Repeater嵌套的问题谁能帮我啊谢谢啦

Question

我的项目使用三层做的，网上的代码我都看不懂啊请大家帮帮我啊！
this.Repeater1.DataSource=PlateManager.GetPlateAllBytid(1); //Repeater1的数据源是一个Ilist<plate>的集合，网上的好像用的都是dataset
this.Repeater2.DataSource=PlateManager.GetPlateByPid(p.id); //Repeater2的数据源是一个Ilist<plate>的集合,里边的参数是plate实体类里边的id属性；就是这样啦怎么样才能把Repeater2嵌套在Repeater1里边啊数据源就用这两个，我在线等回答谢谢大家了！

Answer 1

        protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater Repeater2= (Repeater)e.Item.FindControl("Repeater2");
                if (Repeater2!= null)
                {
                    string id = ((DataRowView)e.Item.DataItem).Row["Order_ID"].ToString();// Order_ID改成你plate 的id
                    Repeater2.DataSource = PlateManager.GetPlateByPid(p.id);             Repeater2.DataBind();
                }            }
        }

Answer 2

protected void rptTop_ItemDataBound(object sender, RepeaterItemEventArgs e)
  {
  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  {
  Repeater rpt = (Repeater)e.Item.FindControl("rptchild");
  T t= (T)e.Item.DataItem;  }
    
  }
或
<asp:Repeater ID="rptchild" runat="server"  DataSource='<%#Getdata(Eval("id")) %>' >
public List<T> rptchild(object o)
{...

Answer 3

Repeater嵌套绑定Repeater 

Answer 4

DataRowView用这个不行啊因为我Repeater1里边的数据源是IList<plate>的泛型集合，所以e.Item.DataItem的类型是object类型的不能强制转换成DataRowView，谁能告诉我Repeater1改用什么数据源啊

Answer 5

4楼的我用T t= (T)e.Item.DataItem;
可是那个t里边根本获取不到里边的属性。没有t.id这个属性啊

<table>
                <asp:Repeater runat="server" ID="rptypelist" OnItemDataBound="rptypelist_ItemDataBound">
                    <ItemTemplate>
                        <tr style="background-color: ThreeDShadow;">
                            <td>
                                <input id="txtID" type="text" value='<%#Eval("Id")%>' runat="server" visible="false" />

                        </tr>
                        <tr>
                            <td colspan="3">
                                <table id="askTop" style="margin-left: 10px;" width="100%">
                                    <asp:Repeater runat="server" ID="rpquestionlist">
                                        <ItemTemplate>
                                            <tr>

                                                </td>
                                            </tr>
                                        </ItemTemplate>
                                    </asp:Repeater>
                                </table>
                            </td>
                        </tr>
                    </ItemTemplate>
                </asp:Repeater>
            </table>  private void RpTypeBind(int uid)
    {
        this.rptypelist.DataSource = ArticlesManager.GetUserAllArticles(uid);
        this.rptypelist.DataBind();
    }    protected void rptypelist_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater rep = e.Item.FindControl("rpquestionlist") as Repeater;
            //HtmlInputText txtID = (HtmlInputText)e.Item.FindControl("txtID");
            //int articleId = Convert.ToInt32(txtID.Value);
            Articles rowv = (Articles)e.Item.DataItem;
            int articleId = rowv.Id;
            rep.DataSource = CommentsManager.CommentsByArticel(articleId);
            rep.DataBind();
        }
    }
我用了二种方法，可以用隐藏域<input id="txtID" type="text" value='<%#Eval("Id")%>' runat="server" visible="false" />
再用HtmlInputText txtID = (HtmlInputText)e.Item.FindControl("txtID");
 int articleId = Convert.ToInt32(txtID.Value);
第二种就是用 Articles rowv = (Articles)e.Item.DataItem;
            int articleId = rowv.Id;
