Bug in TreeView.dll/ControlsEx.dll?

[specci48]

Hi guys,

if I run this piece of code (see attachment) on the desktop, the checked node2 jumps up and down every time I press the button "jump"...
If I run this code on the device, the both nodes still flip up and down, but the "checked"-information of node2 get's lost...

Is it a bug in the dll or in .Net CF?

Apparently the .Net CF treats differently checks by code and checks by clicking with the mouse (pen).
The checks that were done by the mouse are cleared when the node is removed from the tree, while the checks that were done by code do remain.

As you can see in my example, the node is checked by code and not by mouse/pen. According to your explanation the checked box should remain but in fact it gets cleared! Even I check the node by pen on the device, it gets cleared, too.

Here is a workaround for this issue (which is a .Net CF issue):
Make sure to use the updated ControlsEx library.

Sub Globals

End Sub

Sub App_Start
    Init
    FMain.Show
End Sub

Sub Init 
    Tree1.New1("FMain",5,5,230,230)
    Tree1.CheckBoxes = True
    node1.New1
    node1.Value = Tree1.AddNewNode("Node1")
    node1.Value = Tree1.AddNewNode("Node2")
    node1.Checked = True
End Sub

Sub BtnJump_Click
    node1.Value = Tree1.GetNode(1)
    Tree1.RemoveNodeAt(1)
    Tree1.InsertNode(0, node1.Value)
End Sub

Sub Tree1_AfterCheck
      If tree1.Action = "unknown" Then Return
      node1.Value = tree1.CheckedNode
      node1.Checked = node1.Checked
End Sub

Thanks Erel, that's the same solution I did implement for myself (so I did it right... )
I only wondered about your first answer which didn't expain the actual behavior.
