I am missing something, just not sure what.
I am filling a listbox using a dataset.  There is 1 record in the table and when I do message boxes to show if there are any items in the listbox, it shows that there is the 1 item, but the item does not show in the list box.
What am I doing wrong???
Below I use messageboxes to check that there is an item.

Private Sub FillTaskList(Optional ByVal bStartUp As Boolean = False)

        Dim cT As New cTasks(ConnectionString)

 

        cT.FillList(Me.lstTasks)

        MessageBox.Show(Me.lstTasks.Items.Count)

        If bStartUp Then

            cT.SetupTaskLUGrid(Me.fpGrdTasks)

            MessageBox.Show(Me.lstTasks.Items.Count)

            Me.lstTasks.SelectedIndex = -1

            MessageBox.Show(Me.lstTasks.Items.Count)

        End If

    End Sub

 

I fill the list using

Private Function SQLCombo() As String

        Dim str As String

 

        str = "SELECT TaskID, " _

        & " TaskName " _

        & " FROM TasksLU " _

        & " ORDER BY TaskName"

 

        Return str

 

    End Function

 

 

 

 

    Public Sub FillList(ByVal cnt As ListBox)

        Dim ds As New DataSet

 

        If DatabaseToUse() = BizObjs.DBType.Access Then

            'Access Database

            Dim dc As New OleDb.OleDbConnection(ConnectionString)

            Dim da As New OleDb.OleDbDataAdapter(SQLCombo, dc)

 

            Try

 

                da.Fill(ds)

                dc.Close()

                cnt.DataSource = ds.Tables(0)

                cnt.DisplayMember = "TaskName"

                cnt.ValueMember = "TaskID"

 

            Catch ex As Exception

 

                MessageBox.Show(ex.Message)

                ''Throw ex

 

            Finally

                dc.Close()

                da.Dispose()

            End Try

        End If

 

    End Sub

This is a windows form VB 2008 net app and the listbox does not have a databind property.
Thanks
