Md-Select start value or active value

[dahaupt]

Bug, feature request, or proposal:

Feature request

What is the expected behavior?

The Md-Select-Component should be able to have a start value, which should remain active even after the page has been reloaded.

After reloading or switching routes I wanna see it like this:

What is the current behavior?

We can't set a start value for select. We can click a button to set it, but there is no attribute available to bind it directly with a variable.

What are the steps to reproduce?

Look into existing select examples and try to set a startup value.

Which versions of Angular, Material, OS, browsers are affected?

Angular Material latest version (from master)

Is there anything else we should know?

I am not sure if I just don't see the way to do it or if it's already planned for the future.

Hi, md-select has not been released yet.
Please see https://github.com/angular/material2/blob/master/README.md.

Will be released in alpha.11

@bastienlemaitre Hi, I am aware of that, but alpha.11 is already the next version and I can't find any plans (md-select in projects) to realize this feature.

@kara & @jelbourn, Just a question around the release date of the Alpha 11. Will this be in November or are we looking at December for this one? Would like to use md-select but if I can't will write my own.

Thanks in advance.

We don't yet have an exact date for the next release.

[seanrkerr]

ok, no worries.

@dahaupt I don't quite follow- is this not just the value property of the select?

[kara]

@dahaupt The select is a custom value accessor, so you should be able to use ngModel or any other available form directive in Angular 2.

<md-select [(ngModel)]="food"></md-select>

[dahaupt]

@kara & @jelbourn This would lead me to set the value with a FormControl object for example. Let's stay in the demo-app select example:

foodControl = new FormControl('pizza-1');

This should set a start value of the md-select component. But even if the value is right now, I can just see the placeholder:

This button works fine:

<button md-button (click)="foodControl.setValue('pizza-1')">SET VALUE</button>

How can I achieve that in the TypeScript of my component before? What am I doing wrong?

[kara]

@dahaupt Aha! Okay, I see what you're talking about, thanks for clarifying. While setting the initial value using ngModel does work, setting an initial value using formControl doesn't yet because the value is written synchronously before the options exist. I'm submitting a quick fix that should make the code above work. When the select component is released, the fix should go out with it.

@kara Thanks and keep up the great work! 👍
