A root node is interpreted by RadTreeView as any node with a DataFieldParentID of null or empty default value.
I have a hierarchy which is cut from a larger hierarchy and as a result, the Parent value (a Guid in this case) of the nodes I want to root are set to specific values. As I am binding to an ObjectDataSource I simply overwrite the Parent Guid for the root nodes in my BL with Guid.Empty.
However it would be nice if there were some way to specify the root value to hook on to so this fudge would not be necessary.
One alternative I tried was to create a static node with a value of the specific root Guid I want to hook on to. However I found that even with AppendDataBoundItems enabled the bound data does not hook on to the single, static, root node.
Has anyone else shared my experience?
Thanks

Yup, it'd be great if the heirachical bound controls had a 'root node ID' property you could specifiy, for when your binding to a subset of some heirachical data.

Up Up Up :)
In fact, I have a huge TreeView representing hierarchy level in my company. It's very usefull, like this I can select a level very easily.
And sometimes, I would like to display only a small part of this hierarchy... It would be so great to say:
RootParentID = 17
And automatically, we display only all the elements from where the parentID is 17.
If you have another way to do it... I would be happy to learn it :)
Thank you

Can this be done yet?
I can get my RADTreeview to work when the ParentID = 0 but the RADMenu doesn't. And in the case of the RADMenu, sometimes I am working from a different root value anyway. This seems like a really simple idea. Is it ever going to happen?

I also would like this functionality and am surprised after all these years it hasn't been incorporated yet.
