First: you have to add [rowClass] to your grid

<kend-grid [rowClass]="rowCallback">
</kendo-grid>

then you need to add the function inside the component and return the needed class

public rowCallback(context: RowClassArgs) {
  if (context.dataItem.someProperty) {   // change this condition as you need
    return {
      passive: true
    };
  }
}  

and last you need to have a CSS class with the name you returned,(in this case passive but of course you can change it as you want)

@Component({
  selector: "your-component",
  templateUrl: "./your.component.html",
  encapsulation: ViewEncapsulation.None,
  styles: [
    `
     .k-grid tr.passive {
        background-color: lightgray;
      }

    `
  ]
})

it is very important to use encapsulation: ViewEncapsulation.None and name the class with the prefix .k-grid tr otherwise you will not get the needed result

Use the rowClass callback to provide a custom class to all rows whose data items meet some custom criteria, then style them via CSS, e.g.:

This will mark the rows with red background color if the above condition is met

<tr *ngFor="let myObject of myArray;" [ngStyle]="{'background-color':myObj.completedIn>24 ? 'red' : '' }">
   <!-- your other code -->
</tr>
