I have a Telerik RAD Grid which i am bindng on client side. i have another button(Button 2) which when clicked will do a postback and get the values of the grid and call the database to perform some activity, but in the Button 2 Click event, values of the grid are lost and also the grid after Button 2 click has empty data. See below sample code.
