[Solved] ASP.Net Datapager PreRender event is firing on each Postback

I don't now what's happening but it seems to be working now, like you said the Datapager1_Prerender code after

initial page load will run, but now working fine only firing on my desired button click

with this code in the button click DataPager1_PreRender(null, null);

Sorry for that but thank you very much for your help
