I'm using Devart for Mysql access.<br>
<br>
So what I have learned is, that, if you have a Master Detail relationship and<br>
you do a post with the Master table, the Detail table changes from edit to<br>
browse mode all by itself. !!!!<br>
<br>
Along the same lines if you have a Master Detail relationship and look to see<br>
if there is a Detail entry for a Master record and there isn't one, when you<br>
put the master into edit mode, it automatically creates one for you (or a<br>
virtual one) in the detail form so any conditional statement with the Detail<br>
table now returns true.<br>
<br>
So with Devarts components- things happen behind the scenes which can be hard<br>
to find.<br>

Thanks Wallace<br>
