UserControl on TableLayoutPanel Sizing Issue

[Borvik]

I have a UserControl that has a TableLayoutPanel on it. That panel has only one row and two columns - a NumericUpDown control in the first, and a ComboBox in the second.

Whenever the items in the combobox get updated the combobox is resized according to the following routine:

    Private Sub ResizeCombo()
        Dim g As Graphics = cboUnits.CreateGraphics
        Dim maxWidth As Integer
        For Each obj As Object In cboUnits.Items
            Dim s As String = obj.ToString
            Dim intWidth As Integer

            intWidth = CInt(g.MeasureString(s, cboUnits.Font).Width)
            maxWidth = Math.Max(maxWidth, intWidth)
        Next
        cboUnits.Width = maxWidth + SystemInformation.VerticalScrollBarWidth
        Me.Invalidate()
    End Sub

The column the ComboBox is in is also set to auto-size. The NumericUpDown column is set for a percentage and both controls have their anchor set to "Left, Right".

The above describe UserControl works fine - except when itself is placed within a TableLayoutPanel, at which point the size gets reduced to 0,0 and I am unable to resize it.

Any ideas on what is causing this or how to get around it?

Thanks.

Doggone it - the UserControl's AutoSize property was set to True - that was what was causing it.
