  I want to the same level nodes are closed.

  What do you want the other nodes to do From what level ( that is, below the selected node, or across the entire tree )

  Please be more clear.

  You have a tree with nodes which in turn have child nodes. Now when you click a node, what exactly should happen

  Anyway check the code below. I have TreeView which is like this:

  Root

  C1

  c11

  c22

  C2

  c21

  c22

  If you have multiple levels and get the parent node of the selected node and collapse all the nodes under the parent of the selected node.Anything more needed, please feel free to contact me.

  Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
  'to close all the nodes under the selected node
  If Not IsNothing(e.Node.Parent) Then
  ' to close all the nodes under the selected node
  If e.Node.IsExpanded Then e.Node.Collapse(True)
  End If

  ' this is to collpase the all the nodes in the same level
  If Not IsNothing(e.Node.Parent) Then
  If TreeView1.Nodes.Count > 0 Then
  Dim iLoop As Integer
  For iLoop = 0 To TreeView1.Nodes.Count - 1
  If TreeView1.Nodes(iLoop).IsExpanded Then
  TreeView1.Nodes(iLoop).Collapse(True)
  End If
  Next

  End If
  End If

  
  End Sub
