Row cell customization in EJ2 TypeScript Treegrid control
27 Apr 20235 minutes to read
In Tree Grid we can customize the row and cell using queryCellInfo
and rowDataBound
events of Tree Grid.
In the below demo, we customize and show the command buttons only for the parent rows using queryCellInfo
and rowDataBound
events of Tree Grid.
import { TreeGrid, CommandColumn, Column, ITreeData } from "@syncfusion/ej2-treegrid";
import { sampleData } from './datasource.ts';
import { QueryCellInfoEventArgs, RowDataBoundEventArgs } from "@syncfusion/ej2-grids";
TreeGrid.Inject(CommandColumn);
let treegrid: TreeGrid = new TreeGrid({
dataSource: sampleData,
childMapping: "subtasks",
treeColumnIndex: 1,
height: 280,
rowDataBound: rowDataBound,
queryCellInfo: queryCellInfo,
columns: [
{ field: "taskID", headerText: "Task ID", isPrimaryKey: true, width: 80, textAlign: "Right" },
{ field: "taskName", headerText: "Task Name", width: 200 },
{ field: "startDate", headerText: "Start Date", textAlign: "Right", width: 90,
format: { skeleton: "yMd", type: "date" } },
{ field: "endDate", headerText: "End Date", textAlign: "Right", width: 90,
format: { skeleton: "yMd", type: "date" } },
{ field: "duration", headerText: "Duration", textAlign: "Right", width: 90 },
{ field: "progress", headerText: "Progress", width: 90 },
{ headerText: "Commands", width: 120,
commands: [
{
buttonOption: {
content: "Details",
cssClass: "e-flat"
}
}
]
}
]
});
treegrid.appendTo("#TreeGrid");
function rowDataBound(args: RowDataBoundEventArgs) {
if (!(args.data as ITreeData).hasChildRecords) {
(args.row as HTMLElement).style.backgroundColor = "green";
}
}
function queryCellInfo(args: QueryCellInfoEventArgs) {
if (!(args.data as ITreeData).hasChildRecords) {
if ((args.cell as HTMLElement).classList.contains("e-unboundcell")) {
((args.cell as HTMLElement).querySelector(
".e-unboundcelldiv"
) as HTMLElement).style.display = "none";
}
}
}
