Parent-Child Form (1 Viewer)

[Martyh]

Hi!
How can you tell (programmatically) if there is value in a Child ?
eg Me!sfrmAttachmentDetails.Form!ParticipantID

I currently have a form and a sub form in a typical 1 to many relationship.

I would like to know how I could determine if there is data entered into the many side of the relationship.
This is for a deletion control on the main form:
1) On delete of the many, if there is none, do nothing.

2) If there is, then delete.

I have no. 2 figured out but I just can't get my head around No. 1

Please HELP!!

Have already tried:
isNull(Me!sfrmAttachmentDetails.Form!ParticipantID)
isEmpty(Me!sfrmAttachmentDetails.Form!ParticipantID) &
isError(Me!sfrmAttachmentDetails.Form!ParticipantID)
None of these appear to work!

I don't worry about first checking to see if any records exist before running a delete query. I just try to delete any related records by running the query.

I have not had an issue running a delete query when there are no records.

Are you getting an error?

If you really want to check then try:

If Me.sfrmAttachmentDetails.Form.RecordCount > 0 then 
' run the delete code
End If

Hitech Is absolutley right
do not worry if there is data or not you are going to delete it after all

Hitech coach and thunder!

Thanks for your quick reply!

I guess I need a kick in the pants! Of course your solution is right! I was getting an error message that there was no record ... but duh!!

Thanks
