Hello, Ahmed,
Please excuse me for the misunderstanding but it was not clear enough according to the provided information.
RadTextBox/
RadTextBoxControl are input controls. They can't be added to the non-client area of the form which is the title bar. The focus won't be passed to the text box. The possible solution that I can suggest is to use a
ShapedForm with a
RadTitleBar. Then, add a
RadTextBox/
RadTextBoxControl to the
RadTitleBar at design time.
I hope this information helps. If you have any additional questions, please let me know.
Regards,
Dess
