In any GUI tool, one of the most popular components is the one that shows
data in a table format like JTable in Java or Datawindow in PowerBuilder. The
Adobe Flex 2 version of such a component is called DataGrid. In any UI
framework, the robustness of such a component depends on formatting and
validating utilities as well as a whole suite of data input controls:
CheckBoxes, ComboBoxes, RadioButtons, all sorts of Inputs, Masks, and so on.
Using theatrical terminology, the role of the king is played by his
entourage. Practically speaking, touching up the DataGrid is touching up a
large portion of the Flex framework.
We'll start by upgrading the standard DataGrid to a "destination-aware"
control capable of populating itself. Next, we'll look at the task of
formatting Data... (more)

enables you to create, combine and/or extend existing components with a
simplicity and elegance hardly ever offered by other GUI development

Browser-based applications are widely used and we like the fact that we can
access them from anywhere. But from the users' perspective, the productivity
level of Web applications still doesn't approximate the productivity of
desktop programs. The good news is the gap is closing: the accumulated
potential of multiple technologies has boosted a whole new breed of
HTML-based apps that are a... (more)
In Part 1 (CFDJ, Vol. 8, issue 10) we introduced the destination-aware grid,
formatters, and renderers. In this article we are continuing our discussion
about datagrid renderers and...
RadioButtonGroupBox as Drop-In Renderer
We can apply similar techniques to RadioButton controls. The following code
snippet suggests how the group of RadioButton controls can be used as a
drop-in item rende... (more)
