LinqDataSource and EntityDataSource Data Source Controls

RadTreeList can be bound to all ASP 3.5 DataSource control types:

  • LinqDataSource

  • EntityDataSource

All you need to do is set the DataSourceID property of the TreeList to the ID of the Data Source control and the corresponding DataKeyNames and ParentDataKeyNames. Then you can use ASP.NET binding expressions (Eval or Bind)for the fields that will be visualized in the treelist's body.

Refer to the code snippet in the next paragraph:

<telerik:RadTreeList RenderMode="Lightweight" runat="server" ID="TreeList1" DataSourceID="LinqDataSource1"
    AllowPaging="true" PageSize="5" DataKeyNames="id" ParentDataKeyNames="parentId">
</telerik:RadTreeList>
<asp:LinqDataSource runat="server" ID="LinqDataSource1" ContextTypeName="TelerikSamplesDataContext"
    TableName="Links">
</asp:LinqDataSource>
