Store the row itself in a member variable on the form of type UltraGridRow.

I think the AfterRowExpanded event is what I would use.

I don't see how InitializeRow would work for what you want here.

Hello Mike,

Even I have the same Problem to work on. I got your point.

But how to store that row which has been expanded ??

Can I write this in the RowInitialize Event.

Hi Clay,

There's nothing built-in to the grid to only keep one row expanded at a time. But you could implement this very easily as Brian suggested.

You cannot collapse Band1, though. The Expanded or collapsed state it a function of the parent row, not of the child band.

The grid fires events when a row is expanded or collapsed: BeforeRowExpanded/AfterRowExpanded, BeforeRowCollapsed/AfterRowCollapsed.

So you could use AfterRowExpanded to keep trap of when a row is expanded and store that row. The next time a row is expanded, you can call the Collapse method on the previously-expanded row.

Hello

I'm sorry but I don't understand your reply.  There is no command to colapse just 1 row and the collapseall doesn't give me what I'm looking for.  Let me restate the problem.

I have band0 that  has n rows.  Each row in band0 has a child band (band1) containing n rows.  When I select a row in band0, I want to close the open band1 (if it exists), and then expand the child band (band1) of the band0 row that I selected.

Thank you
