The Data table control has an Items property that is set at design time, but it cannot be accessed in a formula such as Datatable1.Items. This would be useful when we want to get a count of rows and the Items property contains Filter functions. It would be much cleaner to use CountRows(Datatable1.Items) rather than having to duplicate the entire Filter expression in the CountRows formula.
The Gallery control has an AllItems property. I would like to see a similar property added to the Data table control.
