I am trying to add the index
value with my ids. but getting an error as:
Can't bind to 'testid' since it isn't a known property of 'input'.
here is my template:
<td *ngFor="let col of columns; let i = index" [ngClass]="col.class" data-testid="form-create-td-{{i}}">
what is wrong with my code? any one help me?
I think you will need property binding. So please try to replace below testid data property.
<td ... [attr.data-testid]="'form-create-td-' + i">
For concatenation id property with string, you are doing right thing.
