Hi

i have one grid in my page , this gird should be binding data base on search , means i have about 4-5 search fields and base on that i have to bind that grid in my page , after that i  need selected row and selected row change event for that gird ,

my problem is i can't find selected index chage event for that gird , because i bind that gird in search button click event , i know i have to bind grid in datasource event , but i can't understand how to bind gird base on search fields and get row change  event

i also use BO/enity collection class for bind grid not dataset or data reader

and i also lost my gird data data when page is postback two time , i used ajax updatepane too

i want to know how to do paging in grid , i have to bind or call same mathod every time when user select another page number

and every post back that grid data bind method would be fire ?
