Define the columns explictily in your XAML and set AutoGenerateColumns to false:

<DataGrid AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="..." Binding="{Binding Column1}" Width="1*" />
        <DataGridTextColumn Header="..." Binding="{Binding Column2}" Width="2*" />
    </DataGrid.Columns>
</DataGrid>

Or handle the AutoGeneratingColumn event:

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    //...
    e.Column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
}
