Answer №1

When setting a value to the selectedEmployeeCountRadioButton in *ngIf, remember this:

Use

<tr *ngIf = "selectedEmployeeCountRadioButton=='All' || selectedEmployeeCountRadioButton==employ.gender"></tr>

Avoid using

<tr *ngIf = "selectedEmployeeCountRadioButton=='All' || selectedEmployeeCountRadioButton=employ.gender"></tr>
