如何在窗口中查找WPF元素的位置

Question

I need to be able to find the location of a WPF element on an application window so i can then draw a rectangle around the specific element on a screenshot/image capture of the window containing this element.

This is for a VS Coded UI Framework i am developing that has window captures or element capture to an image when an error occurs. I want to combine these two and have a window capture that shows a red rectangle around the element in error.

Alot of forums have answers around this, but they refer to TranslatePoint . I cannot see this when working with Visual Studio and Microsofts UITesting Coded UI WpfControls. Anyone know how to get around this??

Answer 1

Never use coordinates. Instead, get the control and use the DrawHighlight() method. This will draw a blue rectangle outside the control.

Answer 2

TranslatePoint is defined on UIElement . Any UIElement should expose this.

I suspect the problem is that WpfControl is not a WPF UIElement . You should be able to use it's BoundedRectangle property to get the proper surrounding rectangle instead of TranslatePoint on a UIElement .
