ASP.NET 迭代控件获得行号

 

如何获取Repeater的当前行号，其实Repeater自身就带有这个获取当前行号的属性，而无需程序员绑定这个行号。到底要怎么实现呢？其实使用Repeater中的 Container.ItemIndex 就可以获取了，见下示例：

　　Repeater:

        <asp:Repeater ID="Repeater1" runat="server">
            <ItemTemplate>
                行号：
                <%#Container.ItemIndex %>
            </ItemTemplate>
        </asp:Repeater>

　　GirdView:

        <asp:GridView ID="GridView2" runat="server">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <%#  Container.DataItemIndex %>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

　　DataList:

       <asp:DataList ID="DataList1" runat="server">
            <ItemTemplate>
                <%# Container.ItemIndex %>
            </ItemTemplate>
        </asp:DataList>

　　

1. if you are using SQL Server, try

select identity(int,1,1) as 'id', * into #mytemp from YourTable
select * from #mytemp

2. you could add a column to the DataTable:

DataTable1.Columns.Add("ID",typeof(int));
int i=0;
foreach (DataRow dr in DataTable1.Rows)
{
    dr["ID"] = ++i;
}
