Hi,

I think you can handle nodemouseclick event. Like Follows:

 Private Sub treeView_NodeMouseClick(ByVal sender As Object, ByVal e As TreeNodeMouseClickEventArgs)
    If e.Node.Text.Equals("Add New") Then
      'add new custom;
    End If
    If e.Node.Text.Equals("View/Edit") Then
      'codes
    End If
  End Sub

Hope it helps.

Sincerely,
Vin Jin

Answer 2

Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As TreeNodeMouseClickEventArgs)

If e.Node.Name.Equals("CusAddNew") Then

Dim frm As New NewCustomer

frm.MdiParent = DIS

frm.Show()

End If

This is the code i inserted and nothing happens when the node is clicked ... I changed it a little form e.Node.Text.Equals to e.Node.Name.Equals

Sub isn't handling any event, you're missing the Handles part.

Private Sub treeView_NodeMouseClick(ByVal sender As Object, ByVal e As TreeNodeMouseClickEventArgs)

Should be

Private Sub treeView_NodeMouseClick(ByVal sender As Object, ByVal e As TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick

 

However, if you're adding nodes in Run time, you'll have to add handler in run time as well

AddHandler treeNodeToBeAdded.MouseClick, AddressOf treeView_NodeMouseClick
