    Posted: 13 July 2009 at 4:35am
For testing this, create a project with:

- a report control, with .MultiSelect = True
- enable grouping, and group on a column (whatever column)
- select some (mulitple) rows
- collapse the group where the selected rows belongs
- expand the group again

... the selection(s) are lost.


This happens also in last version 13.1.

I don't know about pre-historical versions but I just build 12.1 and
you can try it for this problem - same as in 13.0 and 13.1 - child selection lost -

Who is talking about pre-historical versions? I tested this with version 13.0, and yesterday I tested it with latest version 13.1 (downloaded from the forum).
In your test project, this is the same, and happens the same way I described.

Hi Marco,
 
What Mark is trying to tell you that the bug has been there all the time and it seems he doesn't see that this is wrong behaviour...

Hi, Aaron

thanks for the explanation (didn't understand that way...).
Anyhow, it is a bug in my opinion, and it needs fixing: in case I have multiple selection active, I can do some selections in my report, and then just collapsing a group will lose the entire work I did....


The fact that this was already present in older versions doesn't mean it is a bug.

Hi Marco,

Mark will reply something like: This is expected behaviour or this is implemented with Microsoft guidelines or some other cryptic reply.... So I think you have to do this yourself. 
 
So maybe you can create own SelectedRow collection (I didn't test if ReportControl's SelectedRow collection is really destroyed, maybe it still exists and is still useable) and create function to select the rows. Call this function after a row is expanded (RowExpanded event) and you will keep the rows selected all the time.
 
Good luck

Well, I'm actually already using a "special" version of the multiple selection, done using this approach:

http://forum.codejock.com/forum_posts.asp?TID=12832&KW=sticky

So, I do have a "private" collection keeping the selected rows, and this is updated each time the selection changes.
Anyhow, I saw that collapsing a group seems to "destroy" the selected rows, as the effect is that I loose all the selected rows belonging to the collapsed group...

So, I decided to test it with the "builtin" MultipleSelection property, and I noticed the same behaviour.
Thanks for your reply, again.

Hi Marco,
 
I don't know if you have an active subscription? You could write to support and ask if this could be changed, you have my vote on this.
 
It's strange that SelectedRows collection is destroyed just because one row is expanded. If I look at the SkipGroupRowFocus property and user is still able to select the row even when SkipGroupRowFocus = True, this could be easily used for this too, when True I can't select a grouprow and SelectedRows collection don't have to be destroyed as well  (Mark???)
 
Thanks

No - it clean - you need to keep your own collection and use your own logic

I did created a support request on this issue.
Acutally, it seems to me that the SelectedRows collection is not destroyed, but actually the rows belonging to the group that is collapsed are "removed" from the collection itself.
In fact, other selected rows (not "childs" of the collapsed group) are keeped (selected); only the "childs" are non-selected.

Thanks, Aaron.

Hi Marco,
 
So you are saying that only childs of collapsed rows will be removed from collection? That's strange... I don't see difference with expanded rows, you? Sometimes RC implementations aren't logical but I suppose it's me who isn't thinking logical
 
Well, good luck with your request !!!

Hi, Aaron,

well, I'll have to double-check this better to give you a more detailed answer...
Thanks

This is that I said - "it clean" (selected Child records) - of course collapse-expand action not changed other records

Well.. if collapsing-expanding a group does clean the selected child records (this is what you are saying, right?), how can I keep track of them in the application?
I should keep track that the row was selected, and since it belongs to the group that is collapsed (how?), it should remain in my personal collection of selected rows even if it is not...

I hope you'll agree that this is really difficult, and too much work for a feature that should be already present in the report itself.

It looks simple - On Collapse event you add indexes of childs in your collection - On Expand - you select from your collection and clean it

Hi Mark,
 
  1. Question: Does collapse row destroy SelectedRows collection? if yes: Why?
  2. Question: Does expand row destroy SelectedRows collection? if yes: Why?

Thanks

Demo with persist child selection here - https://forum.codejock.com/uploads/DemoVersion/ReportSampleStaticProto.rar
 
You can also use standard VB Report Sample to play with fresh OCX supported persist child selection

Well, this version seems working the way I expect. 
I'll make some test more, and I'll post feedbacks about this.
Thanks.

P.S. do you prefer continue with this issue in here on in the "IssueTrack"?

You can close issue but I am expecting good (non-surface) testing feedback - if you like to keep it private - use issue
