            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="auto"/>
            </Grid.RowDefinitions>


                <ribbon:Ribbon x:Name="Ribbon">

                    <ribbon:RibbonTab x:Name="HomeTab" 
                                  Header="Home">
                        <ribbon:RibbonGroup x:Name="Group1" 
                                        Header="Refresh">
                            <ribbon:RibbonButton x:Name="BtmRefresh"
                                             LargeImageSource="Images\refresh.png"
                                             Label="Refresh" Margin="25,0,30,0" Click="BtmRefresh_Click" />
                        </ribbon:RibbonGroup>
                    </ribbon:RibbonTab>
                </ribbon:Ribbon>


            <StackPanel Name="PanelDataGrid" Height="Auto" >

                    <DataGrid  AutoGenerateColumns="False" Margin="0,138,0,0" Name="dataGrid" Height="Auto" ItemsSource="{Binding}"  SelectionUnit="Cell"   AlternatingRowBackground="#FFDFE9F5"

                        </DataGrid.Background>
                        <DataGrid.Columns >

                            <DataGridTextColumn Binding="{Binding Path=Job_Num}"  Header="Job Nº" IsReadOnly="True" Width="1*" />
                            <DataGridTextColumn Binding="{Binding Path=Product_Code}" IsReadOnly="True" Header="Product" Width="1*" />
    </DataGrid.Columns>
                    </DataGrid>

  • I would suggest posting a sample of your xaml code to get a better and more specific answer – Joel Briggs May 20 '11 at 14:21

    Can you post your XAML code with the ViewBox? – Rachel May 20 '11 at 14:57

  • @Rachel and @msarchet when I add Viewbox Stretch="UniformToFill" Margin="5,5,5,5" It is stretching everything However my columns dissapear and I just have my 1st column on my grid. – CPM May 20 '11 at 15:21

Add StretchDirection="Both" to your ViewBox and it should work

// Will Stretch it and keep the ratio the same
<Viewbox Stretch="Uniform" StretchDirection="Both">


// Will Stretch it to fill full screen regardless of ratio
<Viewbox Stretch="Fill" StretchDirection="Both">

I'm just going to go out and guess that you need to anchor your viewbox to the sides of the control. This is the margin property.

Your ViewBox should have something that looks like Margin=5,5,5,5 in it's XAML.
