Wajeeh Hasan, could you please expand on your last statement:

Last, Do a API call and save that data into this _person.

I was able to create the model, add the scoped service and inject into the parent component, but when I inject into child component the value is null.

This is the command I used to set the variable in the parent component. _studentpass.studentId = Convert.ToString(studentId);

I used the following in the child component, and it was null. studentId = _studentpass.studentId
