How to hide a specific task bar in Gantt
You can hide the specific taskbar in both project and resource allocation views in Gantt. This can be done by using queryTaskbarInfo client side event, which will be triggered for each taskbar being rendered in Gantt.
The below code example explains how to hide task bars based on task ID in resource allocation view in Gantt.
<script type="text/javascript">
$(function () {
$("#resourceGantt").ejGantt({
dataSource: resourceGanttData,
taskIdMapping: "taskID",
queryTaskbarInfo: function (args) {
var taskbarElement = args.taskbar;
if (args.data.eResourceTaskType == "resourceChildTask") {
if (args.data.taskId == 1 || args.data.taskId == 4) {
$(taskbarElement).css("display", "none");
}
}
},
//..
});
});
</script>
