Modalpopupextender shows an existent webpage

[culebrin]

Hi,

I have a table maintenance page, and it has several details rows (and its respective maintenance page for that detail). Then I want to edit the detail using the modalpopupextender. I don't want to duplicate codes using the same that I have already. So I'm wondering, if its possible to show the content of a existent webpage inside the modalpopupextender.

If you need some code, let me know. Thank you very much.
