Web Forms :: How To Generate HTML Code By Commands From The Code Behind Page

Dec 30, 2010

how to generate HTML code from the code behind?

I would like to build a form that generate an html code inside a for loop.

I will let the user enter the photo name and No. of photos

Then I will generate an HTML code like this:

<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />

depending on the No. of the photos the code will be duplicated in the loop

Then I will display the result of the loop in label or in a textarea to let the user copy it any where

The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
