It is possible to show or hide columns dynamically in TreeGrid using hideColumn and showColumn public methods. We need to pass the column header text as the method parameter.
The below code example explains about how to hide and show columns in TreeGrid <div id="TreeGridContainer" style="height:400px;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 () {
$("#TreeGridContainer").ejTreeGrid({
//
dataSource: projectData,
columns: [
{ field: "taskID", headerText: "Task Id", editType: "numericedit", width: "60" },
{ field: "taskName", headerText: "Task Name", editType: "stringedit" },
{ field: "startDate", headerText: "Start Date", editType: "datepicker" },
{ field: "endDate", headerText: "End Date", editType: "datepicker",visible:false},
{ field: "duration", headerText: "Duration", editType: "numericedit" },
{ field: "progress", headerText: "Progress", editType: "numericedit" }
]
})
});
function hide() {
var treeObj = $("#TreeGridContainer").data("ejTreeGrid");
//To Hide the Particular column
treeObj.hideColumn("Task Id");
}
function show() {
var treeObj = $("#TreeGridContainer").data("ejTreeGrid");
//To show the Particular column
treeObj.showColumn("End Date");
}
</script>
