TableLayoutPanel in VB.Net 2005

[watagal]

I am trying to add a TableLayoutPanel (programatically). Here's what I have so far:

Private Sub drawTableLayoutPanel()
        Dim iColumns As Integer = uxColumnsTbar.Maximum  ' Horizontal Trackbar
        Dim iRows As Integer = uxRowsTbar.Maximum        ' Vertical Trackbar
'
        Dim oTLP As New TableLayoutPanel
        oTLP.Location = New Point(0, 0)
        oTLP.Size = New Size(500, 200)
        oTLP.AutoScroll = True
        oTLP.AutoSizeMode = Windows.Forms.AutoSizeMode.GrowAndShrink
        oTLP.GrowStyle = TableLayoutPanelGrowStyle.AddRows
        oTLP.CellBorderStyle = TableLayoutPanelCellBorderStyle.Inset
        '
        oTLP.ColumnCount = iColumns
        For c As Integer = 0 To (iColumns - 1)
            oTLP.ColumnStyles(c).SizeType = SizeType.Absolute  ' Errors HERE with c=0
            oTLP.ColumnStyles(c).Width = (1 / iColumns)
        Next
        '
        oTLP.RowCount = iRows
        For r As Integer = 0 To (iRows - 1)
            oTLP.RowStyles(r).SizeType = SizeType.Absolute
            oTLP.RowStyles(r).Height = (1 / iRows)
        Next
        '
        oTLP.Update()
    End Sub

The error I get is:

System.ArgumentOutOfRangeException was unhandled
Message="Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"

Which collection are they referring to? iColumns=6 and iRows=4 - this has been verified. Thanks, Karen Nooobie to OOP and VB.Net 2005

Well, I've haven't used the TableLayoutPanel yet, but it looks like the TableLayoutPanel.ColumnStyles collection is empty. Just because you set the ColumnCount to whatever, doesn't mean that there are any ColumnStyle objects added to the ColumnStylesCollection your trying to index.

For c As Integer = 0 To (iColumns - 1)
Dim newColStyle = New ColumnStyle(SizeType.Absolute, 1/iColumns)
Next

Thanks Dave, that got me past the error message. I still don't get a TableLayoutPanel Control on my at runtime, but I'll post a new message with an appropriate subject title. Thanks again, Karen Nooobie to OOP and VB.Net 2005
