Display null values at bottom in EJ2 JavaScript Grid control

13 Apr 20235 minutes to read

By default the null values are displayed at bottom of the Grid row while perform sorting in ascending order. As well as this values are displayed at top of the Grid row while perform sorting with descending order. But you can customize this default order to display the null values at always bottom row of the Grid by usingcolumn.sortComparer method.

In the below demo we have displayed the null values at bottom of the Grid row while sorting the OrderDate column in both ways.

var grid = new ej.grids.Grid({
    dataSource: Orderdata,
    allowSorting: true,
    actionBegin: actionBegin,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'OrderDate', headerText: 'Order Date', format: 'yMd', sortComparer: sortComparer, width: 120},
        { field: 'ShipCountry', headerText: 'Ship Country', width: 150 }
    height: 280

var action;
function actionBegin(args) { 
        if (args.requestType == "sorting") { 
            action = args.direction; 

function sortComparer(reference, comparer) { 
        var sortAsc = action === "Ascending" ? true : false; 
        if (sortAsc && reference === null) { 
            return 1; 
        else if (sortAsc && comparer === null) { 
            return -1; 
        else if (!sortAsc && reference === null) { 
            return -1; 
        else if (!sortAsc && comparer === null) { 
            return 1; 
        } else { 
            return reference - comparer;
