Dynamically assigning drop down value

I have ion grid, when press add method function; the ion-row gets append into existing ion grid. However when I change the ion-select value inside the ion-row, all the ion-row value gets changed to current selected value despite of changing the specific ion-row column drop down value.

Generally speaking (since you haven’t posted any code), the following structure is virtually always a mistake:

<div *ngFor="let foo of foos">
  <control [(ngModel)]="bar">
</div>

bar is an object property of the controller, so all the controls will be aliased. Ordinarily, you want this instead:

<div *ngFor="let foo of foos">
  <control [(ngModel)]="foo.bar">
</div>

This way each control has a dedicated backing property on each foo.

I was able to solve as above…thanks for the reply.
