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> <a href="#"><%# DataBinder.Eval(Container.DataItem, "[\"Title\"]")%></a> <br> <asp:repeater id="level3Repeater" runat="server" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("L2L3") %>' > <itemtemplate> <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"]; } -- Eirik Eldorsen
Thank you!
I moved the nesting to the OnItemDataBound event, and now everything works :-D "Karl Seguin" <karl REMOVE @ REMOVE openmymind REMOVEMETOO .
