Hi Sunithra, 

Greetings from Syncfusion support. 

We can achieve your requirement using the rowSelected, rowDeselected event of Grid. 

Refer the below code example. 

[app.component.html] 

<ejs-dropdownlist id='games' #dropdown width='150px' [dataSource]='sportsData' [value]='value' [fields]='fields' [placeholder]='waterMark' [popupHeight]='height'></ejs-dropdownlist> 

 

<ejs-grid [dataSource]='data' #grid allowPaging='true' (rowSelected)='rowSelected($event)' (rowDeselected)='rowDeselected($event)' [enableHover]="false" [allowSelection]="true" [selectionSettings]="selectOptions"> 

  <e-columns> 

    <e-column type='checkbox' width='50'></e-column> 

    <e-column field='OrderID' isPrimaryKey='true' headerText='Order ID' width='120' textAlign='Right'></e-column> 

    <e-column field='CustomerName' headerText='Customer Name' width='150'></e-column> 

    <e-column field='OrderDate' headerText='Order Date' width='130' format="yMd" textAlign='Right'></e-column> 

    <e-column field='Freight' headerText='Freight' width='120' format='C2' textAlign='Right'></e-column> 

    <e-column field='ShippedDate' headerText='Shipped Date' width='130' format="yMd" textAlign='Right'></e-column> 

  </e-columns> 

</ejs-grid> 

---------------------------------------------------------------------------------------- 

[app.component.ts] 

export class AppComponent { 

  @ViewChild('dropdown') 

  public dropdownObj: DropDownListComponent; 

  @ViewChild('grid') 

  public gridObj: GridComponent; 

   

    ---- 

 

  public ngOnInit(): void { 

    this.data = orderDetails; 

    this.selectOptions = { persistSelection: true }; 

  } 

  rowSelected(args) { 

    if (this.gridObj.getSelectedRowIndexes().length >= 2) { 

      this.dropdownObj.enabled = true; 

    } 

    else { 

      this.dropdownObj.enabled = false; 

    } 

  } 

  rowDeselected(args) { 

    if (this.gridObj.getSelectedRowIndexes().length < 2) { 

      this.dropdownObj.enabled = false; 

    } 

  } 

} 

We have prepared a simple sample in the following stackblitz link.
