[2005] Tree view nodes and context menu

[Gero]

I have a tree view with items which each have a ContextMenuStrip. How do i know on which tree node the user activated the context menu when handling events like clicks on items in the context menu?

I was intrigued by your question so I had a wee look. The SourceControl property of the menu is no use because that refers to the TreeView containing the node. I don't know if there's a better way but this is what I came up with:

Private Sub TreeView1_MouseDown(ByVal sender As Object, _
                                ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseDown
    If e.Button = Windows.Forms.MouseButtons.Right Then
        Me.ContextMenuStrip1.Tag = Me.TreeView1.GetNodeAt(e.Location)
    End If
End Sub
 
Private Sub Item1ToolStripMenuItem_Click(ByVal sender As System.Object, _
                                         ByVal e As System.EventArgs) Handles Item1ToolStripMenuItem.Click
    Dim sourceNode As TreeNode = TryCast(Me.ContextMenuStrip1.Tag, TreeNode)
 
    If sourceNode IsNot Nothing Then
        MessageBox.Show("Source node: " & sourceNode.Text)
    End If
End Sub
