Disable the ability for UltraExplorerBarGroups to expand/collapse?
posted

I'm using the Groups in my UltraExplorerBar as a navigation element.  (forms are loaded when the user clicks on a group)...

 

I would like to disable whatever it is in the control that expands/collapses the panel when the user clicks on the header.

Is this possible?  Thank you very much in advance.

    One solution would be to handle GroupExpanding/GroupCollapsing, use the UltraExplorerBar.UIElement.ElementFromPoint method to hit test for the ExpansionIndicatorUIElement, and cancel the event if the hit test does not yield one:

    void explorerBar_GroupExpanding(object sender, CancelableGroupEventArgs e)
    {
        UltraExplorerBar explorerBar = sender as UltraExplorerBar;
        bool expand = false;
        Point point = explorerBar.PointToClient(Control.MousePosition);
        UIElement element = explorerBar.UIElement.ElementFromPoint( point );

        while ( element != null )
        {
            if ( element is ExpansionButtonUIElement )
            {
                expand = true;
                break;
            }
           
            element = element.Parent;
        }

        e.Cancel = ! expand;
    }
