this doesnt happen automatically...you need to manually disable the other stuff.

Are you able to point me in the right direction on how to do that? I'm looking at the sampleWebsite and the video and I have no idea, besides in the style, on where they gray out the background page

just as you said... in styles.

What I've done is wrap it all in a container that I set to Enabled=False when they click the button/link/etc that causes the Popup

I have anexample of making a modal UpdateProgress. You should be able to use similar styles for the BackgroundCssClass as I do in the#progressBackgroundFilterexample

For example:

.modalBackground{
background-color:#000;
filter:alpha(opacity=50);
opacity:0.5;
}
