Screen Scrolling on Postback

Last night I was watching a DotNetRocks TV broadcast by Peter Blum on Web Controls and Validation. During his presentation, Peter said something, in passing, that triggered a major “ah ha” moment. One where you dent your forehead with your palm.

He mentioned a property that was added to the Page object in .NET 2.0 called MaintainScrollPositionOnPostback. I stopped the video right then, pulled up my Visual Studio, and tried it out. It worked!

One of the problems we’ve had in our CMS system is that when you change certain publishing options, it triggers a PostBack of the page. Basically, the page gets posted to the server, then reloaded on the browser. When this happens, it takes you to the top of the page in the browser. The publishing options are at the bottom of the page, so the user needs to scroll back down to where they were. Not cool.

With this new feature in .NET 2.0, we can add one line of code with will make the PostBack return you to the previous location on the screen. The code is:

Page.MaintainScrollPositionOnPostBack = true;

Now I just need to figure out where is the best place to use this feature. Right now I’m thinking it should go in the UserControl that displays the publish options on the edit screen.
