TreeView ScrollBar bug

I have a treeview in the winform application....

I added a node to it and reduced the width of the treeview such that the horizontal scroll comes...

then i deleted the added 开发者_运维问答node.

When i increase the treeview width the scroll comes...

But the scroll should not come..

What is the solution for this condition?

Sounds like a threading issue. Does your code contain any Application.DoEvents()? Do you update the TreeView from the GUI thread? Please show some code.

Use a non-standard 3rd party treeview. The default one has bugs far worse than this.
