Hello,

I have just upgraded my telerik components that I use inside our sitefinity custom controls so that I can use RadDropDownTree.

I have coded it as it is done on the demos webpage resources but only using a DataTable as DataSource .

The objects works just fine but the problem is although it recognizes and orders the elements in the correct hierarchy,

The child items does not get indented so instead of looking like this

+GrandParent1

 -GrandParent2

     +Parent1

     -Parent2

         +Child1
          +Child2

they look like this

+GrandParent1

-GrandParent2

 +Parent1

 -Parent2

 +Child1

 +Child2

There is no property in the documents and in the public properties about the “indentation of child nodes” as far as I can see.
Shouldn't indentation be the default behaviour of a dropdown tree?
I mean it's almost the whole purpose of a dropdown tree instead of a DropDownList.

Am I missing something? Or is there something missing in the documentation about this, or is there a bug?

IBelow are my .ascx and .cs files so that you can see for yourselves that it is not different than the example documentation.

Thank you..
