如何在按下按钮时从多个MVC3 Telerik控件中获取值并过滤屏幕上的其他控件？

Question

I have a couple of Telerik DropDownList controls and a RangeSlider that I want to set values on then have a button which applies this to another set of controls (filtering data down)

How do I get the values of the 3 different controls and apply it to say Charts?

Is the only way to do it with Client Side API and javascript? or can I pull it somehow with the model?

I tried doing a HTTP Post and the model returned to the Action was all null.

You will need to use JavaScript for sure. When the button is clicked you will need to use the rebind method of the Chart object (check here how to use it properly http://www.telerik.com/help/aspnet-mvc/telerik-ui-components-chart-client-api-and-events.html ) to send your values to the server and rebind the Chart

Also you will need to use the client side methods of the DropDowns and the Slider - to get the values.
