            string qry = "";
            qry = string.Format("select * from TABLE NAME where 1=1");
           
            if (txt_name.Text != "")
            {
                qry = qry + "and name='" + txt_name.Text + "'";
            }
          
// bind the grid view, if want to show search result in grid view or where ever you want
            sql_detail.SelectCommand = qry;
            gv_detail.DataBind();
            if (gv_detail.Rows.Count > 0)
            {
                lbl_msg.Text = "";
                lbl_msg.Visible = false;
            }
