Telerik UI for Windows 8 HTML

You can show and hide columns in RadGrid, using the control's API. This allows you to hide a column by default and show it upon some user action, or allow the end-user to show and hide columns as per their preference.

Hide columns by default

When you want to hide a RadGrid column in the initial view of the control, you just need to set its hidden property to true. The column will be rendered but with a display: none style applied to it. For example, with the following definition, the Age column will be initially invisible:

Show/hide columns Copy imageCopy
<div id="showHideGrid" data-win-control="Telerik.UI.RadGrid" data-win-options="{
            dataSource: {
                data: [
                    { Name: 'Peter', Age: 23, Points: 22.6 },
                    { Name: 'Mary', Age: 30, Points: 24 },
                    { Name: 'Mark', Age: 27, Points: 28.8 }
            columns: [
                { field: 'Name', title: 'Participant'},
                { field: 'Age', hidden: true},
                { field: 'Points', title: 'Score'}
<button id="btn">Click to show age column</button>

Show/hide columns programmatically

RadGrid exposes two methods to achieve the columns show/hide functionality - showColumn() and hideColumn(). Both accept a single argument, which must be the 0-based index of the column, or its bound field. In the second case, make sure that you pass the name of the field to which the column is bound and not the title of the column.

You can extend the above example to show the hidden column on button click with the following code:

Show/hide columns Copy imageCopy
document.getElementById("btn").addEventListener("click", function () {
    var grid = showHideGrid.winControl;
