How to show or hide columns in Gantt at runtime

Platform: jQuery |
Control: ejGantt |
Published Date: June 30, 2017 |

In Gantt, It is possible to show or hide columns dynamically using hideColumn and showColumn public methods. We need call the methods with column header text as the method parameter.

The below code example explains about how to hide and show columns in Gantt:

<div id="GanttContainer" style="height:450px;width:100%"></div>
<button onclick="hide()" style="margin-top:10px">Hide column</button>
<button onclick="show()" style="margin-top:10px">Show column</button>
<script type="text/javascript">
$(function () {
            $("#GanttContainer").ejGantt({
                        //...
                taskIdMapping: "taskID",  
                startDateMapping: "startDate",
                load: function (args) {
                    var column = this.getColumns();
                    for (var i = 0; i < column.length; i++) {
                        //To hide the Start Date field
                        if (column[i].mappingName == "startDate") {
                            column[i].visible = false;
                        }
                    }
                }              
            })
        }); 
        function hide() {
            var ganttObj = $("#GanttContainer").data("ejGantt");
            //To Hide the Particular column
            ganttObj.hideColumn("ID");
        }
        function show() {
            var ganttObj = $("#GanttContainer").data("ejGantt");
            //To show the Particular column
            ganttObj.showColumn("Start Date");
        }            
</script>
