I have an iframe in Masterpage updatepanel . It has an .html page as its source. So, there is a textarea where the html page is displayed . When i modify the html page in the textarea and click on a button , it should update the html content back to html page. [Basically i want the updated dom of the iframe to be assigned back to the innertext of the html body of the html page . i am currently using htmlagility pack to achieve read and save of the .html page. The only thing not working is the updating of .html file dynamically .
Is it possible to do so ?
