Position of Horizontal ScrollBar on Postback

I don't think Suthish's solution will work, and it would also cause a lot of unnecessary post backs.  (I'm sorry.)  There's no simple fix.

If you absolutely must maintain the horizontal scroll position, I think you're going to have to write some Javascript.  You need Javascript to record the scroll position and then you need more Javascript to put the browser back to the same spot after the post back.  The article I listed had one technique.  There are others out there, if you spend some time searching on the Web.

Thanks for reply,

      I tried given solution but its not working. Actually we tried to convince client with select row and modify details. but they want excel like user experience.

 Am not sure, this will help. But give a try...

 Set Focus Controls - AutoPostBack = true

I beleive the MaintainScrollPosition setting is only for the vertical position.  Also, it doesn't work on every browser. 

You can write code to do what you want, although it's a bit of a pain.  See, for example, http://www.4guysfromrolla.com/articles/111704-1.aspx

It's problems like this that have led me to prohibit editing inside the grid in all apps.  It's already a bad experience.  Some columns are editable and others aren't, which can be confusing.  When your user has to use a horizontal scroll to edit all the columns, it's worse.  Also, you end up having problems like the one you're having.

I always have the user select a row, and then I display a panel where all the values can be displayed / edited.  I do the same thing even when the grid only has a few columns.  That way you have the same user experience in every grid throughout the application.
