DataSet to fit DataGrid

Hi,

I load a dataset into a datagrid from XML file. The file loads correctly but its display doesn't completely fit the datagrid: there is a grey space on the right. I want to get rid of that grey space so that the data columns are expanded to use all of the space available. The first column, where you select the rows, shouldn't be expanded. How do I achieve this? I looked into DataGridTableStyle class but I couldn't figure out how to use it; it seems to repeat the same methods from DataGrid class. Thanks for your help.

 Private Sub Form1_Load(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles MyBase.Load
        LoadXMLData()
    End Sub    

    Private Sub LoadXMLData()
        ds = New DataSet
        ds.ReadXml("c:\rules.xml")
        xmlRules.SetDataBinding(ds, "rule")
        tbl = ds.Tables(0)
    End Sub

XML file example
========

<?xml version="1.0"?>
<folder-rules>
  <rule>
    <variable>m_EDSTYPCD</variable>
    <value>P</value>
    <destination>Facilities</destination>
    <default>Blah</default>
    <function>PrintGreeting</function>
    <param1>Hello</param1>
    <param2>World</param2>
    <level>1</level>
  </rule>
</folder-rules>

1) Define a DataGridTableStyle
2) Specify each column type as DataGridTextBoxColumn, DataGridBoolColumn, etc.
3) Define the column widths as a percent of ClientSize.Width for the entire DataGrid.

Set column widths like this:

Column 1:  DataGrid1.ClientSize.Width * .25
Column 2:  DataGrid1.ClientSize.Width * .25
Column 3:  DataGrid1.ClientSize.Width * .25
Column 4:  DataGrid1.ClientSize.Width * .10
Column 5:  DataGrid1.ClientSize.Width * .5
Column 6:  DataGrid1.ClientSize.Width * .20

The total needs to be 1.00 or 100% of the width.
