I have noticed that grid saves its starte when it comes to :
* Filterexpression
* Sortexpression
* In edit/insert mode
* Wich page to go to
How can we reset viewstate? Why isn't this default behavior when binding new datasource?

Hi Henrik,
Some of this questions are disused in the other thread you started:
http://www.telerik.com/community/forums/aspnet-ajax/grid/how-do-i-cancel-edit-insert-form-by-code.aspx
This is the default behavior because it allows features like custom paging to work.
Here is an example based on this demo:
1) Enable custom paging.
2) Click on second page.
3) On NeedDataSource event perform request to your DataObject and return some records.
4) Set these new records as a DataSource of your grid.
Now if on step 4 you reset the paging index (because of datasource changing) then the paging index will be zero. Which is wrong - it should be one.
It is pretty much the same situation with FilterExpression an the other settings.
Best wishes,

Hello Henrik,
Yes, this is the right approach. If you want to reset the CurrentPageIndex when binding to new datasource, then set yourGrid.CurrentPageindex=0;
All the best,
