Sum of an Gridview Column should be shown in the last row of Gridview

You can calculateit in the RowDataBound event and display on the Footer.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
 {
  Label lblqy = (Label)e.Row.FindControl("lblqty");
  int qty = Int32.Parse(lblqy.Text );
  total = total + qty;
 }
 if (e.Row.RowType == DataControlRowType.Footer)
 {
  Label lblTotalqty = (Label)e.Row.FindControl("lblTotalqty");
  lblTotalqty.Text = total.ToString();
 }
}

        string strConnString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        string str;
        SqlCommand com;
        SqlDataAdapter sqlda;
        DataSet ds;

       

        void bind()
        {
        SqlConnection con = new SqlConnection(strConnString);
        con.Open();
        str = "select * from test";
        com =new SqlCommand(str, con);
        sqlda = new SqlDataAdapter(str, con);
        ds =new DataSet();
        sqlda.Fill(ds, "test");
        GridView1.DataSource = ds;
        GridView1.DataMember = "test";
        GridView1.DataBind();

        }
        public string totalbills()
        {

            decimal Totalbill = Convert.ToDecimal(com.ExecuteScalar());
            con.Close();
            con.Dispose();
            com.Dispose();

hi Aamir,

You can achieve this by using ItemTemplate (FooterTemplate) and RowBound event.

Please Refer below link for example.
