Toggle selection

The Toggle selection allows to perform selection and unselection of the particular row or cell. To enable toggle selection, set enableToggle property of the selectionSettings as true. If you click on the selected row or cell then it will be unselected and vice versa.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" allowPaging="true" allowSelection="true" childMapping="Children" treeColumnIndex="1">
     <e-treegrid-selectionsettings enableToggle="true" type="Multiple"></e-treegrid-selectionsettings>
        <e-treegrid-column field="TaskId" headerText="Task ID" textAlign="Right" width="100"></e-treegrid-column>
        <e-treegrid-column field="TaskName" headerText="Task Name" width="190"></e-treegrid-column>
        <e-treegrid-column field="StartDate" headerText=" Start Date" textAlign="Right" format="yMd" type="date" width="120"></e-treegrid-column>
        <e-treegrid-column field="Duration" headerText="Duration" textAlign="Right" width="110"></e-treegrid-column>
public ActionResult Index()
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();


If multi selection is enabled, then first click on any selected row (without pressing Ctrl key), it will clear the multi selection and in second click on the same row, it will be unselected.
