In Gantt, we can hide or show the columns using hideColumn and showColumn public methods. We need to call these methods using the column’s header text as parameter. It is not possible to hide the tree/expander column by default. The following code snippet explains how to hide/show the column at an external button click event. <button id="hidecolumn">Hide Task Name field</button>
<button id="showcolumn">Show Task Name field</button>
<div id="gantt" style="position: absolute; height:550px; width:1300px"></div>
<script type="text/javascript">
$(function () {
$("#gantt").ejGantt({
treeColumnIndex:3,
//...
});
});
$("#hidecolumn").click(function () {
var ganttObj = $("#gantt").data("ejGantt");
ganttObj.hideColumn("Task Name");
});
$("#showcolumn").click(function () {
ganttObj = $("#gantt").data("ejGantt");
ganttObj.showColumn("Task Name")
});
</script>
