GridView实现自动编号

效果图：



实现方法：

双击GridView的OnRowDataBound事件；

在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)

{

if (e.Row.RowIndex != -1)

{

int id = e.Row.RowIndex + 1;

e.Row.Cells[0].Text = id.ToString();

}

}

注意这时最好把前台的第一列的表头该为“编号”，因为以前的第一列被“吃掉”了。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDataBound="GridView1_RowDataBound">

<FooterStyle BackColor="White" ForeColor="#000066" />

<Columns>

<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

<asp:BoundField DataField="姓名" HeaderText="用户姓名" />

<asp:BoundField DataField="员工性别" HeaderText="性别" />

<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />

<asp:CommandField HeaderText="选择" ShowSelectButton="True" />

<asp:CommandField HeaderText="编辑" ShowEditButton="True" />

<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />

</Columns>

<RowStyle ForeColor="#000066" />

<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

</asp:GridView>
