UserControl Location in WPF

Question

I am new in WPF, I created a new UserControl MyUserControl.

Now I am surprised: the UserContol does not have a location.

How can I read (by code) myUserCont

The WPF layout system doesn't use absolute positioning, unless you're placing your controls on a container that supports absolute positioning (typically a Canvas). If you're using a Canvas, you can get or set the position of the control using the Canvas.Left, Canvas.Right, Canvas.Top and Canvas.Bottom attached properties:

double x = Canvas.GetLeft(myControl);
double y = Canvas.GetTop(myControl);

Now, if you want the actual location of the control (relative to its parent), you can use the VisualTreeHelper.GetOffset method:

Vector offset = VisualTreeHelper.GetOffset(myControl);
double x = offset.X;
double y = offset.Y;
