WPF window resizing - no preview / show rubber band

4

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.

Agreed with Reed, D3DImage class has what you need. I don't think there is a way otherwise to prevent redraw when resizing save for overloading a heck of a lot of window events in an ugly way.
