Grab code behind property in Javascript?

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

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

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...

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 + ");");

Maybe it is a silly suggestion. Have you tried

alert("<%= someProperty%>");

?

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