Repeater嵌套

Repeater嵌套经常要用到，总结一下。

 

                <asp:Repeater ID="repSingle" runat="server" onitemcommand="repSingle_ItemCommand" onitemdatabound="repSingle_ItemDataBound">
                    <ItemTemplate>
                        <li>序号<asp:TextBox ID="texTrueFalseSequence" runat="server" Width="20px" Text='<%#Eval("Sequence")%>'></asp:TextBox>&nbsp;&nbsp;<%#Eval("QuestionTitle")%></li>
                        <!--begin选项-->
                        <li>
                            <ul>
                                <asp:Repeater ID="repSingleChoices" runat="server">
                                    <ItemTemplate>
                                        <li><%# Container.ItemIndex + 1%>，<%#Eval("ItemContent")%></li>
                                    </ItemTemplate>
                                </asp:Repeater>
                            </ul>
                        </li>
                        <!--end选项-->
                    </ItemTemplate>
                </asp:Repeater>

 

 

    protected void repSingle_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater singleChoice = e.Item.FindControl("repSingleChoices") as Repeater;
            Question row = (Question)e.Item.DataItem;
            //int curSequence = Convert.ToInt32(row["Sequence"].ToString());
            //Question curQuestion = questionnaire.Questions.Find(a => (a.QuestionType == QuestionType.singlechoice && a.Sequence == curSequence));
            singleChoice.DataSource = row.ChoiceItems;
            singleChoice.DataBind();
        }
    }

发现一个现象，即使没有设置AlternatingItem，默认仍然会在第一行是ListItemType.Item，第二行是ListItemType.AlternatingItem，如此交替下去
