Is there a way that I can pass a JavaScript function into a page (from a database) to be run? Background info I have developed a metadata driven asp.net mvc web site (basically I change data in the db, and the pages get generated on the fly). Unfortunately I have one page that has some routing requirements (i.e. if you choose option 1, then hide item x) I could solve this by having a custom page, but it would be nice if I could come up with a more robust solution. So what I am thinking is that I can attach an onchange event handler (based on a metadata value), and then somehow have some code that is executed based on that onchange event.

Everything works except the button image. All I need to do is make it so that the ButtonField.imageurl is loaded from my database. I dont want one picture for all I want a specific one.
I must be missing something very basic here.I have an asp:Image control where Visible="false." The idea is that I don't want the image to be displayed unless there is a value in a database column that contains a value for ImageURL, in which case my code behind switches visible to "true"But in IE8, these image controls are displaying as broken images, even when Visible="false". Why is that? And how do I fix this?.aspx:
in my page_load method I call a mthod that it create some dynamic controls. one of them is an Image control that it's ImageURL property set to an URL that is saved in data base. image shows that URL but when postback ocuurs, previous image controls doesn't their image. but other controls for example TextBoxes keep text values. what should I do for keep image url property for this dynamic Images controls?
