Hello,

I have a table with Guid as Primary key and using ParentID hierarchy. The TreeView doesn't seem to like/render the child nodes....

<telerik:RadTreeView ID="RadTreeView1" Runat="server"   
        DataSourceID="LinqDataSource1" DataFieldID="ItemID"   
        DataFieldParentID="ParentID" DataTextField="Title" >  
   
        <CollapseAnimation Type="OutQuint" Duration="100"></CollapseAnimation> 
        <ExpandAnimation Duration="100"></ExpandAnimation> 
</telerik:RadTreeView> 

My ItemID and ParentID are of type Guid like : b87f0a3f-05d7-442a-8f6b-1496b7a89c38. Forr root nodes, the ParentID = null.

Thanks,

Michael

Hi mfrimu,

RadTreeView needs Guid.Empty for the root items instead of null.

Thanks,

While waiting for your answer I tried changing the Guid fields to standard int64 identity fields, and for some reason, the TreeView does not display the children properly, I get the whole list of items as if all items were at the root level.

Check my screen grabs:
