Use this:

C#

if(sdr.HasRows)
{
        GRIDVIEWITEM_BILL.DataSource = dr;
        GRIDVIEWITEM_BILL.DataBind();
}

OR

C#

SqlDataAdapter da = new SqlDataAdapter();
DataTable dt = new DataTable();
da = new SqlDataAdapter(sql,ConnectionString);
da.Fill(dt);
GRIDVIEWITEM_BILL.DataSource = dr;
GRIDVIEWITEM_BILL.DataBind();
