Question How to setup a simple checkedlistbox app.

[newguy]

Hi all, I have a checkedlistbox, and I want to have the value for each checked box to sent to a textbox.

Public Class Form1

    Dim chklistbox1 As New BetterCheckedListBox

    Public Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
        Select Case ListBox1.SelectedIndex
            Case 0                                                                              
                GroupBox1.Controls.Clear()
                GroupBox2.Controls.Clear()
                With chklistbox1
                    .BackColor = Color.LightBlue
                    .Dock = DockStyle.Fill
                    .ThreeDCheckBoxes = True
                    .Sorted = False
                    .BorderStyle = BorderStyle.Fixed3D
                    .CheckOnClick = True
                    .Items.Add("1", False)
                    .Items.Add("2", False)
                    .Items.Add("3", False)
                End With
                GroupBox2.Controls.Add(chklistbox1)
                AddHandler chklistbox1.ItemCheck, AddressOf chklistbox1_itemCheck
                
               
        End Select
    End Sub
    
    Private Sub chklistbox1_itemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs)
        Dim itm As String = chklistbox1.SelectedItem
        If e.NewValue = CheckState.Checked Then
            Comments.Text = itm
        Else
            If e.NewValue = CheckState.Unchecked Then
                Comments.Text = ""
            End If
        End If
    End Sub
    End Class

So I basically want the "1", "2" or "3" to show up in the textbox the cooresponding checkbox checked.

But I keep getting a InvalidCastException - unable to cast object of type system.eventArgs to system.windows.form.itemsCheckedArgs.

Any ideas?
