+### Disabling audio drag and drop
+
+You can prevent drag-and-drop action by setting the `OnMediaDrop` argument cancel value to true. The following code shows how to prevent the drag-and-drop.
+
+```
+<RichTextEditorEvents OnMediaDrop="@OnMediaDrop"></RichTextEditorEvents>
+@code{
+    private void OnMediaDrop(MediaDropEventArgs args)
+    {
+        if (args.MediaType == "Audio") {
+            args.Cancel = true;
+        }
+    }
+}
+```
 ## Rename audio before inserting
 
 Using the [RichTextEditorAudioSettings](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.RichTextEditor.RichTextEditorAudioSettings.html) property, specify the server handler to upload the selected audio. Then, by binding the `FileUploadSuccess` event, you will receive the modified file name from the server and update it in the Rich Text Editor's insert audio dialog.

 ## Resize video
 
 The Rich Text Editor has built-in video resizing support, which is enabled for the video elements added. The resize points will appear on each corner of the video when focusing so users can easily resize the video using mouse points or thumb through the resize points. Also, the resize calculation will be done based on the aspect ratio.
