我正在尝试使用gridview编辑更新数据库,Update CommandField。我有两个可编辑字段,它在编辑模式下显示为文本框。单击提交时,我正在尝试将文本框值放入变量以进行工作,但我无法访问它们。两个列名称为“EOR”和“CategoryName”。我在其他论坛上找到了几个建议,以尝试:

protected void ResultGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 
    TextBox txtEor = (TextBox)myGridName.Rows[e.RowIndex].FindControl("EOR"); 
.

当我调试程序时,Txteor始终为空。我唯一能想到的是我没有正确引用该电池。我设置了Headertext,AccessibleHeadertext,DataField和SortExpression到“EOR”,但它仍然只是unull。

任何帮助将非常感谢!

                <asp:BoundField DataField="EOR" HeaderText="EOR" SortExpression="EOR" 
                    AccessibleHeaderText="EOR"/>
                <asp:BoundField DataField="CategoryName" HeaderText="CategoryName" 
                    SortExpression="CategoryName" />
                <asp:CommandField ButtonType="Button" ShowDeleteButton="True" 
                    ShowEditButton="True" />


            </Columns>
            <FooterStyle BackColor="#CCCCCC" />
            <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
            <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
            <AlternatingRowStyle BackColor="#CCCCCC" BorderColor="Black" 
                BorderStyle="Solid" BorderWidth="5px" />
        </asp:GridView>
.

有帮助吗?

解决方案

我终于找到了一种方法:

        string newEor = ((TextBox)grdEOR.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
        string newCategoryName = ((TextBox)grdEOR.Rows[e.RowIndex].Cells[2].Controls[0]).Text;
.
