Customize cell styles

The appearance of cells can be customized by using the queryCellInfo event. The queryCellInfo event triggers for every cell. In that event handler, you can get QueryCellInfoEventArgs that contains the details of the cell.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" queryCellInfo="customizeCell" height="300" childMapping="Children" treeColumnIndex="1">
        <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="Duration" headerText="Duration" textAlign="Right" width="110"></e-treegrid-column>
        <e-treegrid-column field="Progress" headerText="Progress" textAlign="Right" width="110"></e-treegrid-column>

    function customizeCell(QueryCellInfoEventArgs) {
        var args = QueryCellInfoEventArgs;
        if (args.column.field === 'Progress' && args.cell.innerHTML > 90 && args.cell.innerHTML <= 100) {
            args.cell.setAttribute('style', 'background-color:#336c12;color:white;');
        } else if (+args.cell.innerHTML > 20 && args.column.field === 'Progress') {
            args.cell.setAttribute('style', 'background-color:#7b2b1d;color:white;');
public IActionResult Index()
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
