## Drag and drop audio insertion
197+
198+
By default, the Rich Text Editor allows you to insert audios by drag-and-drop from the local file system such as Windows Explorer into the content editor area. And, you can upload the audios to the server before inserting into the editor by configuring the saveUrl property.

### Disabling audio drag and drop
209+
210+
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.
211+
212+
```
213+
<RichTextEditorEvents OnMediaDrop="@OnMediaDrop"></RichTextEditorEvents>
214+
@code{
215+
private void OnMediaDrop(MediaDropEventArgs args)
216+
{
217+
if (args.MediaType == "Audio") {
218+
args.Cancel = true;
219+
}
220+
}
221+

## Rename audio before inserting
197224

198225
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
219247

220248
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.
