Hi Manpreet,
we are using the client side click event of a button. on that function we are calling spread.update(). after spread.update() it goes to the server side. on server side function we are using ScriptManager.registerclientscript. that is not working.
In Farpoint 3.0 version it was working. but after upgrade v3.0 to v7 it is not working
