FormControl display value
How to display some text in input FormControl that not equal to value of this FormControl?
For example, get some object from a server - {id: 1, name: "Name1"}
, and set value
of FormControl to that object or to object.id but display value
set to object.name - "Name1".
Why i need it:
I use angular material autocomplete and it set the value of FormControl to object (from selected mat-option) and display value to string via displayWith. I want to repeate this behavior when fetch data from server for some consistency and convenience

I do some research for my question.
It is need to use FormControlDirective and its valueAccessor.writeValue()
for set display value of input (it use renderer) or as alternative nativeElement.value
.
And FormControl's setValue()
with emitModelToViewChange = false
for set FormControl value.
In template
<input [formControl]="ctrlF" #ctrlD="ngForm">
In controller
@ViewChild('ctrlD', {read: FormControlDirective})
ctrlD :FormControlDirective
...
this.ctrlD.valueAccessor.writeValue("display value")
this.ctrlD.control.setValue({foo: "foo", bar: "bar"}, {
emitModelToViewChange: false
})
