Question

I want to trigger the change event of dropdown in $(document).ready using jquery.

I have a cascading dropdown for country and state in user details page. how can i set the value (which is taken from DB based on the user id) for country and state in MVC with C#.

I don't know that much JQuery but I've heard it allows to fire native events with this syntax.

$(document).ready(function(){

    $('#countrylist').change(function(e){
       // Your event handler
    });

    // And now fire change event when the DOM is ready
    $('#countrylist').trigger('change');
});

You must declare the change event handler before calling trigger() or change() otherwise it won't be fired. Thanks for the mention @LenielMacaferi.
