Angular @ngrx/entity Use

[GaryParticipant]

I have been using @NGRX/Entities for store support in my Angular 6 application, and I was wondering if it is possible to use an observable entity as an Observable Array for input into JGXGRID.

I see that an Observable Array is available in the jqxDataAapter. However, I think this is for Knockout.js.

I have not tried but, before going down that path, I was hoping somebody might have experience in this area.

Thanks in advance for any info.

Best Regards,
Gary

Hello Gary,

Observable Arrays are supported also in jqxGrid. You can see a Demo about this here.

Unfortunately, we do not have experience with @NGRX/Entities. You can try it and contact us again, if you have any problem with it.

Hello Martin,
I just spent several days taking on trying to get NGRX/Entity observable output work as input to jqxGrid.

I believe the difference exists with the Observable design of RX/JS and how JQWIDGETS define an observable. I did some research on Knockout vs. RX/JS, and clearly some similarities but different approached to the observable structure. Might be better to say Knockout is a framework with bells and whistles to UI management. Were as RX/JS is an observable establishing data stream management. If I couple the RX/ JS, NG/RX/Store, and NG/RX/Entity and UI feature capabilities provided by Angular 6, I can start to see a closer relationship between Knockout and let’s say Angular Store solution.

However, to take a pure RX/JS Observable and plug it in for a data source for jqxGrid it did not cause an error but, just no data appeared in the grid.

Here is the definition I used for source:

// Accounts$: Observable<Account[]>;  RX/js observable

// localdata: this.accounts$,
// datatype: ‘obserableArray,
// datafields: [
// {name: ‘AcctName’, type: ‘string’},
// {name: ‘AcctCategory’, type: ‘string’},
// {name: ‘AcctType’, type: ‘string’},
// {name: ‘AcctNumber’, type: ‘string’},
// {name: ‘AcctOpenDate’, type: ‘date’},
// {name: ‘AcctDescription’, type: ‘string’},
// {name: ‘AcctBalance’, type: ‘number’},
// {name: ‘AcctStatus’, type: ‘bool’}
// ],
// id: ‘_id’,

If I can provide you with something, let me know.

I’ll put in a formal request to add RX/JS as an observable data source for jqxGrid, jqxChart and, jqxPivotGrid etc.…. for a future release.

Thanks,
Gary
