ExpandAll/CollapseAll functionalities; Load subtasks if an element is expanded

[Maksym]

Hello, 

2 questions:

1. I am currently trying to implement a functionality that can expand/collapse all tasks in grantt view. Are there some build-in tools that can be used to implement these functionalities?

2. I also want to load the subtasks of a root task if it is expanded. So I am looking for a function that notifies if a task is expanded.

Thanks.

Hello,

You could load all summary tasks either expanded or collapsed from the server via the ExpandedField from the TasksDataBindings. In case you want to collapse/expand them on the client you should use the client-side API of control as shown in the attached sample page.

Regarding your second question, RadGantt does not provide "lazy loading" of its child tasks.
