Unable to drag RadExpander by its header

[Ken]

I have a RadExpander containing an ItemsControl with a group of objects I need to drag/drop.  I find that I am able to drag the expander only by its non-header parts.  Thus when it is collapsed I can never drag it.

I figured this is due to mouse capture by the expander's button.  Using techniques from another post, I disable the button and find that I can then drag it.  Unfortunately, I find I cannot do this 'on the fly' (i.e., when I first get the drag query) as the button has apparently already captured.

Do you have any suggestions on how I can achieve dragging the expander by its header?

Hi Ken,

Thank you for your interest in the RadExpander control.

The reason of non-draggable header is the placement of the toggle button - within themes we had released this button occupied the whole header's surface - this way the expander will toggle regardless where you click, but the button interferes with the control's drag-ability.

In order to modify your expander-object to behave a draggable one, you should edit its template - shrink the button and leave enough space for dragging. Please note there is a solution with all five theme projects in our release - all style, templates, brushes, etc. are their Generic.Xaml files - just copy and modify what you need.

We hope this information will help you.

All the best,
Ivan
