Generally when you want to set a default value for a parameter, you use the Value property of the parameter (this.ReportParameters["MyParam"].Value), but what to set when you want all values to be selected by default  i.e you have a multivalue parameter?

I am glad to announce that yesterday we released a public sample application built with RadControls for ASP.NET Ajax, ASP.NET MVC and Telerik OpenAccess. You can check the online demo, or download the source code. This application is a basic online forum which uses RadControls in ASP.NET and demonstrates integration with ASP.NET MVC. Here are a few screens from the forum: The "home" page (uses RadTreeView, RadGrid and RadMenu) The "new thread" page (shows RadEditor)

Currently it is in a Preview stage and you can find its roadmap here.  We have already demonstrated how to use the new client-side templates in RadTreeView and RadGrid.
