Hi,

I think it's simple task and I could not figure it out easily ... VB6 treeview used to have a expanded imageindex so it's easy ...

now, in VB.NET, I have folders and items in treeview, for item, I can set the imageindex = selectimageindex to make sure when the item is selected the image will not change.

but there is no way to set the folder easily ... I want to keep the folder's image as "open folder" image regardless if it's selected or not as long as it's expanded and use "close folder" image regardless if it's selected or not as long as it's collapsed.

Could someone help me on this?

Thanks!
John
 
Hello John,

We can listen to the TreeView's AfterExpand and AfterCollapse event, in the
event handle, we set the node's image respectively. The following codes
work fine in my side,

Private Sub TreeView1_AfterExpand(ByVal sender As System.Object, ByVal
e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterExpand
e.Node.ImageIndex = 3
End Sub

Private Sub TreeView1_AfterCollapse(ByVal sender As System.Object,
ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles
TreeView1.AfterCollapse
e.Node.ImageIndex = 0
End Sub

Please have a try and let me know if this helps! If you have any future
questions or concerns, please do not hesitate to let me know.
