You're going to drown in code if I post my aspx ( 3221 lines so far ), but it's a customized ListDetails.aspx with in the formview a tabcontainer and on the 4th tab there's a grid which shows for example all related orderdetails of an order.

Anyway here's a piece of it. Search for TabPanel4 and you'll find the child grid. What I want is that the validation messages for this child grid are shown at the top where all the default validation messages are shown.

PS: I've tried to use the ClientID, the ID and the UniqueID, but nothing seems to work ...
PS2: Could it have something to do with Page_Load? I've tried in Page_Init, but I can't get it to work there either.
