Expand exclusive in Hierarial Grid

[Asaf Segal]

Hi
I need to expand exclusivly an hierarial grid:
When I expand a row I want all the others to be closed. ( In my configuration the clicked row is selected )
I tryed to collapse all rows in Expanding event - this made an expand in a wrong row.
I tried to collapse the previous expanded row
In Expanded event, this made the selected row point to the place that the Expanded row was before the collapse
( there is a call to moveTo somewhere in the mouse up handling )

Is there a way to achive the behaviour I need ?

I do not know of a good way to do this.

Attached is a try at it, but it uses a timer to position the current cell in one case where it was being reset the way you described.

Thanks for the sample.
Is there a way to avoid the flickering when selectibg the row with the timer event ?

I think most of the flickering is being caused by the currentcell being positioned and then moved. There is a DrawCurrentCellFrame event that you can use to avoid drawing the current cell frame. So, if you set a flag when you do not want it drawn, and then cancel this event based on this flag, then you might be able to avoid some of the flicker. But I am not sure you will be able to remove all flickering without a lot of tickering to handle things perfectly. Attached is a rough try at doing this.
