1. In the example http://www.telerik.com/demos/aspnet/prometheus/Grid/Examples/Programming/PagerTemplate/DefaultCS.aspx add a checkbox with checked=true
2. Uncheck it.
3. Change the page - the checkbox will be checked again, i.e. restores the original value.

All the pager controls in the example would restore the original values if you don't init them with the current grid values.

Hi miksh,

You cannot automatically persist the state of the control when you page the Grid, because it is rebound. You can see that it is working as you want it to when executing postbacks which do not rebind the Grid. The following help article which explains how to persist the CheckBox control state in GridTemplateColumn on rebind might be helpful for you. I think a similar approach can be used for a checkbox in the PagerTemplate as well.
