How Can I Only Allow Uniform Resizing in a WPF Win

Question

I don't want my window to be resized either "only horizontally" or "only vertically." Is there a property I can set on my window that can enforce this, or is there a nifty code-behind trick I can use?

Answer 1

You could try replicating an effect that I often see on Flash Video websites. They allow you to expand the browser window any way you like, but only stretch the presentation area so that it fits the smallest of the height or width.

For example, if you stretch the window vertically, your application would not resize. It would simple add black bars to the top and bottom of the display area and remain vertically centered.

This may or may not be possible with WPF; I don't know.

This may be bit late but you can simply put it in your code behind....

Private Sub UserControl1_SizeChanged(ByVal sender As Object, ByVal e As System.Windows.SizeChangedEventArgs) Handles Me.SizeChanged
    If e.HeightChanged Then
        Me.Width = Me.Height
    Else
        Me.Height = Me.Width
    End If
End Sub
