Operations folder that is a direct child node of a data collection (for example,
OrdersView1) contains operations that affect the current row in the collection or operations that refresh the data collection.
Operations that affect the current row include First and Last, which sets the current row to be the first row or last row, respectively, in the row set. Operations that refresh the data collection include Execute, which refreshes the data collection by executing or reexecuting the view object's query.
When you drop an operation on the page, the Create context menu displays for you to select the type of UI control for the operation. In the example you will add four buttons between the Panel Header component and the Panel Group Layout component. You will use the operations First, Previous, Next, and Last. At runtime these buttons enable users to browse the records in the orders form.
