GridGroupingControl.ShowTreeLine set to true has no effect

[Günter Schwaiger]

grid.TableOptions.ShowTreeLines = true;
I have set this property to true, but no tree lines are shown. What have I done wrong?

At the moment, the tree lines are only shown for the second group level and higher but not for the first group level and also not for hierarchies.

We will be adding support for this in our codebase. It''s on our TODO list.
