[TaylorJ]

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?\[code\]<Grid x:Name="LayoutRoot"> <Button Content="Save Changes" Height="52" Width="103" Name="SaveChangesButton" VerticalAlignment="Top" Click="SaveChanges"
