Please help me.if (grdItemDescriptionLoad.Rows.Count > 0) { for (int i = 0; i < grdItemDescriptionLoad.Rows.Count; i++) { CheckBox chkb = (CheckBox)grdItemDescriptionLoad.Rows[i].FindControl("chkSelect"); if (chkb.Checked == true) { SqlCommand cmd3 = new SqlCommand("Smt_Mc_Repair_Details_Record_Save", cn); if (cn.State == ConnectionState.Closed) { cn.Open(); } cmd3.CommandType = CommandType.StoredProcedure; cmd3.Parameters.AddWithValue("@SMcID", hdAction.Value); cmd3.Parameters.AddWithValue("@SAssetNo", ddlAssetNo.SelectedValue); cmd3.Parameters.AddWithValue("@SSevID", grdItemDescriptionLoad.Rows[i].Cells[1].Text.Trim()); cmd3.Parameters.AddWithValue("@SevNo", grdItemDescriptionLoad.Rows[i].Cells[2].Text.Trim()); cmd3.Parameters.AddWithValue("@SMcRepairDtl", grdItemDescriptionLoad.Rows[i].Cells[3].Text.Trim()); cmd3.ExecuteNonQuery(); } } }Here is my gridview<asp:GridView ID="grdItemDescriptionLoad" runat="server" <rowstyle cssclass="grdRow" /> <HeaderStyle CssClass="gridheader" /> <columns> <asp:TemplateField HeaderText="Check"> <itemtemplate> <asp:CheckBox ID="chkSelect" Width="25px" runat="server" AutoPostBack="True" oncheckedchanged="chkSelect_CheckedChanged" /> </itemtemplate> <asp:BoundField DataField="SevID" HeaderText="SevID" SortExpression="SevID" /> <asp:BoundField DataField="SevNo" HeaderText="Service No" SortExpression="SevNo" /> <asp:BoundField DataField="SevType" HeaderText="Service Description" SortExpression="SevType" /> </columns> 解决方案 Use css class to hide the field instead of setting visible=false.For example:<style type="text/css"> .hidden { display:none; }</style><asp:boundfield datafield="SevID" headertext="SevID" sortexpression="SevID"><itemstyle cssclass="hidden" /></asp:boundfield> 这篇关于返回gridview边界值。的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
