I have 2 grid views in a page like gridview2 and gridview3, when user click on gridview3 I fetch the data and filled in gridview2 depend on unique number from gridview3 after that user can delete the data and add data in gridview2 (not from database) , I written code it's deleting data from gridview2 but row was not removing (empty row showing)

thanks

What I have tried:

stored the data in dtp datatable
in GridView3_SelectedIndexChanged
{
Session["rdt"] = dtp;
GridView2.DataSource = Session["rdt"];
GridView2.DataBind();
}
---------------------------
in GridView2_RowDeleting
int index = Convert.ToInt32(e.RowIndex);
DataTable dt = (DataTable)Session["rdt"] as DataTable;
dt.Rows[index].Delete();
Session["rdt"] = dt;
GridView2.DataSource = dt;
GridView2.DataBind();
