Duplicate Band Names
posted

Hi,

I'm having problems with Level 2 of the tree and I think it may be down the the band name...

I'm working with a tree and it's datasource is a collection of objects.  Each object can have a collection of child object of the same type so it's a tree of objects with any number of levels.

Class clsGroup

 - Public Property Children As List (Of clsGroup)

When I pass the list of top level clsGroup to the tree as a datasource the list is shown as expected.  Within the BeforeExpand I load any Child Groups which works as expected and level 1 is shown.  The problem is nothing appear when I try to expand level 1 into level 2.  I'm wondering if it because the band name will be the same (Children)?

Am I making sense?!?!

Thanks

    I can't think of a reason why the band name would have anything to do with this. It sounds like the clsGroup list is not getting populated for the level 1 members, thus leaving no data to display for level 2. You should put a breakpoint in the method that adds members to the list and then maybe you will be able to determine why nothing is getting added.
