Hello,

I need help according to set the size of an dialog.

Before I open a PopUp, I set the height and the width of the dialog.

I have the following problem:

1. I open the DIALOG_1 with height = width = 800

2. User close the DIALOG_1.

3. I open the DIALOG_1 with height = width = 400

Then there is the problem that DIALOG_1 has still the old height and width (800), instead of the new height and width(400).

   // will be set before

   //unusedWinNr

   //aryDialogs[unusedWinNr].height 

   //aryDialogs[unusedWinNr].width

   double dblTop  = (App.Current.Host.Content.ActualHeight -aryDialogs[unusedWinNr].height / 2);

double dblLeft = (App.Current.Host.Content.ActualWidth   -aryDialogs[unusedWinNr].width  / 2);

Dialog myDialog = (Dialog)LayoutRoot.FindName("DIALOG_" +unusedWinNr);

    myDialog.Name = "DIALOG_" +unusedWinNr;

myDialog.IsMaximizeEnabled = aryDialogs[unusedWinNr].hasMaxButton;

myDialog.IsResizable           = aryDialogs[unusedWinNr].isResizable;

//size

    myDialog.Height                = aryDialogs[unusedWinNr].height;

myDialog.Width                   = aryDialogs[unusedWinNr].width;

//position

    myDialog.HorizontalOffset     = dblLeft;

myDialog.VerticalOffset         = dblTop;

myDialog.Show();

myDialog.BringToFront();

thanks for any help!

regards

Hi Jens,

After altering the size of the Dialog you need to call the method Dialog.UpdateSize() to ensure the Dialog resizes correctly.

Thanks!
