    <p>Silverlight System where a asp User Pharmacy has a linked table For thier Inventory. I am trying to display this inventory in a list (datagrid) and provide them a way in which to edit and add items to the list through a datagrid. Currently I am struggling with the binding of this dataform... Xaml provided, any help?</p> <pre><code>&lt;Grid x:Name="LayoutRoot"&gt; &lt;Button Content="Save Changes" Height="52" Width="103" Name="SaveChangesButton" VerticalAlignment="Top" Click="SaveChanges" ContentTemplate="{Binding}" Margin="169,309,367,0" /&gt;

    1. COWelcome to StackOverflow! Can you be more specific with what "struggling with binding" means. This is a lot of markup to pore over without a clear indication of what specific problems you're having.

    2. COSpecifically binding the dataform and datagrid to a Inventory for the logged in Pharmacy. I am successfully getting the correct Pharmacy through a filter descriptor. However It seems to bind the dataform to the domainservice for the pharmacy and does not allow it to drill down to Inventory (which is another table).

    3. COJust to add... Binding them to the PharmacyDomainDataSource --- Seems to attempt to create a new pharmacy each time the datasource submitchanges() is called.. binding to the InventoryDomainDataSource does not link it to said pharmacy. ---- I've attempted to get around this by getting all the data from InventoryDDS and putting it into an IEnumerable List and then making Pharmacy.MedInv = that list. However this is too not working.

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.
