How to arrange controls vertically? [VS 2010, WPF]

Mar 22, 2010 at 7:13 AM

I have following markup. There're two groups. In one of the groups there's a Button and two TextBoxes. However, with standard markup, these TextBoxes are horizontally arranged. How to arrange them vertically?

 

<r:RibbonTab Label="Load">

                <r:RibbonGroup>
                    <r:RibbonGroup.Command>
                        <r:RibbonCommand LabelTitle="Offload" />
                    </r:RibbonGroup.Command>
                    <r:RibbonButton Command="{StaticResource GetOffloadDataCommand}" />
                    <r:RibbonControlGroup>
                        <r:RibbonTextBox x:Name="rxOffloadMonth" />
                        <r:RibbonTextBox x:Name="rxOffloadYear" />
                    </r:RibbonControlGroup>
                </r:RibbonGroup>

                <r:RibbonGroup>
                    <r:RibbonGroup.Command>
                        <r:RibbonCommand LabelTitle="SP" />
                    </r:RibbonGroup.Command>
                    <r:RibbonButton Command="{StaticResource GetSpDataCommand}" />
                </r:RibbonGroup>

</r:RibbonTab>
