GridView 自动增加序号

第一种方式,直接在Aspx页面GridView模板列中.这种的缺点是到第二页分页时又重新开始了.

<asp:TemplateField HeaderText="序号" InsertVisible="False">

<ItemTemplate>

<%#Container.DataItemIndex+1%>

</ItemTemplate>

</asp:TemplateField>

第二种方式分页时进行了计算,这样会累计向下加.


<asp:TemplateField
HeaderText="序号" InsertVisible="False">

<ItemStyle HorizontalAlign="Center" />

<HeaderStyle HorizontalAlign="Center"/>

<ItemTemplate>

<asp:Label ID="Label2" runat="server" Text='<%# this.GridView1.PageIndex * this.GridView1.PageSize + this.GridView1.Rows.Count + 1%>' />

</ItemTemplate>

</asp:TemplateField>

还有一种方式放在cs代码中,和第二种相似.

<asp:BoundField HeaderText="序号" ></asp:BoundField>

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

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

{

int indexID = this.GridView1.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1;

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

}

}
