Hyperlink's, ImageURL's, and OnError's

I created an ASP:Hyperlink and set the ImageURL attribute so the link will be the image.
If the image is missing, I would like it to display a 'missing image' pic that I have.  I know you can use the OnError attribute of the <img> tag to run some javascript to change it.
Unfortunately I can't find a way to access the Hyperlink's Image that is inside it, so I can add an Attribute so the resulting <img> tag will have an OnError attribute inside of it.

Any help?

If my Hyperlink is called 'foo'....would I do...  ((Image) foo.Controls[0]).Attributes.Add("OnError", "myjavascripthandler();");

How do I get to the Image inside the hyperlink?

um, ive never really done that, but i would try running the page, viewing the source, and seeing if it gives the image an id, then use find by id. if it doesnt work in the code behind, you can do it with javascript get element by id. if that doesnt work, and youre positive the image is a sub control of the hyperlink control, you could do a

 

for each c as control in foo.controls



if typeof(c) is getType(image)

 add attribute

etcetc

Yeah i fixed it on my own.

Instead of using the Hyperlink's ImageURL attribute, I just made an Image inside of it so I had direct access to it programmatically.  Then I added the OnError attribute, hooked up the javascript and I was good to go :)

Who's show is SN? Steve's or Leo's?
I don't want to start anything (honestly)! Just want to ask a simple question. Does the Security Now podcast belong to Steve Gibson or Leo Laporte? Maybe I'm in a world all to myself, but when I listen to the excellent SN podcasts, I want to hear STEVE, not Leo. But especially in the past few shows, it seems Leo will repeatedly interrupt Steve in the middle of a sentence that I want to hear the rest of. I consider this very rude of Leo. Steve is making a point that I (we) want to hear, then looses his train of thought after Leo barges in and asks something. It...

DataSet's DataTable's and TableAdapter's Oh My!
Here is my situation.  I am using VB as my programming language.I am creating a part of a website that will be the admin section.  I want the admin to be able to add/edit data in a set of tables that normal users can't.  There are 20 lookup tables that I use in the website that I want the admin to be able to manage (i.e. add, edit, delete, insert).  I don't want to create 20 separate web pages (one for each table).  I have one page that has links to all the tables.  Each link has a "table" querystring variable associated with it.  When the...

I like to give some of my users controll over their print jobs. In Netware 3.x to 4.x it was pconsole. In Netware 5.x it was NWPMW32.

Mozilla get's no style tag's from .net server.
I made a webform in web matrix, and it looks fine in IE. If I open the same link whit Mozilla, it looks like a disaster. When I look at the HTML source, there are no style tags as in IE. But when I save the HTML source from IE (the one whit style tags) and open it in Mozilla, it looks perfect. So the onley reason the webform looks wrong in Mozilla, is because the .net server detects Mozilla and not IE and sends a style less HTML source. Wy? Mozilla does support style tags. Is there a solution for this bug? Or is this a uh.. feature? ..Mivz Update, I have got some more info. It is ...
