The designer context blocks are primarily responsible for putting data into the global context so that they can be referenced by the application blocks or Business Central.

The following sections outline each available context and provide a brief example of how the block can be used.

Using the Selected Line

Using the Selected Line is intended for applications that are displaying a data grid (or card panel). This block takes the currently selected line (or panel) and adds each column from the underlying dataset to the context. Variable names match the column name.

Using the Selected Line

Using the Selected Line Example

The Application Designer example below uses Using the Selected Line. The application loads an item list of data and once loaded displays a message indicating the selected item number.

Form Opens

Using the Document Header

Using the Document Header is intended for applications that are displaying a data grid (or card panel). This block takes the current document data header information and add each column from the dataset to the global context. Variable names match the column name.

Document Header

Using the Document Header Example

The Application Designer example below uses Using the Document Header. The application loads a warehouse receipt document and once loaded displays a message indicating the receipt document number.

Using the PDA Configuration

Using the PDA Configuration pushes the Business Central PDA Configuration options into the global context so they can be referenced as needed. In addition, information concerning the current location is also made available (e.g., bins mandatory, require picks, etc.).

The Application Designer example below uses Using the PDA Configuration:

Using the Last Scanned Barcode

Using the Last Scanned Barcode pushes the last barcode data into the global context. The context that is created depends on the type of barcode and are listed below. Typically, this block is used when responding to a barcode scan event (See Designer Events for more information).
