Hello, 

You can reach this behavior by passing a parameter to your action, after that filter the data on the server.

You can pass parameter this way : 

 

.Read(r=>r.Action("People", "Home").Data("functionName")))

 

Where 'functionName' is the name of the function which will return your parameter. In your case this function is simple you just return true or false depends on that, is the switch is on or of:

 

    function functionName() {
        return {
            paramName: value
        }
    }

 

You have to setup the switch to force the Grid to make a request. Here is the whole snippet:

 

var isChecked = true;
    $(document).ready(function () {
        $('#switch').kendoSwitch({
            change: function (e) {
                isChecked = e.checked; //true/false depends on that is the switch is turned on
                $("#grid").data("kendoGrid").dataSource.read(); // make request
            }
        });
    })
    
    function isActive() {
        return {
            isActive: isChecked
        }
    }

 

You action declaration should be something like this:

 public ActionResult People([DataSourceRequest] DataSourceRequest request, bool isActive)
        {

            var people = Enumerable.Range(1, 50).Select(x => new PersonViewModel
            {
                FirstName = "MyName" + " " + x,
                IsActive = x % 2 == 0
            }).Where(x=>x.IsActive == isActive);
            return this.Json(people.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
        }

You can use the parameter to filter the data in the action, or you can make different queries conditionally, based on the value you get in the action.
