I'm working on an interface where I'd like a grid to display as disabled when the form is in a state which shouldn't allow entry into it.

In the first attempt, I created a small transparent PNG that had a darkening effect. I put this on my form and stretched it across the grid and moved it in or out of view when I wanted the grid to appear unavailable. This worked but seemed to be a big graphic hit to VFP. The screen would flicker and the image would take about 2 seconds to draw itself and sometimes is would draw itself twice. Not sure why.

So I thought I'd give GDI+X a try and draw a rectangle with a low alpha channel value set for transparency. I'm fairly new to GDI+X and I'm not seeing a way to do this. If I use the imagecanvas, I can't seem to make that transparent.

Can anyone point me in the right direction?

Thanks.
