The way which you use in your previous question I don't like not because of the usage of "global" variable filter but because of complicated logic. Especially strange I find that you discard many parameters of jqGrid inside of your implementation of the serializeGridData event handle. I am sure that the code can be much simplified, but you don't posted more full JavaScript code which you use. Even which HTTP method you use to communicate with the server (do you use mtype:"POST" parameter or not).

Now about you main question. The variable filter should not be global. If should be visible. For example:

$(document).ready(function () {
    var filter = ''; //this is NOT global variable
    $('#btnsearchCode').click(function(){
        filter="...any value..."; // you can change the value of filter here
        //...
        $('#list1').trigger('reloadGrid');
    });

    $('#list1').jqGrid({
        // define jqGrid where you can use filter if needed
        // either directly of inside of body of any function
    });
});
