Hi,

I have a page which makes use of Silverlight Isolated Storage. Now, when my page loads, it shows a hyperlink button that redirects the user to Silverlight download page (if he doesn't have it installed).

How can I prevent this link from coming at all? Like not just hiding it, how do I completely prevent it?

How do you expect silverlight isolated storage to work if the user doesn't have silverlight installed? Would you skip using any of your silverlight components/storage? Need more information about what you want the alternative action to be.

To find if there is Silverlight use this JS

JavaScript

function hasSilverlight() {
    try {
        try {
            // IE
            var AgControl = new ActiveXObject('AgControl.AgControl');

            return (true);
        }
        catch (e) {
            // Others
            if (navigator.plugins["Silverlight Plug-In"]) {
                return(true);
            }
        }
    }
    catch (e) {
        return (false);
    }
}

If the function returns true, then remove dom element...
