Hi all!

I use TreeView in my form and I want to give users ability to rename nodes either by clicking the node or by pressing appropriate button on my form.
I also use "BeforeLabelEdit" method of the TreeView to ensure that the clicked node is changeble before user can rename it. This works fine when I click the node but when I press my button, "BeforeLabelEdit" method just isn't called. I use the following syntax in my button's Click Event:
MyForm.MyTreeView.StartLabelEdit

I tried to use another syntaxes:
MyForm.MyTreeView.BeforeLabelEdit
MyForm.MyTreeView.StartLabelEdit
or
MyForm.MyTreeView.Click
or
MyForm.MyTreeView.NodeClick(MyForm.MyTreeView.SelectedItem)

but result is the same. It doesn't work.

Maybe who knows what's the trick ?
