Here we can see a part of my tree:

a

|- b
|- c
|- d
|- e


I'm expanding d:

a
|- b
|- c
|- d
|  |- f
|- e

I'm expanding f:

a
|- b
|- c
|- d
|  |- f
|  |  |- g
|- e


Now I'm expandng c:


a
|- b
|- c
|  |- h
|  |  |- i
|- d
|  |- f
|- e

f is no more expanded. Instead of f, h was expanded and I see i under h instead of g under f.

All branches are bound with needdatasource events: NeedDataSource or ChildItemsDataBind for children.

The only way to fix it is:

on Page_Load event: to find all items connected to ExpandedIndexes and save their DataKeys
on ItemDataBound set item.Expanded to true/false

But when I set item.Expanded to false, it is set up back to true.

I must remove its from ExpandedIndexes manually, using Page_PreRender...

Why

item.Expanded = false

doesn't do that?

Hello Lukasz,

We were able to reproduce the behavior you are talking about and we consider this as a bug in our current RadTreeList implementation. We have forwarded this to our developer team for further investigation.

We apologize for the inconvenience caused.

No problem for me - I found the solution ;)

Something is wrong with selected items after expanding too.

Thx for reply.
