UIElement position relative to Window

Question

In WPF, I want to get the corner location of a `TabControl` in my code, so I can set a ToolWindow's location accordingly when shown. How do I get the location of a given `UIElement`? ``` buildingInfoWindow = new BuildingInfoWindow(); // BuildingWindow : System.Windows.Window buildingInfoWindow.Owner = this; //buildingInfoWindow.Left = ?; // relative X coordinate of my TabControl //buildingInfoWindow.Top = ?; // relative Y coordinate of my TabControl ```

Accepted Answer

```
Point pt = tabControl.TranslatePoint(new Point(0, 0), windowInstance);
```
