Description Claudia Baier 2018-03-16 10:14:14 EDT 
I implement TDBTree with checkboxes. The DBTree has around 2000 shapes in 4 hierarchical level.
First all nodes are Expanded := False.
I use the OnClickShape event and it works fine.
Until I expanded and scroll in tree for much times,
then the TTreeNodeShape in OnClickShape event is the wrong node!
This happens undeterminated.

With TeeChart 8.07: First the node text have to be clicked then the OnClickShape event
fires for the correct node. But with the new version of TeeChart, it do not work again.

With the checked-shapes my application generate a sql-query.
So the wrong behavior in unterminated cases is a grave error in my application.

What can I do?

Hello Steema-Team,

regarding my still unresolved error.
I found a note in your support-forums, by searching 'OnClickShape'.
This note (titled by 'OnClickShape Bug in Teetree', posted by Roland) describe a problem, 
that seems to by like my problem.

The solution posted by Tom was to change a statement the file 'TeeTree.pas'.
But i do not found this file on my system. 

Please help me. We need it very urgently.

Best regards

The problem occurs using latest TeeChart Pro VCL/FMX 2018.25. To reproduce the problem is necessary following the steps below: 

1. open the node <Gmd u. außerhalb RLP>

   (about 2000 childs are expanded)

2. scroll und check some boxes on this childs-tree-part

3. open another node below, for examble <Altj.u. 15 b. 66 u.m.>

4. scroll und check some boxes on this childs-tree-part

5. close the node <Altj.u. 15 b. 66 u.m.>

6. scroll up

7. close the node <Gmd u. außerhalb RLP>

8. scroll up

9. open the node <Kreise u.außerh. RLP>

10. try to check some children.

Note you should check only some children notes.
