Layout problem with column sizes on initial load

[Kevin Sonney]

I'm having layout problems with my grid at the initial load.  A couple of my columns will not auto size properly after they load their data, but as soon as I resize the browser window a bit the layout updates and everything is sized properly.  I've attached two screenshots to show the problem I'm seeing.  I've tried playing with the layout and some different properties, but I can't seem to get it to layout correctly after loading the data.

Here is my code:

<Grid Grid.Row="1" DataContext="{Binding Product, ElementName=mThis}" Grid.Column="1">
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>
            <Border CornerRadius="5" Background="{StaticResource InformationHeaderBrush}" Margin="3" Height="25">
                <Border Style="{StaticResource BorderGlossEffectStyle}" CornerRadius="5">
                    <TextBlock Text="Exchange Mail Stores" Style="{StaticResource TitleAreaTextStyle}"/>
                </Border>
            </Border>

            <telerik:RadGridView Grid.Row="1" ItemsSource="{Binding MailStores}" CanUserResizeColumns="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                                         CanUserReorderColumns="True" CanUserDeleteRows="False" RowIndicatorVisibility="Collapsed" IsFilteringAllowed="False"
                                         AutoGenerateColumns="False" IsReadOnly="True" CanUserSortColumns="True" CanUserSelect="False"
                                         AutoExpandGroups="True" telerik:StyleManager.Theme="Windows7" Margin="3 0 3 0">
                <telerik:RadGridView.GroupDescriptors>
                    <telerik:GroupDescriptor Member="Owner" DisplayContent="Server">
                        <telerik:GroupDescriptor.AggregateFunctions>
                            <telerik:CountFunction Caption="Total Mail Stores:"/>
                        </telerik:GroupDescriptor.AggregateFunctions>
                    </telerik:GroupDescriptor>
                </telerik:RadGridView.GroupDescriptors>
                <telerik:RadGridView.Columns>
                    <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}" Width="*"/>
                    <telerik:GridViewDataColumn Header="Server" DataMemberBinding="{Binding Owner}"/>
                    <telerik:GridViewDataColumn Header="File Size" DataMemberBinding="{Binding Size, Converter={StaticResource BytesToStringConverter}}"/>
                    <telerik:GridViewDataColumn Header="Mailboxes" DataMemberBinding="{Binding Mailboxes}" DataFormatString="N0"/>
                    <telerik:GridViewDataColumn Header="Items" DataMemberBinding="{Binding Items}" DataFormatString="N0"/>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>
        </Grid>
