Checkbox in Gridview - selection does not persist

Question

Hi all...

 

I have to use Telerik Controls for one portal... I am stuck up in RadGrid control..

 

Requirement -

I have to bind the RadGrid to dataset, that has more than 200 rows. - Done.

I have done paging (10 records per page). - Done.

Now, I have to add a check box in the RadGrid to select particular rows - Done

 

Issue -

Now, on first page, there are 10 records.

Here I select 4 records (check the checkbox), and move to 2nd page, and select 2 records on 2nd Page.

Now, when I again move to Page-1 (previous page), then the selection is gone.

 

How to persist this ?

Please guide...
