Customize the edit dialog in EJ2 TypeScript Treegrid control
27 Apr 20235 minutes to read
You can customize the appearance of the edit dialog in the actionComplete
event based on requestType as beginEdit or add.
In the below example, we have changed the dialog’s header text for editing and adding records.
import { TreeGrid, Toolbar, Edit } from "@syncfusion/ej2-treegrid";
import { projectData } from './datasource.ts';
import { DialogEditEventArgs } from "@syncfusion/ej2-grids";
import { Dialog } from "@syncfusion/ej2-popups";
TreeGrid.Inject(Toolbar, Edit);
let treegrid: TreeGrid = new TreeGrid({
dataSource: projectData,
idMapping: "TaskID",
parentIdMapping: "parentID",
treeColumnIndex: 1,
height: 250,
editSettings: {
allowAdding: true,
allowEditing: true,
allowDeleting: true,
mode: "Dialog"
},
toolbar: ["Add", "Edit", "Delete", "Update", "Cancel"],
actionComplete: actionComplete,
columns: [
{ field: "TaskID", headerText: "Task ID", isPrimaryKey: true, textAlign: "Right", width: 70 },
{ field: "TaskName", headerText: "Task Name", width: 100 },
{ field: "StartDate", headerText: "Start Date", textAlign: "Right", width: 90, editType: "datepickeredit",
format: { skeleton: "yMd", type: "date" }, edit: { params: { format: "y/M/d" } } },
{ field: "EndDate", headerText: "End Date", textAlign: "Right", width: 90, editType: "datepickeredit",
format: { skeleton: "yMd", type: "date" }, edit: { params: { format: "y/M/d" } } },
{ field: "Duration", headerText: "Duration", textAlign: "Right", width: 90 },
{ field: "Priority", headerText: "Priority", width: 90 }
]
});
treegrid.appendTo("#TreeGrid");
function actionComplete(args: DialogEditEventArgs) {
if (args.requestType === "beginEdit" || args.requestType === "add") {
const dialog = args.dialog as Dialog;
const TaskName = "TaskName";
dialog.height = 400;
// change the header of the dialog
dialog.header =
args.requestType === "beginEdit"
? "Record of " + args.rowData[TaskName]
: "New Customer";
}
}
