Hello, Haris,
Thank you for writing.
The
TextTool allows you to enter the edit mode of a
RadDiagramItem as soon as you click on it. Furthermore, you can use this tool to draw text shapes. As it isn't active by default, you can use the RadDiagram.
ActiveTool property to activate it.
I hope this information helps. Should you have further questions I would be glad to help.
Regards,
Dess
