use the event arguments (args.Action) to check if the action is “insert”.

<SfImageEditor @ref="ImageEditor" Height="500">
   <ImageEditorEvents  ShapeChanging="ShapeChanging"></ImageEditorEvents>
</SfImageEditor>

@code {
   
   private void ShapeChanging(ShapeChangeEventArgs args)
   {
       if(args.Action == "insert")
       {
           
       }
   }
}
