Hello,

So, you mean that you want to add a link/hyperlink button in there to accept the new row?
Normally, you can do it with using shift + enter. But, if you want to add a link/hyperlink button, you need to get the element of the object and insert link/hyperlink button in there.
However, wouldn't link/hyperlink button cause FullPostback to the page? If it does fullpostback, then I think would not be possible to use.

Hello Zak,

You can hide the add new row but I am not sure if you can use link button since it would cause a fullpostback. At least, you know how to add the new row programmatically.
The rest is up to you which approach that you would like.
