TreeView - Select

I'm going mad with this TTreeView-component!
My actual problem:
If I try to delete the selected Node, I get
an error message, if no one is selected.
Thats OK - I would do the same.
But I have found no proper way, to check out
IF there is a selected node.

Any Idea out there?

Thanks

Re:TreeView - Select

Did you try :

if (Assigned(TreeView1.Selected)) then begin
... do your stuff here ...
end;

if TreeView1.Selected = nil then Exit;

Simple as that, right ?
