Hello sri hari,
The behavior you are experiencing is expected as our RadExpander
Header consists of a ToggleButton
and that is how the framework works in that kind of situation. The RadExpander.Header is not expected to put any Buttons
or a TextBox
. You could try use the default controls and the effect will be the same here is a code snippet:
Once pressed the inner button the parent one will be activated after two clicks.
As for a work around you could make custom template for the expander, placing the toggle button and the header content side by side not on top of each other as the default template.
I hope this information works.
