Obtain a size of UIElement after the initialisation

Question

I am trying to develop a program that has the possibility to adapt at the screen resolution of the user.

I am using mvvm with the pushbinding of Meleak to obtain the actual size of my MainWindow:

For positioning my object, I am using GridRow and GridColumn. Now I am trying to optimize this size, for that I have the need to get the ActualSize of my other UIElment, but like their size depend of their contents, I don't know how I can get their size, I try with a binding onewaytosource but I obtain a size of 0.0 and obviously is not the size after initialisation.

I have edited your question to what I think you were trying to say, I think you will need to add more details though. — Gaz Winter, Jun 19 '12 at 10:26
@Gat: You have any sample code for what you're trying to do? — Fredrik Hedblad, Jun 19 '12 at 10:33
@Meleak : you can find an example here : https://docs.google.com/file/d/0B5Iv6R2fQq3UV1JJZ09iNlBNTm8/edit?pli=1 — Gat, Jun 19 '12 at 13:39
@Meleak just remove .doc, else in this example is a border(in my project it is datagrid) that has this size depend of listbox, but if you resize the mywindow,you can see it has inifiny size. — Gat, Jun 19 '12 at 13:41

The event Loaded can be used to measure the ActualHeight of a visual object.

If this is used on the window as below, the internal content should all be rendered and be available for you to reference.

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    var temp = this.ActualHeight;
}

In this example I am finding the window's ActualHeight but you can use it for any object within the window.

If you have nested windows/views the Loaded event is available on them as well.
