I would like to burn in a c# code behind property into the javascript alert(<%= someProperty%>); . For some reason it is not working. Is there a way you can burn the codebehind property into the javascript? thanks

Can you "view source" in the browser and see how the javascript renders? Try running in firefox + firebug and see what the reported error is?Joel Coehoorn– Joel Coehoorn2009-02-06 15:05:58 +00:00Commented Feb 6, 2009 at 15:05

Yes, there is a way and you are going in the right direction. Unfortunately, the way question is posed gives too little info about implementation and zero details about the problem.DK.– DK.2009-02-06 15:10:57 +00:00Commented Feb 6, 2009 at 15:10

Not sure if this works in your situation, but I think your best bet might be to attach the javascript to the event dynamically in your code behind on page load and just set the parameter value at that point.
For example:
btnSubmit.Attributes.Add("onclick","alert(" + someProperty + ");");

I think you are missing the ' try like this -->alert('<%= someProperty%>');

if you property has a ' in it it could break the javascript. Keep in mind that any javascript error may stop the rest from running.
Maybe it is a silly suggestion. Have you tried
alert("<%= someProperty%>");
?

To use the <%= => ASP.NET expressions, your Javascript cannot reside in an external .js file. It has to be part of the ASPX markup in order for the scriplet to be interpreted.
<head>
<script type="text/javascript">
alert(escape('<%=someProperty%>'));
</script>
</head>
Best regards...

You can use the ClientScript.RegisterExpandoAttribute method to register a C# code behind property into JavaScript property.
