Creating Filter Pages for Filtering Tables

In C/AL code, you can use the FILTERPAGEBUILDER data type to create a filter page that enables users to set filters on multiple tables. Filter pages contains one or more filter controls, where each filter control can be used to set filters on a specific table. In the Microsoft Dynamics NAV client, filter pages are generated at runtime and run in a modal dialog box. The following figure illustrates a filter page that filters on the Item table.

To create a filter page, you use C/AL code and the functions that are available for the FILTERPAGEBUILDER data type. The following code example shows the C/AL code that creates the filter page in the figure.

FilterPageBuilder.AddRecord('Item Table', Item);
FilterPagebuilder.Addfield('Item Table', Item."No.", '>100');
FilterPageBuilder.PageCaption := 'Item Filter Page';
FilterPagebuilder.RunModal;
Item.SetView( filterPagebuilder.Getview('Item Table'));
