Great!

I was wondering how to display an image in iframe, the problem was that the image was dynamic and the name of the image keep on changing. Also, I needed to provide a save button that can launch the ‘Save As’ dialog (in IE only). The code that I had always show popup, but I didn’t want that, so I googled for it. I found a solution to put the image reference in an Iframe, so I did that.

Then I wanted to change the src of the iframe dynamically, how to do that, while reading your post around ‘….accomplish this by using two standard controls: PlaceHolder and HtmlGenericControl…..’ I got the idea to generate the iframe text dynamically and set that text as the literal control object’s text value.

And then…………. it worked!

Thanks for the post and the guidance.

Awesome!
I was having a problem with Atlas and an iFrame. Building it dynamically was the solution.
Great post!

Thanks for mentioning that Scott! I actually did read somewhere else that I could use src=”javascript:;” so that under https the warning would not appear and did set it to that for the iframe. Plus, I think setting it to that nonsense javascript will also save a request to the webserver.

One small piece of advice. If you are going to use this on a secure page (using https), you’ll have to set the src of the iframe to something on the site, otherwise you get a warning (at least in IE) telling you that the page contains secure and non-secure items.

I’ve seen people create a blank HTML page in the site and set the src to that. I set the src = “javascript:;”. That takes care of the warning.

I think, if I remember correctly, if you have inherited your user control from either a User Control or a Web Control, you can implement the marker interface INamingContainer and multiple instances of your controls will have a unique name. I’m not certain if you can do that with a user control, but I can’t think of any logical reason why you couldn’t. But when has development ever been logical? :)
