What is the process for refreshing the dropdown menu in angular2 after modifying the data in the typescript file?

Right now, I am implementing angular2 in my project. I have a dropdown component labeled as

CFC Filter {{val}}

In the typescript file, I have defined this.filters = ["0", "60", "100", "180", "600", "1000"];

If the filter value retrieved from the database is 1000, how can I dynamically set that value in the dropdown whenever new data is fetched from the DB?

Answer №1

To utilize the model variable in the component, simply assign a value to it like this:

this.channelPropertyModel.filterValue = "1000";

Ensure that you have also declared the variable beforehand:

channelPropertyModel.filterValue: string;
