I have a treeview with two nodes..I m showing the contextmenu when the user clicks on any portion of treeview ....

Public Class Form2

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try

            Dim N As New TreeNode()
            Me.TreeViewCategories.Nodes.Clear()
            With Me.TreeViewCategories.Nodes
                N = .Add("", "Main", 0)
                N.Nodes.Add("", "First Child", 0)
                N.Nodes.Add("", "Second Child", 0)
            End With
            TreeViewCategories.ExpandAll()

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub


    Private Sub TreeViewCategories_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeViewCategories.MouseDown
        If e.Button = Windows.Forms.MouseButtons.Right Then
