Question

I had booked a Grid with HorizontalAlignment = "Stretch"

Let's say that you have the following grid:

<Grid Name="gvDummyContent" HorizontalAlignment="Stretch" />

An you want to get the height and width of it. You can do it like this:

double actualWidth = gvDummyContent.ActualWidth;
double actualHeight = gvDummyContent.ActualHeight;

Be sure that you are calling these properties after the controls are loaded.
