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">


<ItemStyle HorizontalAlign="Center" />


<HeaderStyle HorizontalAlign="Center" Width="5%" />


<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" Width="5%" />


<ItemTemplate>


<asp:Label ID="Label2" runat="server" Text='<%# this.MyListGridView.PageIndex * this.MyListGridView.PageSize + this.MyListGridView.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" >


<ItemStyle HorizontalAlign="Center" />


<HeaderStyle HorizontalAlign="Center" Width="5%" />


</asp:BoundField>


protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)






{


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






{


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


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


}


}
