嵌套字典到嵌套转发器 asp.net c#

我正在制作一个 asp.page，它将显示有关公司资产的分层信息。

为了获取数据，我使用了 lambda 表达式：

            FASAssetInfoDataContext fasInfo = new FASAssetInfoDataContext();
        var data = from g in fasInfo.Asset_Informations
                          where g.Department.Substring(0, 3) == p
                          select g;
        Dictionary<string, Dictionary<string, List<info>>> branch = data.GroupBy(e => e.Location)
            .ToDictionary(g => g.Key,
            g => g.GroupBy(gl => gl.G_L_Asset_Acct_No)
                .ToDictionary(gl => gl.Key,
                gl => gl.Select(s => new info
                {
                    acqDate = s.Acquisition_Date,
                    asstNo = s.Co_Asset_Number,
                    classInfo = s.Class,
                    description = s.Description,
                    mfgSerialNo = s.Mfg_Serial_No,
                    deprThisRun = s.Depr_This_Run__Int_,
                    AcqValue = s.Acquisition_Value__Int_,
                    currentAccDepr = s.Current_Accum_Depr__Int_,
                    estLife = s.Est_Life__YYMM___Int_,
                    inServiceDate = s.Placed_In_Service_Date__Int_,
                    netBookValue = s.Current_Net_Book_Value__Int_,
                    oldAcqValue = s.Acquisition_Value__Tax_
                }).ToList()));

所以我现在有一组嵌套的字典，末尾有一个信息列表。我的问题是如何最好地在页面本身上显示这些信息？我可以达到第一级，但一直在努力让嵌套中继器正常运行。如果有更好的控件可以使用，我洗耳恭听:)

Thanks,

如果您确实需要使用嵌套中继器，这是可能的，但让它工作并不是特别明显。以下内容可行（为简洁起见，进行了简化）：

<asp:Repeater id="level1" OnItemDataBound="level1_ItemDataBound" ...>
  <ItemTemplate>
    <asp:Repeater id="level2" OnItemDataBound="level2_ItemDataBound" ...>
      <ItemTemplate>
        <asp:Repeater id="level3" OnItemDataBound="level3_ItemDataBound" ...>
        </asp:Repeater>
      </ItemTemplate>
    </asp:Repeater>
  </ItemTemplate>
</asp:Repeater>

背后代码：

protected void Page_Load(object sender, EventArgs e)
{
    Dictionary<string, Dictionary<string, List<info>>> branch = ...;
    level1.DataSource = branch;
    level1.DataBind();
}

protected void level1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    Dictionary<string, List<info>> data = (Dictionary<string, List<info>>)e.Item.DataItem;
    Repeater level2 = e.Item.FindControl("level2") as Repeater;
    level2.DataSource = data;
    level2.DataBind();
}

protected void level2_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    List<info> data = (List<info>)e.Item.DataItem;
    Repeater level3 = e.Item.FindControl("level3") as Repeater;
    level3.DataSource = data;
    level3.DataBind();
}

protected void level3_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
   // Bind properties from info elements in List<info> here
}
