i implement Radtoolbar with basic functions but only copy undo and cut commands are working . the others editingcommans and applicationcommand arn't working sush as EditingCommands.DecreaseFontSize or increase
could you give me an example to implement it.
thanks by advance
Your issue is caused by the fact that the native TextBox control does not support formatting-related editing commands like these defined in the EditingCommands class. In order to use these commands you can try to replace the TextBox with a RichTextBox. For more information about the supported commands you can read this article. Please take a look at the attached project and let me know if it solves your issue.
