21 Dec 20221 minute to read

The autoFitColumns method resizes the column to fit the widest cell’s content without wrapping. You can autofit a specific column at initial rendering by invoking the autoFitColumns method in dataBound event.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" allowResizing="true" dataBound="ondataBound" childMapping="Children" treeColumnIndex="1">
        <e-treegrid-column field="TaskId" headerText="Task ID" textAlign="Right" width="90"></e-treegrid-column>
        <e-treegrid-column field="TaskName" headerText="Task Name" width="60"></e-treegrid-column>
        <e-treegrid-column field="StartDate" headerText=" Start Date" textAlign="Right" format="yMd" width="120"></e-treegrid-column>
        <e-treegrid-column field="Duration" headerText="Duration" textAlign="Right" width="120"></e-treegrid-column>
        <e-treegrid-column field="Progress" headerText="Progress" textAlign="Right" width="120"></e-treegrid-column>

    function ondataBound() {
        var treegridObj = document.getElementById("TreeGrid").ej2_instances[0];
public IActionResult Index()
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
