Brian,

>When I call a Function on the parent oClient to populate the dataset it isn't fireing the HookParentRetrieved sub on the Child. Is there something else that I need to do to setup the parent-child relationship in the BizObjects?

There isn't...I see you used the overload of RegisterChildBizObj that accepts a table name. The hook method only fires in the child if the parent business object retrieved data into the table you specified.

You might want to check the spelling of the table name to make sure it's correct. That said, if the child business object only works with a single data table, you don't need to specify the table name and can use the other overload of RegisterChildBizObj that only accepts a single business object reference parameter.

Regards,
