I created the DP and set it as the data source of AdvancedDataGrid.
DataProvider
------------------
[Bindable]
private var dpFlat:ArrayCollection = new ArrayCollection([
{TaskName:"Project 1", PlannedStartDate:"12-01-2009",
PlannedEndDate:"02-03-2009", TaskId:1, ParentTaskId:1},
{TaskName:"Task 1", PlannedStartDate:"12-01-2009",
PlannedEndDate:"22-01-2009", TaskId:2, ParentTaskId:2},
{TaskName:"Task 1.1", PlannedStartDate:"12-01-2009",
PlannedEndDate:"18-01-2009", TaskId:3, ParentTaskId:3},
{TaskName:"Task 1.2", PlannedStartDate:"19-01-2009",
PlannedEndDate:"20-01-2009", TaskId:4, ParentTaskId:4},
{TaskName:"Task 1.3", PlannedStartDate:"21-01-2009",
PlannedEndDate:"22-01-2009", TaskId:5, ParentTaskId:5},
{TaskName:"Task 2", PlannedStartDate:"23-01-2009",
PlannedEndDate:"02-02-2009", TaskId:6, ParentTaskId:6},
{TaskName:"Task 2.1", PlannedStartDate:"23-01-2009",
PlannedEndDate:"28-01-2009", TaskId:7, ParentTaskId:7},
{TaskName:"Task 2.2", PlannedStartDate:"28-01-2009",
PlannedEndDate:"31-01-2009", TaskId:8, ParentTaskId:8},
{TaskName:"Task 2.3", PlannedStartDate:"01-02-2009",
PlannedEndDate:"02-02-2009", TaskId:9, ParentTaskId:9},
{TaskName:"Task 3", PlannedStartDate:"03-02-2009",
PlannedEndDate:"02-03-2009", TaskId:10, ParentTaskId:10},
{TaskName:"Task 3.1", PlannedStartDate:"03-02-2009",
PlannedEndDate:"23-02-2009", TaskId:11, ParentTaskId:11},
{TaskName:"Task 3.2", PlannedStartDate:"23-02-2009",
PlannedEndDate:"26-02-2009", TaskId:12, ParentTaskId:12},
{TaskName:"Task 3.3", PlannedStartDate:"27-02-2009",
PlannedEndDate:"02-03-2009", TaskId:13, ParentTaskId:13}]);
Grid
------
<mx:AdvancedDataGrid id="myADG" width="100%" height="100%"
initialize="gc.refresh();">
<mx:dataProvider>
<mx:GroupingCollection id="gc" source="{dpFlat}">
<mx:grouping>
<mx:Grouping>
<mx:GroupingField name="TaskName"/>
</mx:Grouping>
</mx:grouping>
</mx:GroupingCollection>
</mx:dataProvider>
<mx:columns>
<mx:AdvancedDataGridColumn dataField="TaskName" headerText="Task
Name"/>
<mx:AdvancedDataGridColumn dataField="PlannedStartDate"
headerText="StartDate"/>
<mx:AdvancedDataGridColumn dataField="PlannedEndDate"
headerText="EndDate"/>
<mx:AdvancedDataGridColumn dataField="TaskId"
headerText="TaskId"/>
<mx:AdvancedDataGridColumn dataField="ParentTaskId"
headerText="ParentTaskId"/>
</mx:columns>
</mx:AdvancedDataGrid>
But while displaying the output is,
[-]Project 1
Project 1 12-01-2009 02-03-2009 1 0
[-]Task 1
Task 1 12-01-2009 22-01-2009 2 1
[-]Task 1.1
Task 1.1 12-01-2009 18-01-2009 3 2
[-]Task 1.2
Task 1.2 19-01-2009 20-01-2009 4 2
[-]Task 1.3
Task 1.3 21-01-2009 22-01-2009 5 2
[-]Task 2
Task 2 23-01-2009 02-02-2009 6 1
[-]Task 2.1
Task 2.1 23-01-2009 28-01-2009 7 6
[-]Task 2.2
Task 2.2 28-01-2009 31-01-2009 8 6
[-]Task 2.3
Task 2.3 01-02-2009 02-02-2009 9 6
[-]Task 3
Task 3 03-02-2009 02-03-2009 10 1
[-]Task 3.1
Task 3.1 03-02-2009 23-02-2009 11 10
[-]Task 3.3
task 3.2 23-02-2009 26-02-2009 12 10
[-]Task 3.31
Task 3.3 27-02-2009 02-03-2009 13 10
HOW TO CHANGE THIS IN TO THE BELOW FORMAT
[-]Project 1 12-01-2009 02-03-2009 1 0
[-]Task 1 12-01-2009 22-01-2009 2 1

[-]Task 3 03-02-2009 02-03-2009 10 1
[-]Task 3.1 03-02-2009 23-02-2009 11 10
[-]Task 3.3 23-02-2009 26-02-2009 12 10
[-]Task 3.3 27-02-2009 02-03-2009 13 10
