ASP.NET postback in popup window

Here's a tip if you need to do an ASP.NET postback in a popup window. I was using the JavaScript showModalDialog function to launch an ASP.NET page in a popup window. Which worked great, until I clicked on a button that posted back. As soon as I clicked on button that posted back, it opened a new window. Not exactly what I expected.

So after a little searching on the web, I found a simple solution. You need to include this:

<base target="_self">

in the <head> section of the page. As soon as I did that, it posted back to the popup window.
