Restrict decimal points while treegrid editing in EJ2 JavaScript Treegrid control

27 Apr 20235 minutes to read

By default, the number of decimal places will be restricted to two in the NumericTextBox while editing the numeric column. We can restrict to type the decimal points in a NumericTextBox by using the validateDecimalOnType and decimals properties of NumericTextBox.

In the below demo, while editing the row we have restricted to type the decimal point value in the NumericTextBox of Price column.

import { TreeGrid, Edit, Toolbar } from "@syncfusion/ej2-treegrid";
import { stackedData } from './datasource.ts';

TreeGrid.Inject(Edit, Toolbar);

let treegrid: TreeGrid = new TreeGrid({
  dataSource: stackedData,
  childMapping: "subtasks",
  treeColumnIndex: 1,
  height: 265,
  editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true },
  toolbar: ["Add", "Delete", "Update", "Cancel"],
  columns: [
    { field: "orderID", headerText: "Order ID", textAlign: "Right", isPrimaryKey: true, width: 70 },
    { field: "orderName", headerText: "Order Name", width: 100 },
    { field: "orderDate", headerText: "Order Date", textAlign: "Right", width: 100, editType: "datepickeredit",
      format: { skeleton: "yMd", type: "date" } },
    { field: "shippedDate", headerText: "Shipped Date", textAlign: "Right", width: 100,
      editType: "datepickeredit", format: { skeleton: "yMd", type: "date" } },
    { field: "shipMentCategory", headerText: "Shipment Category", textAlign: "Right", width: 100 },
    { field: "units", headerText: "Units", width: 90, editType: "numericedit" },
    { field: "price", headerText: "Price", width: 90, editType: "numericedit",
      edit: {
        params: {
          validateDecimalOnType: true,
          decimals: 0,
          format: "N"
        }
      }
    }
  ]
});
treegrid.appendTo("#TreeGrid");
