    Is dragging and dropping an image into the RichTextBox supported? It doesn't work out-of-the-box and I've always tried the TelerikEditorDemo_WPF example without luck. Scenario: Dragging an image from the desktop and dropping it into the RichTextBox.

    Hello Martin,

    Thank you for contacting us. 

    Image drag-and-drop is not supported out-of-the-box in RichTextBox but you could easily implement it using the Drop event handler. Here is an example implementation: 

    private void radRichTextBox_Drop(object sender, DragEventArgs e)
    {
        string[] droppedFiles = e.Data.GetData(DataFormats.FileDrop) as string[];
     
        foreach (string droppedFile in droppedFiles)
        {      
            using (Stream imageStream = File.OpenRead(droppedFile))
            {
                this.radRichTextBox.InsertImage(imageStream, Path.GetExtension(droppedFile));
            }
                     
        }
    }

    I hope this helps.

    Regards,
