Hi,

I don't see anything wrong with this code.. but can you ensure that the element added last time preserved during the second time you click the button. cause on postback may be your table getting reintialized and your control you have added is removed and the second control added as the first one.

Verify when you are clicking the button that the tblOtherQualification has the last control added in it. if it isn't then try to preserve it first.

Hope this helps you.

Thanks
