Thank the stars that you posted this - I was buggering around with this for ages and finally have a kind of work around.

 I dont know why it does what it does - however I took note of what you said about doing it in code rather than on the

aspx page. So I re-did mine to get the datasource etc from the aspx page and it works as it should!

You dont have to overide any of the event handlers either - what a daft error that is!!!!!
