Capture Web Screenshots easily with the [GrabzIt C# API](http://grabz.it/api/aspnet/).

This handy code snippet will fire a event when your screenshot is ready so that your code can process the screenshot anyway you wish!

You will need the free [GrabzIt Code Library](http://grabz.it/api/aspnet/download.aspx) to get started.

The code snippet assumes it is located within a ASPX page, in this example we are taking a screenshot of google.com.
