When a RadTextBox has text in it, a "X" is rendered at the right side of the textbox that clears out the text in the textbox when clicked. Is there a ClientEvent for clicking on the "X"? I'd like to disable a button when the "X" is clicked.
As far as my knowledge RadTextBox doesn't have any Button inside the TextArea. In order to achieve your scenario you have to add an external button inside the TextBox as follows.
