将用户控件绑定到滚动条WPF

Question

I'm having a UserControl which I'm going to use as a Find/Replace UserControl, like the one in Visual studio.

I'm placing this UserControl on top of a TextBox .

Users are able to zoom in and out in the TextBox , which makes the ScrollBar and text smaller/bigger.

So my question: Is it possible to bind my UserControl to the ScrollBar's width?

(I could of course listen to the zoom event and calculate the width, but I would like an easier and better approach)

Answer 1

也许是这样的吗？

<UserControl Name="uc" Width="{Binding ElementName=scrollBar, Path=ActualWidth}" />

Answer 2

I solved this by: Comparing TextEditor.TextArea.ActualWidth to TextEditor.ActualWidth , every time the ScrollBar became visible and when the user zoomed. The difference was used to updated the margin of my UserControl .
