how will i refresh the page

hi dear,

when you execute Insert, Delete or Update process then Reload your Refresh function.

By default in asp.net click on every button post back the page.
By doing Response.redirect("tosomepage.aspx") you will loose view state if any important data. how you are doing insert/update/delete?

call the pageload function as

Page_Load(this,e);
whenever u want....

after completing your add, update and delete functionality just call your function binding function.

or you can use redicturl of the same page.

Response.Redirect("SamePageURL");
