Can't See Data in TreeView or ListBox when using User Defined Class

[Balarao]

Dear All,

I have created a ZipCode Class:

Public Class ZipCodeClass

Private mZipTree as TreeView

Public ReadOnly Property ZipCodeTreeView() As TreeView
Get
If mZipCodeTreeView Is Nothing Then
CreateZipTree()
End If

Return mZipCodeTreeView
End Get
End Property


The CreateZipTree() is a private sub of the ZipCode Class that places all the Zip Code in the mZipCodeTreeView nodes. This Work well.

The problem is when I call the property in my program:

Dim Zip as ZipCodeClass
tvwZipCode = Zip.ZipCodeTreeView

My tvwZipCode DOES NOT DISPLAY ANY NODES that the ZipCodeTreeView passes but the values of their properties and methods are the same. I tried using the method

tvwZipCode.GetNodeCount(True)
tvwZipCode.GetNodeCount(False)

and got the same number of nodes on both methods as in the ZipCodeTreeView.

tvwZipCode is a TreeView control I created using the VB.NET ToolBar.

Please help me find my nodes.

Thank you so much for your help.

God bless,

Balarao

Hi Chrissie1,

Thank you for responding.

i tried what you suggested "tvwzipcode.nodes(0).count"

An error occurred: Count is not a member of the 'System.Windows.Forms.TreeNode'

What do you mean by trying this code?

I tried using tvwzipcode.Refresh() after get the nodes in the class. Still doesn't work.

Please help.
