Some WPF controls such as
PopUps,
ComboBoxes or
ToolTips are always on top of the WPF layer.
WPF.TextControl implements the same approach - a separate independent Window is required to provide the true WYSIWYG rendering.
But
due to the fact that WPF.TextControl uses a similar approach, you can
use the same work-around to draw other controls on top of these
controls. The above mentioned elements including TextControl have their
own Window which is always displayed on top of other controls. To render
a control on top of these controls, you need to encapsulate them in
their own Window.
The following code shows how to create and
display a Window on top of WPF.TextControl. The container Window itself
can have any kind of WPF children:
TextWindow testWindow = new TextWindow();
testWindow.Width = 200;
testWindow.Height = 200;
testWindow.Owner = Window.GetWindow(this);
testWindow.ShowInTaskbar = false;
testWindow.WindowStyle= WindowStyle.None;
testWindow.AllowsTransparency = true;
testWindow.Background = Brushes.Transparent;
Point relativePoint = textControl1.TransformToAncestor(this).Transform(
new System.Windows.Point(0, 0));
testWindow.Left = relativePoint.X + this.Left;
testWindow.Top = relativePoint.Y + this.Top + 50;
testWindow.Show();
