Hi Gong,
Thank you for contacting us on that matter. Please note that the
IsTabStop property of the
RadExpander control is set to
False by default.
However, when you tab into the control, the focus goes in the button inside the header. We designed it like this, because you are allowed to expand/collapse the
RadExpander using the keyboard. When the focus is in the button, you can press the space bar key and the control will change its status.
In order to achieve your requirement, you can extract the default template of the control and manually set the
IsTabStop property of the
RadToggleButton control to
False. Please, have in mind that by following this approach you will not be able to expand/collapse the control using your keyboard.
For your convenience I extracted and edited the default template of the control in the attached project. Please take a look at it and let us know if you need any further assistance.
Regards,
Pavel R. Pavlov
