Nested repeater with 3 levels

Discussion in 'ASP .Net' started by Eirik Eldorsen, Feb 3, 2005.

  1. Im trying to make a nested repeater with 3 levels. I've successfully created
    a nested repeater with 2 levels, but when adding the 3rd level I get an
    InvalidCastException. What am I doing wrong?


    Here is my code:


    <asp:Repeater id="level1Repeater" runat="server">
    <itemtemplate>
    <a href="#"><%# DataBinder.Eval(Container.DataItem, "Title") %></a>
    <br>
    <asp:repeater id="level2Repeater" runat="server" datasource='<%#
    ((DataRowView)Container.DataItem).Row.GetChildRows("L1L2") %>' >
    <itemtemplate>
    &nbsp;<a href="#"><%# DataBinder.Eval(Container.DataItem,
    "[\"Title\"]")%></a>
    <br>
    <asp:repeater id="level3Repeater" runat="server"
    datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("L2L3")
    %>' >
    <itemtemplate>
    &nbsp;&nbsp;<a href="#"><%#
    DataBinder.Eval(Container.DataItem, "[\"Title\"]")%><br></a>
    </itemtemplate>
    </asp:Repeater>
    </itemtemplate>
    </asp:Repeater>
    </itemtemplate>
    </asp:Repeater>



    Code Behind:

    private void BindWebsites()
    {
    level1Repeater.DataSource = Websites.GetAll();
    Page.DataBind();
    }

    public static DataTable GetAll()
    {
    .......
    ds.Relations.Add("L1L2", ds.Tables["WebsitesL1"].Columns["ID"],
    ds.Tables["WebsitesL2"].Columns["ParentID"]);
    ds.Relations.Add("L2L3", ds.Tables["WebsitesL2"].Columns["ID"],
    ds.Tables["WebsitesL3"].Columns["ParentID"]);

    return ds.Tables["WebsitesL1"];
    }

    Erik:
    Weird, everything looks good...While you shouln't have to, maybe if you move
    the nesting to the OnItemCommand event you'll figure out hte problem:

  3. Thank you!

    I moved the nesting to the OnItemDataBound event, and now everything works
    :-D
