I have a treeview that is coming from a dataset. When I update or delete the data I need to refresh the treeview and keep the setting of the treeview - if it is expanded.

Thanks in advance.

I figured it out.
At the TreeView1_AfterSelect
Dim node As System.Windows.Forms.TreeNode
node = TreeView1.SelectedNode
i = node.Index
j = node.Parent.Index

The reload the treeview with the dataset then do the following:

TreeView1.Nodes(i).Expand()
TreeView1.Nodes(i).Nodes(j).Expand()

OOPsies : Let me correct one thing:
At the TreeView1_AfterSelect
Dim node As System.Windows.Forms.TreeNode
node = TreeView1.SelectedNode
i = node.Parent.Parent.Index
j = node.Parent.Index

Sorry about the error.
