Getting the page number that an object is on, inside a $sendall
Hi $All,
I’ve done this before, I’m sure of it! But I’m having brain fade.
We validate our fields on a window by doing a $sendall, and then displaying the result to the user.
It looks something like this:Calculate isErr as ”
Calculate isWarn as ”
Do $cwind.$objs.$sendall($ref.$validate)
If len(isErr)
OK message Validate {[isErr]}
Quit event handler (Discard event)
Else If len(isWarn)
Yes/No message Validate {[isWarn]Continue anyway?}
If flag false
Quit event handler (Discard event)
End If
End IfIn this particular case, I have a paged pane, and I only want to validate fields on eg page 2. I know that I can specify a condition in the $sendall, and I know that there’s a $panenumber() method that will tell me which pane an object is on.
I think it should be something like this:Calculate pnCurrentPage as 1
Do $cinst.$objs.PagedPane.$objs.$sendall($ref.$validate,$cinst.$objs.PagedPane.$panenumber($ref)=pnCurrentPage)But this doesn’t do anything. Has anyone done anything like this before?
All help gratefully received.
Regards,
Paul.

Hi Everyone,
With help from the list, and some personal replies, here’s what I found:
At first, I couldn’t get the $sendall to work, so I coded this which did work:Do vlObjects.$define(vrObject) ;Create a list of objects that we want to work with
Do $cinst.$objs.PagedPane.$objs.$sendall(vlObjects.$add($sendallref)) ;Add all objects from this page pane into a list
Begin reversible block
Set current list vlObjects
End reversible block
For each line in list from 1 to #LN step 1
If $cinst.$objs.PagedPane.$panenumber(vlObjects.vrObject)=pnCurrentPage ;This is on the page that we want to validate
Do vlObjects.vrObject.$validate() ;Call this specific validate method
End If
End ForThen I received a couple of replies, which led me to this:
Do $cinst.$objs.PagedPane.$objs.$sendall($ref.$validate(),$cinst.$objs.PagedPane.$panenumber($sendallref)=pnCurrentPage)
Note using $ref in the first part, and $sendallref in the second part.
