Prevent Editing for Specific Fields

The Grid allows you to restrict users from editing specific fields. This is suitable when you want some columns to stay the same, while still letting users edit the rest of the information.

To prevent editing specific cells, you can use any of the following approaches:

• Disable editing for selected fields, such as IDs or company names, by setting the built-in editable option of the respective column(s) to false.

  Copy Code<kendo-grid ... >
      <kendo-grid-column field="ProductID" [editable]="false"></kendo-grid-column>
      ...
  </kendo-grid>

• Omit the field(s) declaration in the FormGroup.

  Copy Codepublic createFormGroup(dataItem: any): FormGroup {
      return this.formBuilder.group({
          // 'ProductID': dataItem.ProductID,
          'UnitPrice': dataItem.UnitPrice,
          'UnitsInStock': [dataItem.UnitsInStock, Validators.compose([Validators.required, Validators.pattern('^[0-9]{1,3}')])],
          'Discontinued': dataItem.Discontinued
      });
  }

• Skip the editCell method invocation in the cellClick event handler.

  Copy Codepublic cellClickHandler({ sender, column, rowIndex, columnIndex, dataItem, isEdited }) {
      if (!isReadOnly(column.field)) {
          sender.editCell(rowIndex, columnIndex, this.createFormGroup(dataItem));
      }
  }

The following example demonstrates the complete implementation of the cellClick event-handler approach.
