I am having the same problem and it was driving me nuts! Anyways, I came up with a temporary work-around. First off, I always display a custom control inside of a dialog so you may have to modify a bit if you have code inline.

Set the WindowStartupLocation to Manual and then hook into the custom control's Loaded event and add the following code:

    
            private void Dialog_Loaded(object sender, RoutedEventArgs e) 
        
            { 

               var window = RadWindow.GetParentRadWindow(this); 
        
               window.Left = Application.Current.Host.Content.ActualWidth / 2 - this.ActualWidth / 2; 
        
               window.Top = Application.Current.Host.Content.ActualHeight / 2 - this.ActualHeight / 2; 
        
            }

A real fix will be nice but this works ok for now.

Hello to all,

We are appologizing for the caused inconvenience, it turns out that we have introduced a bug with the latest changes in our RadWindow. Currently, you can set the ModalBackground of any dialog windows using the ModalBackground property of DialogParameters like this:

    
             RadWindow.Alert(new DialogParameters() { ModalBackground = new SolidColorBrush(Colors.Black) });

We will response with a hotfix in a couple of days, which will not require you to set any locations or brushesh. Please excuses for this bug again, and we hope that issue will not be a show stopper for you until we provide you with a hot fix.

I like your solution better. The following below "almost" worked but since I did not specify a size on the window directly, the width was too "narrow". Explicitly setting a size on the window and then using CenterParent did the trick.

RadWindow window = new RadWindow()

{

};

Page p = new Page();

window.Content = p;

window.WindowStartupLocation =

WindowStartupLocation.CenterParent;

window.Header =

"RadWindow";

window.Top = 0;

window.Left =0;

window.LeftOffset = 0;

window.TopOffset =0;

p.SizeChanged +=

new SizeChangedEventHandler(mySizeChange);

window.ShowDialog();
.....

private

void mySizeChange(object o, SizeChangedEventArgs e)

{

int i = 0;

if (e.PreviousSize == new Size(0, 0))

{

Page p = o as Page;

RadWindow w = p.Parent as RadWindow;

w.Height = e.NewSize.Height;

w.Width = e.NewSize.Width;

}
