I found a workaround.
The "bug" here is that since the treelist is initially collapsed, the width is determined by the total width of the Level 1 tree entries.
I padded 's into the common.config file for first tree link item.
It would be nice if you could expose property on the TreeList control. In the meantime, this works nicely.
Thanks for the feedback.
