The DataGrid is a commonly used component when creating applications in Flex. The component can represent columnar data with ease when connected to a dataProvider. There is a method of editing the data in the DataGrid without using an itemEditor. Of course, there is nothing wrong with using an itemEditor, but this alternative method of using a PopUp window deserves some consideration when implementing applications. This article by Keith Lee describes how to create a DataGrid, display a popup for each row of the DataGrid and add, edit or remove data from the DataGrid using the PopUp.Read Editing DataGrids with Popup Windows in Flex in full

In this article by Ian Wild, we will be looking at taking our current resources and converting them over to Moodle. I'm going to concentrate on the kinds of resources we math teachers usually have. They usually come in two flavors. The first are the "static" resources: PowerPoint presentations, documents provided by publishers (such as resources provided on a CD-ROM at the back of a textbook or downloadable from the publisher's website). In this article, we'll focus on these static resources. Again, those are the resources math teachers and lecturers usually like to convert to Moodle. The other type of resources are "interactive" resources.
In this article we will learn the following:
- How to create math-related PowerPoint presentations and, using the content sharing website SlideShare, include them in our Moodle courses along with a suitable narration
- How to extract math-related videos from YouTube and include them in our courses
- What a screencast is and how it can be used to explain mathematical concepts
