Discovering and Implementing Background Color Adjustments for Recently Modified or Added Rows with Errors or Blank Cells in a dx-data-grid

What is the process for detecting and applying background color changes to the most recently added or edited row in a dx-data-grid for Angular TS if incorrect data is entered in a cell or if there are empty cells?

<dx-data-grid
  [dataSource]="dataSource"
  keyExpr="id"
  (onRowInserted)="onRowInserted($event)"
  (onRowUpdating)="onRowUpdating($event)"
  (onRowInserting)="onRowInserting($event)"
  (onRowUpdated)="onRowUpdated($event)">
  <!-- Defined columns and other configurations -->
</dx-data-grid>

If the user enters incorrect or empty values during onRowUpdating and onRowInserting, they will not be able to exit editing mode and the background of that row will turn red.

The Devextreme data grid comes with its own validation API that can be used to validate data.

To see a demo of the data grid validation, you can visit this link.

Here is an example of how to set up validation for a column:

 <dxi-column dataField="Phone">
    <dxi-validation-rule type="required"></dxi-validation-rule>
    <dxi-validation-rule
      type="pattern"
      [pattern]="pattern"
      message="Your phone must have &#34;(555) 555-5555&#34; format!"
    ></dxi-validation-rule>
  </dxi-column>
