In this post, we will show you how to programmatically Show and Hide GridView columns.

The following example code creates a jqxGrid and populates it with local data.

// prepare the data
var data = new Array();

var firstNames =
[
    "Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene"
];
var lastNames =
[
    "Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier"
];
var productNames =
[
    "Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Cramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist"
];
var priceValues =
[
    "2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0"
];
for (var i = 0; i < 2000; i++) {
    var row = {};
    var productindex = Math.floor(Math.random() * productNames.length);
    var price = parseFloat(priceValues[productindex]);
    var quantity = 1 + Math.round(Math.random() * 10);
    row["firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
    row["lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
    row["productname"] = productNames[productindex];
    row["price"] = price;
    row["quantity"] = quantity;
    row["total"] = price * quantity;
    data[i] = row;
}

var source =
{
    localdata: data,
    datatype: "array"
};

var dataAdapter = new $.jqx.dataAdapter(source);

$("#jqxgrid").jqxGrid(
{
    source: dataAdapter,
    columns: [
        { text: 'First Name', dataField: 'firstname', width: 100 },
        { text: 'Last Name', dataField: 'lastname', width: 100 },
        { text: 'Product', dataField: 'productname', width: 180 },
        { text: 'Quantity', dataField: 'quantity', width: 80, cellsalign: 'right' },
        { text: 'Unit Price', dataField: 'price', width: 90, cellsalign: 'right', cellsformat: 'c2' },
        { text: 'Total', dataField: 'total', cellsalign: 'right', minwidth: 100, cellsformat: 'c2' }
    ]
});

The resulting GridView is displayed below:



To hide the “First Name” column, you can use the ‘hidecolumn’ method. The method accepts 1 parameter – the column’s datafield.

Let’s call the ‘hidecolumn’ method:

$("#jqxgrid").jqxGrid('hidecolumn', 'firstname');

Here’s the result after hiding the ‘First Name’ column:



To show a column, you can use the ‘showcolumn’ method:

$("#jqxgrid").jqxGrid('showcolumn', 'firstname');
