Hi, I wasn't sure where to put this suggestion/request but would it be possible for you to add a static "cast()" method to your client side javascript classes?

I know Visual Studio SP1 has had some work done to improve the javascript intellisense but currently there is a common scenario where intellisense fails and could so easily be fixed.

The scenario is where you have a client side event handler, for example:

...
var win = new Telerik.Web.UI.RadWindow(parent);
win.initialize();
...
win.add_close(function(sender, e)
    {
        // No intellisense on "sender" or "e".
    }
);

What would be useful is if the handler could be written like this:

win.add_close(function(sender, e)
    {
        sender = Telerik.Web.UI.RadWindow.cast(sender);
        e = Telerik.Web.UI.RadWindowEventArgs.cast(e);

        // Intellisense is now fully enabled on "sender" and "e"
        sender.dispose();
    }
);

The actual code you would need to add to your classes would be like this:

Telerik.Web.UI.RadWindow.cast = function(obj)
{///<returns type="Telerik.Web.UI.RadWindow"/>
    return obj;
}

I hope that makes sense and I'm sure it would be very useful to any developers dealing with an increasingly complex client side API.

Many thanks

Hi Kevin,

Thank you very much for your suggestion, it seems really useful. I logged it in our database for future consideration and most probably it will be implemented but I cannot tell you exactly when.

We appreciate very much your cooperation and we hope that it will continue in the future, too.

All the best,

It would be really great news if you could!

It is unfortunate that

1) Microsoft do not implement a "cast" method, although I have suggested it. Perhaps you could suggest it also?

2) The current JS intellisense feature for VS2008 cannot handle the huge size of the entire Telerik client side library. Possibly SP1 may solve this but for now, I find one can only reference one part of the Telerik library at a time. This is the kindof template I use for Telerik client API references, where only one "region" can be included at a time. This took a long time to discover and you may want to include this information in your docs also for anyone wanting client side Intellisense for Telerik classes:

Finally, here is an add-in script I currently use in order to retrospectively fit the "cast" method to Telerik Q1 2008 client classes. It maybe useful to someone else until such time Telerik implement the method (hopefully you will), then can be removed.

Thanks

Kevin
