I need to bring to front a custom control in WPF.
pseudoCode
OnMouseDown()
{
if (this.parent != null)
this.parent.BringToFront(this);
}
I know, I know that there are a ZIndex, but still don't understand how to replace the simple WinForm BringToFront to parent.SetZIndex(this, ?MaxZIndex(parent)? + 1) ?
Perhaps there is a better way of doing it in the such a cool thing like WPF?!..
Here is an extension function that adds the method BringToFront functionality to all FrameworkElements that are contained in a Panel.
public static class FrameworkElementExt
{
public static void BringToFront(this FrameworkElement element)
{
if (element == null) return;
Panel parent = element.Parent as Panel;
if (parent == null) return;
var maxZ = parent.Children.OfType<UIElement>()
.Where(x => x != element)
.Select(x => Panel.GetZIndex(x))
.Max();
Panel.SetZIndex(element, maxZ + 1);
}
}
