Your page is posting back because of the autopostback="true" on the checkbox, thus hiding the modal popup.

Look up 'ASP.Net Page Lifecycle' for further understandinf. It is important to know how this works.

I'm sure you'd also like to know how to solve this.

You could:

1. Set AutoWireUp=false on the page, but then you'd have to wire all events on the page manually. Since you aren't familiar with the Page Lifecycle, I'm not sure how successful you'd be.

2. Use a javascript-only modal popup.

3. Perhaps an UpdatePanel can be used.
