R – WPF window resizing – no preview / show rubber band

direct3ddirectxresizewpf

Is there a way to force a WPF window to use a rubber band (no live preview of contents during resize) when resizing?

I realize this is usually a user preference on Windows but my application uses D3D windows and there is significant flicker when resizing (particularly from the top left corner outward).

I should have mentioned I am using DX10 via SlimDX. I haven't found a way to use D3DImage with DX10. Is this possible?

The best option, in this case, is to use the D3DImage class to present your DX content within WPF. This allows you to have smooth scaling Direct3D content within WPF - with no flickering. In addition, this provides much more complex compositing options, since airspace is no longer an issue.

C# – Bring a window to the front in WPF

myWindow.Activate();

Attempts to bring the window to the foreground and activates it.

That should do the trick, unless I misunderstood and you want Always on Top behavior. In that case you want:

myWindow.TopMost = true;

C# – Find all controls in WPF Window by type

This should do the trick

public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
{
    if (depObj == null)
        return;
    
    for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
    {
        var child = VisualTreeHelper.GetChild(depObj, i);

        if (child != null && child is T)
            yield return (T)child;
                
        foreach (T childOfChild in FindVisualChildren<T>(child))
            yield return childOfChild;
    }
}

then you enumerate over the controls like so

foreach (var tb in FindVisualChildren<TextBlock>(window))
{
    // do something with tb here
}
