Tutorial: Nested queries using treeview

In this example demonstrates how to create a report using Nested Grid treeview. To build this application will be used two queries, one based on the Customers table (Grid Master) and another based on the Orders table (Grid Detail). (To access these tables just create the sample “Samples” project and use your database)

Creating the Detail Grid

1. Create a new application based on the Orders table.

2. Change the properties: Width Table and Table Width Unit for 100 and Percentage respectively.


3. In the application menu click on the SQL item

10. In the Name and Label property report “subgrid” and “Orders” respectively. To create the connection, click the Create button.

11. Select the detail grid and click the Next button.
