如何获取隐藏列值 [英] How to get Hidden Column value

问题描述

这是我的网格视图

This is my grid view

<asp:GridView ID="grdDepartment" runat="server" BackColor="White"

               BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3"

               ForeColor="Black" GridLines="Vertical" Width="293px"

               AutoGenerateColumns="False" AutoGenerateSelectButton="True"

               onselectedindexchanged="grdDepartment_SelectedIndexChanged">
               <AlternatingRowStyle BackColor="#CCCCCC" />
               <FooterStyle BackColor="#CCCCCC" />
               <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
               <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
               <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
               <SortedAscendingCellStyle BackColor="#F1F1F1" />
               <SortedAscendingHeaderStyle BackColor="#808080" />
               <SortedDescendingCellStyle BackColor="#CAC9C9" />
               <SortedDescendingHeaderStyle BackColor="#383838" />
               <Columns>
                   <asp:BoundField HeaderText ="ID" DataField ="ID" Visible="false" />
                   <asp:BoundField  HeaderText="Department" DataField="Department Name"/>
               </Columns>
           </asp:GridView>

我无法访问ID col的值以下代码：/ b $ b

and i am unable to access value of ID column by below code

protected void grdDepartment_SelectedIndexChanged(object sender, EventArgs e)
    {
        lblID.Text = grdDepartment.SelectedRow.Cells[1].Text;
        txtDepartment.Text = grdDepartment.SelectedRow.Cells[2].Text;
    }

推荐答案

试试这个，

try this,

<asp:BoundField HeaderText ="ID" DataField ="ID"  />

删除visible =false并从后面的代码设置visible = false。

remove visible="false" and set visible=false from code behind.

lblID.Text = grdDepartment.SelectedRow.Cells[0].Text;
txtDepartment.Text = grdDepartment.SelectedRow.Cells[1].Text;
 grdDepartment.Columns.Item(0).Visible =false;

谢谢

您需要使用 DataItem 。关注：

You need to use DataItem . Follow:

DataRowView rowView = (DataRowView)e.Row.DataItem;
int id = Convert.ToInt32(rowView["ID"]);
//use id as your need..
