  entryComponents:[ UpdateAccountAttributesComponent],

  providers: [ AccountdetailService],
  bootstrap: [AppComponent]
})
export class AppModule { }

Here i have update the account.component.ts account.component.html and updateAccountAttributes.html files.

In the account.component.html file i have added a opendialog(row) method in the line below...

**<mat-row *matRowDef="let row; columns: displayedColumns1;" (click)="openDialog(row)"> </mat-row>**

I called this method in account.component.ts file and displayed the row data in console.

And opened this dialog with the updateAccountAttributes.html file...

I am able to fetch data in the dialog ... but how can i access the particular element data in my popup view ....

please help to resolve this...........
