DataTable dt = (DataTable)Session["additems"];
       if (dt.Rows.Count > 0)
       {
           dt.Rows.RemoveAt(e.RowIndex);
       }
       Session["additems"] = dt;
       bindGrid();

推荐答案

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
 {
     dt = (DataTable)ViewState["dt"];
     dt.Rows[e.RowIndex].Delete();
     GridView1.DataSource = dt;
     GridView1.DataBind();
 }
