How to redirect after gridview row updating?

Hello Experts,

I use the following on a button to redirect the user to the same page when it's clicked:

protected void btn_refresh_emp_name_ddl_Click(object sender, EventArgs e)
        {
            Response.Redirect(Request.RawUrl);
        }

Select allOpen in new window

I would like to do the same thing when a gridview row is updated, so I tried this:

protected void tbl_emp_gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {
            Response.Redirect(Request.RawUrl);
        } 

Select allOpen in new window

but it didn't work.  

Any help would be greatly appreciated.

Thanks,
J
