Populate() automatically expands groups

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Greetings,

We're trying to use the report control to display data that is refreshed on an interval.  Whenever we update the data, we iterate the rows and call the Set*() methods on them, then Populate().

Here's the problem:

If item A is under a group called "Group 1" and you collapse Group 1, the next call to Populate() expands Group 1.  We do not wish for this to happen.  Is this a bug?  Is there a way to stop the control from expanding collapsed groups on a call to Populate?

Thanks in advance!

	Before your call to update data from data source you can remember all group states (expanded or collapsed) and after populate restore this states set again - looks very easy. Default behaviour is proper as after you change data some of groups can changes - e.g. previous visible child row will be invisible under your logic as now will have another group row which can be collapsed.
