Question

我正在使用嵌套的GridView。单击编辑时，项目将显示在texbox中进行编辑，但新值不会反映在rowupdating中。我尝试通过浏览器进行检查，即便如此，它也会获取旧值。

 <asp:GridView ID="GVInvoiceDet" runat="server" Width="100%" AutoGenerateColumns="False" EnableViewState="False"
            HorizontalAlign="Left" BorderStyle="Outset" OnRowCancelingEdit="GVInvoiceDet_RowCancelingEdit"
            OnRowEditing="GVInvoiceDet_RowEditing" OnRowDataBound="GVInvoiceDet_RowDataBound" ShowFooter="True"
            OnRowCommand="GVInvoiceDet_RowCommand" OnRowUpdating="GVInvoiceDet_RowUpdating"
            OnRowDeleting="GVInvoiceDet_RowDeleting" OnRowDeleted="GVInvoiceDet_RowDeleted"
            OnRowUpdated="GVInvoiceDet_RowUpdated" AllowSorting="True" DataSourceID="DSItemGrid" DataKeyNames="invoiceno,itemcd">

    </div>

前端网格的快照，显示新的数量值500

显示旧数量值50的浏览器检查元素的快照。

行更新的部分代码也是数量

的旧值

 protected void GVInvoiceDet_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {
            GridView temp = (GridView)sender;
            //Get the values stored in the text boxes
            string itemCode = ((TextBox)temp.Rows[e.RowIndex].FindControl("txtItemCode")).Text;
            string quantity = ((TextBox)temp.Rows[e.RowIndex].FindControl("txtItemQty")).Text;
            string unitRate = ((TextBox)temp.Rows[e.RowIndex].FindControl("txtItemUnitRate")).Text;
            string unitValue = ((TextBox)temp.Rows[e.RowIndex].FindControl("txtItemUnitValue")).Text;    
            string unit = Session["unit"].ToString();
            string proj = Session["project"].ToString();

在这里，您可以尝试使用此代码更新行

 protected void GVInvoiceDet_RowUpdating(object sender, GridViewRowEventArgs e)
 {
    string itemCode= (TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemCode")).Text;
    string quantity = (TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemQty")).Text;
    string unitRate = ((TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemUnitRate")).Text;
    string unitValue = ((TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemUnitValue")).Text;    
    string unit = Session["unit"].ToString();
    string proj = Session["project"].ToString();
    GVInvoiceDet.EditIndex = -1;
    // call bind grid method here
 }

Asp GridView没有更新
