Body
I'm using a <code>CollectionViewSource</code> to group my data. In my data, I have <code>Property1</code> and <code>Property2</code> that I'm needing to group on. The only stipulation is that I don't want sub-groups of another group. So, when I group by these two properties, I don't want to have it so that <code>Property2</code> because a subgroup of <code>Property1</code>'s group. The reason why I want this is because I need to have a header that shows the following information: Header: <pre><code><TextBlock.Text> <MultiBinding StringFormat="Property1: {0}, Property2: {1}"> <Binding Path="Property1"/> <Binding Path="Property2"/> </MultiBinding> </TextBlock.Text> </code></pre> I've tried this with my CollectionViewSource but was not able to "combine" the group and subgroup together: <pre><code><CollectionViewSource x:Key="myKey" Source="{Binding myDataSource}"> <CollectionViewSource.GroupDescriptions> <PropertyGroupDescription PropertyName="Property1" /> <PropertyGroupDescription PropertyName="Property2" /> </CollectionViewSource.GroupDescriptions> </CollectionViewSource> </code></pre> Is it possible to group two properties together? Something like below? <pre><code><CollectionViewSource x:Key="myKey" Source="{Binding myDataSource}"> <CollectionViewSource.GroupDescriptions> <PropertyGroupDescription PropertyName="Property1,Property2" /> </CollectionViewSource.GroupDescriptions> </CollectionViewSource> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
