Hi guys, this has probably already been answered, but here goes

I have created my entity using LLBL and am trying to bind it as a datasource to a treeview control on a web form in Visual Studio. Here's the basis of my asp code <body>

<form id="form1" runat="server"> <asp:TreeView ID="TreeView1" runat="server" DataSourceID="LLBLGenProDataSource1"> </asp:TreeView> </form>

</body> <llblgenpro:LLBLGenProDataSource2 ID="LLBLGenProDataSource1" runat="server"> </llblgenpro:LLBLGenProDataSource2>

when I run it, I keep getting the errormessage - The 'DataSource' property cannot be set declaratively.

What am I doing wrong here...?

Thanks in advance

I think you are missing some properties in the treeView. Also, the LLBLGenProDatasource is not pointing to any factory. Try to setup it in design view to facilitate this.

Weird. As you are setting DataSourceID, not DataSource property. Do you have the same problem if you bind to another object (other classes or an ObjectDataSource) ?
