I'm developing aspnetzero application with angular but when I'm assigning value of categories property in p-dataTable I'm getting this error in browser console: Can't bind to 'value' since it isn't a known property of 'p-dataTable' I have three files. First file categories.component.ts import { Component, Injector, OnInit } from '@angular/core'; import { AppComponentBase } from '@shared/common/app-component-base'; import { appModuleAnimation } from '@shared/animations/routerTransition'; import { Http, Response, Headers, RequestOptions } from "@angular/http"; import { AppSessionService } from '@shared/common/session/app-session.service'; import { Category } from './category'; import { DataTableModule, SharedModule, DataTable } from 'primeng/primeng'; @Component({ templateUrl: './categories.component.html', animations: [appModuleAnimation()] }) export class CategoriesComponent extends AppComponentBase implements OnInit { categories: Category[]; constructor( injector: Injector, private http: Http, private appSessionService: AppSessionService ) { super(injector); } ngOnInit(): void { this.getCategories(); } getCategories(): void { let headers = new Headers({ 'Content-Type': 'application/json' }) headers.append('tenantId', this.appSessionService.tenant ? this.appSessionService.tenant.id.toString() : '-1'); let options = new RequestOptions({ headers: headers }); this.http.get('/api/categories', options).subscribe(values => { this.categories = values.json(); }); } } Second categories.component.html <div [@routerTransition]> <div class="row margin-bottom-5"> <div class="col-xs-12"> <div class="page-head"> <div class="page-title"> <h1> <span>{{l("Categories")}}</span> </h1> </div> </div> </div> </div> <div class="portlet light margin-bottom-0"> <div class="portlet-body"> <p-dataTable [value]="categories"> <p-column field="category.Name" header="Category"></p- column> </p-dataTable> </div> </div> </div> and Category class export class Category { constructor( public id: number, public name: string) { } } This is app.module.ts import { NgModule } from '@angular/core'; import * as ngCommon from '@angular/common'; import { FormsModule } from '@angular/forms'; import { HttpModule, JsonpModule } from '@angular/http'; import { ModalModule, TooltipModule, TabsModule } from 'ngx-bootstrap'; import { FileUploadModule } from '@node_modules/ng2-file-upload'; import { AppRoutingModule } from './app-routing.module'; import { AppComponent } from './app.component'; import { HeaderComponent } from './shared/layout/header.component'; import { HeaderNotificationsComponent } from './shared/layout/notifications/header-notifications.component'; import { SideBarComponent } from './shared/layout/side-bar.component'; import { FooterComponent } from './shared/layout/footer.component'; import { LoginAttemptsModalComponent } from '@app/shared/layout/login-attempts-modal.component'; import { ChangePasswordModalComponent } from '@app/shared/layout/profile/change-password-modal.component'; import { ChangeProfilePictureModalComponent } from '@app/shared/layout/profile/change-profile-picture-modal.component'; import { MySettingsModalComponent } from '@app/shared/layout/profile/my-settings-modal.component'; import { SmsVerificationModalComponent } from '@app/shared/layout/profile/sms-verification-modal.component'; import { AbpModule } from '@abp/abp.module'; import { UtilsModule } from '@shared/utils/utils.module'; import { AppCommonModule } from './shared/common/app-common.module'; import { ServiceProxyModule } from '@shared/service-proxies/service-proxy.module'; import { ImpersonationService } from './admin/users/impersonation.service'; import { LinkedAccountService } from './shared/layout/linked-account.service'; import { LinkedAccountsModalComponent } from '@app/shared/layout/linked-accounts-modal.component'; import { LinkAccountModalComponent } from '@app/shared/layout/link-account-modal.component'; import { NotificationsComponent } from './shared/layout/notifications/notifications.component'; import { NotificationSettingsModalCompoent } from './shared/layout/notifications/notification-settings-modal.component'; import { UserNotificationHelper } from './shared/layout/notifications/UserNotificationHelper'; import { ChatBarComponent } from './shared/layout/chat/chat-bar.component'; import { ChatFriendListItem } from './shared/layout/chat/chat-friend-list-item.component'; import { ChatSignalrService } from '@app/shared/layout/chat/chat-signalr.service'; import { QuickSideBarChat } from '@app/shared/layout/chat/QuickSideBarChat'; import { DataTableModule } from 'primeng/primeng'; import { PaginatorModule } from 'primeng/primeng'; @NgModule({ declarations: [ AppComponent, HeaderComponent, HeaderNotificationsComponent, SideBarComponent, FooterComponent, LoginAttemptsModalComponent, LinkedAccountsModalComponent, LinkAccountModalComponent, ChangePasswordModalComponent, ChangeProfilePictureModalComponent, MySettingsModalComponent, SmsVerificationModalComponent, NotificationsComponent, ChatBarComponent, ChatFriendListItem, NotificationSettingsModalCompoent ], imports: [ ngCommon.CommonModule, FormsModule, HttpModule, JsonpModule, ModalModule.forRoot(), TooltipModule.forRoot(), TabsModule.forRoot(), FileUploadModule, AbpModule, AppRoutingModule, UtilsModule, AppCommonModule.forRoot(), ServiceProxyModule, DataTableModule, PaginatorModule ], providers: [ ImpersonationService, LinkedAccountService, UserNotificationHelper, ChatSignalrService, QuickSideBarChat ] }) export class AppModule { } Continue reading...
