AutoSizeDropDownToBestFit is not working when i have 3 rows in the drop down list. Scroll bars appear with i have 3 rows, and when i only 2 rows it autosize the width of the dropdown.

[Code ]

        Dim TransData As DataTable = New DataTable
        TransData.Columns.Add("Index")
        TransData.Columns.Add("Type")
        TransData.Rows.Add("0", "-- Select --")
        TransData.Rows.Add("SEA", "Ship by Sea")
        TransData.Rows.Add("AIR", "Ship by Air")
        TransData.Rows.Add("VOR", "VOR by Air")

        TransportRadMultiColumnComboBox.DataSource = TransData
        TransportRadMultiColumnComboBox.DisplayMember = "Type"
        TransportRadMultiColumnComboBox.ValueMember = "Index"
        TransportRadMultiColumnComboBox.Columns(0).IsVisible = False
        TransportRadMultiColumnComboBox.Columns(1).HeaderText = "Transport"
        TransportRadMultiColumnComboBox.AutoSizeDropDownToBestFit = True

[Works when i have only 2 rows in my DataTable]
