Hi,
AdvancedDataGrid Query

If you observe in the sample image when we expand clusterby by default it should contain Attributetype form without remove button for it. Next when we click on add button next to cluserby it should add mulitple nodes dynamically for example Attributetype and it should contain remove button for those added new nodes.And when we click on remove button it should remove that added nodes dynamically.

Simillarly for others also

1.ClusterBym

AttributeType

2.FilterComponent

ClusterAggregateFunction

3.AbstractQuestionSpecification

AttributeType
NodeColourRegex
NavigationStrategyComponentAlias

Below is my sample working code and image.

Thanks,
Alam.

Why do you want to use FORM container instead using datagrid rows?

Here we need to add multiple values and the client wants like this kind of UI. So that user can add mulitple values and can delete the values by using (-) delete button dynamically.I think you got my point.

 Boys:???, TotalStudent:???, PASSinper:???, FAILinper:???

Reg this as of now we are using only Boys in our sample code i guess rest not required.

http://livedocs.adobe.com/flex/3/html/help.html?content=advdatagrid_10.html

Do you want to replace chart by mx:Form or something different I couldn’t understand your requirements
