Question

i wonder if there is any way to call an asp method that returns a string or something when you are in <script></script> tags.

Like this (it does not work):

    <script language="javascript" type="text/javascript">
    function isValid() {
        var required = "<%= callAspMethodThatReturnsSomething() %>";
    }
    </script>

any help with this? thx!

The issue is that you are calling a method on the master page from the content page directly.

You can’t do that – you need a reference to the strongly typed master page.

Try this (asp.net 4.0):

<%:((MasterPageClassName)Page.Master).callAspMethodThatReturnsSomething()%>

Or this (pre 4.0):

<%=((MasterPageClassName)Page.Master).callAspMethodThatReturnsSomething()%>
