Button Click Event Getting Lost
- by AlishahNovin
I have a Menu and Submenu structure in Silverlight, and I want the submenu to disappear when the parent menu item loses focus - standard Menu behavior. I've noticed that the submenu's click events are lost when a submenu item is clicked, because the parent menu item loses focus and the submenu disappears.
It's easier to explain with code:
ParentMenuBtn.Click += delegate
{
SubMenu.Visibility = (SubMenu.Visibility == Visibility.Visible) ? SubMenu.Collapsed : SubMenu.Visible;
};
ParentMenuBtn.LostFocus += delegate
{
SubMenu.Visibility = Visibility.Collapsed;
};
SubMenuBtn.Click += delegate
{
throw new Exception("This will never be thrown.");
};
In my example, when SubMenuBtn is clicked, the first event that triggers is ParentMenuBtn.LostFocus(), which hides the container of SubMenuBtn. Once the container's visibility collapses, the Click event is never triggered.
I'd rather avoid having to hide the sub-menu each time, but I'm a little surprised that the Click event is never triggered as a result...
Anyone have any thoughts about this?
