 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
{
 DataRowView drv = (DataRowView)e.Row.DataItem;
            if (drv.Row["Fetch_status"].ToString() == "已领")
            {

                lbtn.Enabled = false;              
                lbtn.ForeColor = System.Drawing.Color.Gray;
　　　　　　　　
　　　　　　　　　//某一列不显示
　　　　　　　　　GridView1.Columns[2].Visible = false;

            } 
　　　　　　　else if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
