columns: [
{ field: 'taskID', headerText: 'Task ID', width: 90, textAlign: 'Right' },

Grid row height for particular row can be customized using the rowDataBound event by setting the rowHeight in arguments for each row based on the requirement.
In the below example, the row height for the row with Task ID as ‘3’ is set as ‘90px’ using the rowDataBound event.
var treeGridObj = new ej.treegrid.TreeGrid({
dataSource: sampleData,
childMapping: 'subtasks',
height: 275,
rowDataBound: rowBound,
treeColumnIndex: 1,
columns: [
{ field: 'taskID', headerText: 'Task ID', width: 90, textAlign: 'Right' },
{ field: 'taskName', headerText: 'Task Name', width: 180 },
{
field: 'startDate', headerText: 'Start Date', width: 90, textAlign: 'Right', type: 'date',format: 'yMd'
},
{ field: 'duration', headerText: 'Duration', width: 80, textAlign: 'Right' }
]
});
treeGridObj.appendTo('#TreeGrid');
function rowBound(args) {
if(args.data.taskID === 3){
args.rowHeight = 90;
}
