Repeater动态生成列这样为什么不行？

Question

            <asp:Repeater ID="Repeater1" runat="server">
                <ItemTemplate>
                    <tr>
                        <%
                            for (int i = 0; i < 3; i++)
                            {
                        %>
                        <td>
                            <%#Eval("column" + i)%>
                        </td>
                        <%
                            }
                        %>
                    </tr>
                </ItemTemplate>
            </asp:Repeater>
<%#Eval("column" + i)%> 这行提示"当前上下文中不存在名称i"。为什么不识别i呢？

Answer 1

这个写得有点精灵古怪，其实你可以写到Repeater的ItemDataBound事件中去，动态生成列。

Answer 2

        <asp:Repeater ID="Repeater1" runat="server">
            <ItemTemplate>
                <%for (int i = 0; i < 3; i++){%>
                <td>
                    <% Response.Write(Eval("colums" + i.ToString()));%>
                </td>
                <%}%>
            </ItemTemplate>
        </asp:Repeater>
这样试试

Answer 3

这样不行，报错
"Eval()、XPath() 和 Bind() 这类数据绑定方法只能在数据绑定控件的上下文中使用。 "

Answer 4

<%#Eval("column" + i)%>改成这个试一下,<%i+#Eval("column")%>

Answer 5

<asp:Repeater ID="Repeater1" runat="server">

                <%for (int i = 0; i < 3; i++){%>
                <td>
                    <% Response.Write(Eval("colums" + i.ToString()));%>
                </td>
                <%}%>
            </ItemTemplate>
        </asp:Repeater>

在后台写，在ItemDataBound事件里面
