Expanding nodes in TUniTreeview programmatically?

[tcoates]

In our program we have a treeview (TUniTreeview) and the contents of which are added when the program loads....

 

  tempNode2 := NavTree.Items.Add(nil, 'Recordings');
  tempNode2.ImageIndex := 1; tempNode2.SelectedIndex := 1;
 

but ... only want certain nodes in the treeview to appear in expanded form, but not others when the page is initially displayed to the user. ie .. I tried something like...

 

  NavTree.Items[1].Expand(True)

 

but that did not work.

 

Can someone give me a hand on what to do here? Thanks.

Hi,

Can you make a simple testcase for this?!

 

Best regards,

Attached demo program.

 

The demo program I created as built in steps. First I populate the treeview via button onclick event, and ti worked as expected. Then I added code to populate treeview during the form create event and that is when node 'B' does not expand.

Only one item can be expanded inside a timer.

I mean you can't expand more than one node inside a timer event
