Hi Eric,

Thanks for contacting Infragistics!

To bind the combo's selected values with `[(ngModel)]`, you need to pass a reference to the entries inside of the combo's `data` input:

export class ComboMainComponent implements OnInit {
    public shoreData: any[];
    public arrayOfShores: any[];

    public ngOnInit() {
        this.shoreData = [
        { 'id': '#1 Post Shore', 'name': '#1 Post Shore'},
        { 'id': '#2 Post Shore', 'name': '#2 Post Shore'},
        { 'id': '#3 Post Shore', 'name': '#3 Post Shore'},
        { 'id': '#4 Post Shore', 'name': '#4 Post Shore'},
        { 'id': '#5 Post Shore', 'name': '#5 Post Shore'},
        { 'id': '#XL-350cm', 'name': '#XL-350cm'},
        { 'id': '#XL-480cm', 'name': '#XL-480cm'},
        { 'id': '#XL-625cm', 'name': '#XL-625cm'},
        { 'id': '6 feet Modular Alumn Shore', 'name': '6 feet Modular Alumn Shore'},
        { 'id': 'Stub Shore', 'name': 'Stub Shore'},
        { 'id': 'Customer Owned Shore', 'name': 'Customer Owned Shore'}];
        // set arrayOfShores to hold references to this.shoreData;
        this.arrayOfShores = [this.shoreData[0], this.shoreData[1], this.shoreData[2]];
    }
}

Here is a StackBlitz sample.

This will work with the latest version of our Angular library (currently, 8.1.3)

Please note that there is an open issue in our Angular Repo that, once addressed, will introduce a **breaking change** to the way the combo is bound to data. When the fix is in place, you can just remove the `[valueKey]` input and everything should work properly.

I hope this was helpful!
