The "Mega Menu" component can be used in applications to provide another way of organizing the application's menu, showing several menu levels at once.

Mega menu

This component is available in the Aries design system. To use it, select it in the Design System Configuration wizard.

See more information in Mega Menu.

Enhanced PDF reports

PDF reports were strongly improved. They are now fully customizable and programmable allowing, for example:

  • Having different design for even and odd rows
    This is usually used to improve readability
  • Manage any attribute (position, font, borders, etc.) of any control in the report
    Design the aspect of titles, column headers, column values, etc. as you need.
  • Show multiple filters on the same row
    This reduces the space occupied by filters on the first page of a report.
  • Include the same aggregations shown in the grid
    See Include aggregation property.
  • Add code to be executed at given run time events
  • Have optional print blocks
    If, for example, you do not want the footer just remove it and it’s done.
  • Include any control type in the report
  • Show the report title anywhere you need it and even more than once
    Sometimes reports repeat the title in the Header and in the Footer of each page.

Customization is provided through enhanced Report Layout objects. Each PDF report may be assigned a different Report Layout.

K2BTools provides several standard Report Layout objects the developer can choose from. They are meant to increase productivity and as a documentation of how developers can build their own ones.

The following images show the structure of many Report Layouts distributed with K2BTools.

Attribute pills

It's sometimes good to provide "eye catchers" that let the application user interprete the information quicker and easier. For example:

  1. When confirming a sales order, the user may want to be alerted if the customer has a large outstanding debt.
    Customer debt pill

  2. When browsing the inventory, the user may want to easily identify products that are low in stock.
    Low inventory pick

  3. When booking a meeting, the user may want to be alerted if another participant is in a different time zone
    Timezone pill

Attribute pills can help in all the above situations. They can be shown next to or substitute the attribute value when a specified condition is met.

See more in Attribute Pills.

Row detail component

This feature can be used to add more information to standard grids allowing the user to analyze more information without leaving the panel.

The extra information is included in a web component that is displayed between grid rows. To see the details for a particular row, the user must click on the button on the right of the row.

Grid row detail activation

See more in Grid row detail feature.

Filters row

The developer can choose how filters associated with column titles can be shown. To do so, use the "Column Filters Position" property in K2BTools General Settings.

The default value (TitleMenu) is the one available in previous versions: Filters are shown as a menu associated with the grid's header row.

If the "FilterRow" option is chosen, the filters will be displayed as shown below.

Filters as an additional row

See more in Filters in column titles

Split Datepicker

The Split Datepicker control is designed to display date and time inputs with precision. It offers flexibility by allowing users to input dates as either discrete values or text values (with suggestions), and it can show either three fields (for date: year, month, and day) or five fields (for date and time: year, month, day, hour, and minute) depending on the fields data type.

This control ensures that the entered date and time are valid, taking into account factors like leap years and the length of months.
