how write jquery for call controller name and action name binding dropdownlist?

Hi Venki,

You can use ajax call to MVC controller action like this

$('#ddlName').change(function () { 
    var parametervalue = $('#ddlName option:selected').val(); 
    $.ajax({ url: 'FillResources', type: 'POST',  //Give controller name/index name as URL
        data: JSON.stringify({ parameter: parametervalue }), //Parameter
        dataType: 'json', contentType: 'application/json', 
        success: function (result) { 
            //Enters if its success
        },
		error: function (){
		 //Enter if any error occurs
		}	
    });
});

Note: Above action method should have [HttpPost] attribute
Hope this helps you a bit.
