Hi Piyush Patel,

This is expected bahvior, the controls in the tab content loose their state when the tabs are changed, because the content is re-created every time from the framework. You should handle the tab selection change and to restore the previous state of the expander control.

Hi Piyush Patel,

Yes - the expander control has expanded and not expanded state. You need to handle the Expanded event and to store in a private variable if the expander is open or closed. When the tab selection changes you need to update the expander state. If it was open set the IsExpanded to true, otherwise set it to false.

Hope this make it clear now.

Hi Piyush,

Thank you for your interest in the RadExpander control.

The observed behavior is the correct one according to the current implementation of the RadExpander control. Please note the Arrow sign points the direction where the expander's content will move if the animation is enabled. For example when the Expand Direction is Down (this is the default value) the arrow will point:

• Down when expander is collapsed (IsExpanded = False);
• Up when expander is expanded (IsExpanded = True);

Please preview the attached example where a form with four expanders is implemented as a visual aid.

We hope this information will help you.

Best wishes,
Ivan
