Refresh (Reload) DataList control after new record is inserted (updated) in ASP.Net

Sir,

I have a repeater control and a text box, and likewise a button to post data to database.

after i insert the data to the database in thwe click event of the button, the datalist will not update the displayed content. at the end of the button's click even, i added the code line:

Response.Redirect(Request.RawUrl)

But still, the datalist will not update automatically. Please help, what do I do next?
