Usually people like to write the AdvancedDataGrid component in mxml. But there are some scenarios where there is a need to create the grid dynamically.
Here is a simple sample in which an AdvancedDataGrid is created dynamically with column groups.

Hello Advanced DataGrid users,
We have added a poll about AdvancedDataGrid’s performance. Please take part in the poll and help us identify the areas which needs improvement.
The poll is hosted at flexpearls
In this sample, I’m using an Advanced DataGrid as an item renderer within another Advanced DataGrid. This type of configuration is very useful to give a master-detail view. This configuration can be customized more depending on any specific requirements.
Application Source, Renderer source
Thanks to Sreeni for coming up with this.
When you set Object/Collection as a source for an AdvancedDataGrid to display the source in a Hierarchical manner, the AdvancedDataGrid.dataProvider will return an instance of IHierarchicalCollectionView because internally the source is used to construct a HierarchicalCollectionView which is returned via the dataProvider property.
What if, you want the original source from this IHierarchicalCollectionView. Well, there are some API’s for achieving this –
// First, get the HierarchicalData used to create the HierarchicalCollection
var hd:IHierarchicalData = IHierarchicalCollectionView(adg.dataProvider).source;
//From the HierarchicalData, get the source collection/object
var source:Object = hd.getRoot();
Here is a sample.
There is a post in Flex component Yahoo group on how to show a 3-state checkbox in an AdvancedDataGrid.
It has been implemented for the Flex Tree Control in the Flex cookbook.
I thought lets write a similar example for AdvancedDataGrid. I made some changes in the original sample and here it is; working for the AdvancedDataGrid control.
This example shows how AdvancedDataGrid can be configured to show summary with the Group node.
Here, I’m using GroupingCollection to calculate the Summary with summaryPlacement being “group”. Then using groupLabelFunction in AdvancedDataGrid and returning the Group Node’s value plus the Summary value.
