Question

I have a span element in my asp.net page without runat server attribute. I need to set this span’s visibility, but the decision to make it visible has to come from code behind. I don’t want to set runat=”server”

Answer 1

You could try something like this in your code behind, I am using jQuery but no need to really.

System.Web.HttpContext.Current.Response.Write("<SCRIPT LANGUAGE='JavaScript'>$('#MySpan').fadeOut('slow');</SCRIPT>");

Update:

You can read an variable from the server to see if you want to render the span or not while rendering the page. jQuery Code.. ShowMySpan is an public int variable on the server

<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        if (<%: ShowMySpan %> == 0) {
            $("#MySpan").css("visibility", "hidden");
        }          
    });
</script>
