Nested databinding question

[Joel]

Hey everyone,

I'm trying to databind some elements to data to the Panel Bar in the following format:

• Top Category 1
  
  • sub cat 1
  • sub cat 2
• sub cat 1
• sub cat 2
• Top Category 2

But I haven't been able to find any resources in the help docs.  Could anyone point me in the right direction?  This is what I have so far:

                    <telerik:RadPanelBar ID="rpbMainNav" runat="server" DataTextField="Name" DataValueField="Id" OnItemDataBound="rpbMainNav_ItemDataBound" Skin="Web20" ExpandMode="SingleExpandedItem" PersistStateInCookie="True">
                        <CollapseAnimation Duration="100" Type="None" />
                        <ExpandAnimation Duration="100" Type="Linear" />                                               
                        <ItemTemplate>
                             <%# BuildStoreList(DataBinder.Eval(Container.DataItem, "Id")) %>
                        </ItemTemplate>
                    </telerik:RadPanelBar>

Thanks in advance!

Hi Joel,

You can establish hierarchy through ID to ParentID relationship using:

DataFieldID - The name of the DataColumn holding the ID value.
DataFieldParentID - The name of the DataColumn holding the ParentID value. The id of the root items should be null.

I suggest you review the following online resources: Hierarchical Data Binding and Binding to Hierarchical DataSource Components
