Hi

I'm trying to make the entire grid clickable - even the empty cells should fire a click event.
When I set the background attribute of the layoutroot (grid) to transparent (Background="Transparent"), the grid responds to the click event, but everything turns black!

In WPF this issue can be solved by setting AllowsTransparency="True", but this attribut seems not to exist in NoesisGUI.

How can this be solved in NoesisGUI?

Thank you for your help.

This is a problem we had in 1.1 version. It happens that we use the first element that draws to the surface to decide whether to do a Clear of the color buffer. If that first item fills the entire surface and has a background with a SolidColorBrush, then we do a Clear operation instead of drawing a quad.

That is what is happening in your sample, because the layoutRoot Grid is probably the first element being rendered and has the exact surface dimensions, then we are doing a Clear with a Transparent color, which means that everything gets black. If you want to avoid this, you can make your Grid a bit smaller or bigger using the Margin: Because this is less than intuitive, we changed it in 1.2. In that version you don't have to worry about anything, we only do a Clear when rendering to texture, so you can start with a transparent texture.

Thanks, this worked for me!
