Cancel remote paging and filtering
« on: September 20, 2016, 07:50:26 pm »
I have added an alert to the dataModel to cancel going to the next page and filtering if there is unsaved data in the grid.

Code: [Select]
beforeSend: function(jqXHR, settings){
                        var answer = confirm("Unsaved changes will be lost!");

                            return false;

Everything works correctly except the page number is still incremented even though the paging was canceled. Is there a way to stop the increment from happening?

I'm not clear in what kind of scenario you want to cancel remote paging and filtering together.

cancel paging is used in this example.

Code: [Select]
//check the changes in grid before navigating to another page or refresh data.
        grid.pager().on("beforeChange beforeRefresh", function (evt, ui) {
            if (grid.isDirty()) {
                var ans = window.confirm("There are unsaved changes. Are you sure?");
                if (!ans) {
                    return false;
