Using Subject u can try

SAGO

@SAGOlab

Inside a dialog have a task status that display a value get from a REST API (the task status is: Ready) and a button ('start task'). On click 'start task' I need to change task status value, so I need to get the new REST API response, get task status 'In progress' and display it in Dialog, without close it...

there are other way apart from Subject?

has anyone had any issues running the spec file from the material:navigation schematic? Error: Can't resolve all parameters for <name-of-component>: (?). wherein the concerned constructor parameter is BreakpointObserver. I’ve tried injecting on the spec file, still doesn’t resolve any. I am using v10 of Angular and Angular/Material

Oh, found a solution. I used Jest over Jasmine, Karma and forgot to add this on in the tsconfig.spec.json - "emitDecoratorMetadata": true,

Hey all. Is it possible to customize the padding values of e.g. angular material buttons? I see that there is a variable called $mat-button-padding in the _button-base.scss of angular material. Is there a possibility to change this value?

hi all, i'm trying to write a cypress routine to handle drag and drop that uses cdk drag and drop (https://material.angular.io/cdk/drag-drop/overview)

i can get cypress to the point of holding the drag preview over the droplist target but the drop preview is not materializing

can anyone give me a clue as to what specific element needs to receive a mouseover event for that drop preview to appear?

Hi all, How can I resize the height of the mat-tree dynamically. I would like mat-tree to take the full height of the container without using vh unit (because vh does not work very well with mobile/tablet devices).

Hi, I think I am missing something basic. I am trying to build a reusable table component based on MatTable. I am moving the column definition to a column to contain multiple properties, starting with name, label, and eventually actions and other attributes. Does MatTable support working with objects? Or does it only support working with arrays of strings? Here is a simple stackblitz I built off the MatTable simple demo with the sample above my re-usable component (which shows zero rows). https://stackblitz.com/edit/angular-jr1gcs?file=src/app/table.component.html

Bala_github

@GitHubBala23

Hi Timothy, if u want to show objects data , u might wanna seperate out use a fun call in that col definition nd then in .ts return it as an array

Timothy Spear

@n614cd

@GitHubBala23 I am not even at the point of showing object data. For the moment, I am using a simple text area. What I am trying to do is use an object to define the column. e.f. the label for the column header, the name of the field in the array....

Bala_github

@GitHubBala23

ohk u want to build a resuable Mat data table component ??

Timothy Spear

@n614cd

yes

Timothy Spear

@n614cd

Adding a ViewChild to find the MatTable, I can see that the table is aware of the data. However, nothing is rendered under the TBODY element.

anyone have suggestions?

React Specialist

@AcodeWizard

As far as I am concerned, you may use the ViewChild ref to the MatTable in the wrong place of ts file. As you know, the ViewChild ref is be initialized in ngAfterViewInit lifecycle. That's why you can access the ref to the MatTable in that lifecycle. If you share the source with me, I can guide you in more detailed way. Thank you.

Hey, has anyone built an apply (submit) style of select component?
I've a multi select that I'd like to only take on apply, rather than as each option is selected.

It feels oddly complex to implement, like I have to maintain a selected field on each option and then apply them on submit?

Have tried to phrase it as a fuller question here: https://stackoverflow.com/questions/64603629/angular-select-how-to-have-a-multi-select-with-an-apply

Hi ppl, I just upgraded my app to angular 10
so far so good
there is one lint warning and a deprecation notice that I'm not sure how to resolve
it seems PortalInjector was deprecated
I'm not really sure how to migrate this snippet

private createInjector(config: ModalConfig, dialogRef: ComponentModalRef): PortalInjector {
    const injectionTokens = new WeakMap();

    injectionTokens.set(ComponentModalRef, dialogRef);
    injectionTokens.set(COMPONENT_MODAL_DATA, config.data);
    return new PortalInjector(this.injector, injectionTokens);
  }

to use Injector.create

<mat-form-field appearance="outline" class="example-full-width">

<mat-label>Service Charges</mat-label>

<mat-select placeholder="Service Charge" [formControl]="serviceCharges" multiple>

<mat-select-trigger>

<mat-chip-list>

<mat-chip *ngFor="let charge of serviceCharges" [removable]="true" (removed)="onServiceChargeRemoved(charge)">
{{ charge.rate }}

<mat-icon matChipRemove>cancel</mat-icon>

<mat-option *ngFor="let serviceCharge of serviceChargeLists" [value]="serviceCharge.rateId" [rate]="serviceCharge.rate">
<span>{{serviceCharge.activityDesc}}</span>
<span class="float-right">({{serviceCharge.rate}})</span>
</mat-option>
</mat-select>

How can I bind the array value in mat chip ex: I want to bind {{serviceCharge.rate}} in mat chip ?

Question: Is there any way to track the Q4 goals that were stated on the README?
https://github.com/angular/components#what-were-working-on-now-q4-2020

In particular I'm curious about the new density theming api: "Introduce a new theming API for component density, a top feature request."

Wai Liu

@waiholiu

Hi all, stupid question... is the documentation website (https://material.angular.io) actually stored in the github repo? I can't seem to find it anywhere. The reason I ask is there is a couple of really nice things on that website that I'd like to take a look at the source code to see how it is done. Can someone point me to where in the repo it is?

@Splaktar

@Waterstraal There are some references in https://github.com/angular/components/blob/master/guides/duplicate-theming-styles.md. If you want to dig into it some more, you can dig into some of these files: https://github.com/angular/components/search?q=density. Hopefully some docs on this will be coming soon.

Michael Prentice

@Splaktar

@Waterstraal update on this, the density docs will be coming when the MDC versions of the components are released. For now density only works on the material-experimental versions of the components (and a few material components that don’t have MDC versions).
