I am getting this error from Chrome when running an ag-grid application. Basically, I have following

export class CustomHeader implements IHeaderAngularComp {
  private params: any;


  @ViewChild('menuButton', { read: ElementRef }) public menuButton;

  agInit(params): void {
    this.params = params;
  }

  onMenuClicked() {
    this.params.showColumnMenu(this.menuButton.nativeElement);
  }

  refresh(params: IHeaderParams): boolean {
    return true;
  }
}

...

ColumnDefs = {
    ...
     {
        field: "A column", editable: false, sortable: false, width: 90,
        type: 'stringColumn', centered: true, pinned: 'left',
        headerComponent: CustomHeader,
        headerComponentParams: {
          template: `
            <div ref="eLabel" class="lmn-form-group">
              <input ref="eCheck" type="checkbox">
              <span>Use This</span>
            </div>
          `
        }
     },
    ...
}

The Chrome says it does not recognize this CustomHeader:

Could not find ponent class CustomHeader { agInit(params) { this.params = params; } onMenuClicked() { this.params.showColumnMenu(this.menuButton.nativeElement); } refresh(params) { return true; } }, did you forget to configure this ponent?"

Is there anything I am missing?

• Is there a @Component decorator on it? – Aviad P. Commented Jul 29, 2021 at 6:03

Have you seen the example in the documentation?

Note that you also need to provide the [frameworkComponents] grid property so that the grid knows to use the header ponent:

 this.frameworkComponents = { agColumnHeader: CustomHeader };

If you e here in 2022 and you are not using the latest version ag-grid, do check the correct version documents here:

https://www.ag-grid./archive/

For me at version 25.3, still need to use frameworkComponents as @Shuheb said, but the latest version 27.3 docs do not have this property any more.

As the 25.3 doc says, There are two ways to register custom ponents:

• By name.
• Direct reference.

1. By Name

export class AppComponent {
  frameworkComponents: [
      'cubeComponent': CubeComponent
  ];          
  columnDefs: [
      {
          headerName: "Cube",
          field: "value",
          cellRenderer: 'cubeComponent',     
      }
  ]

  //...other properties & methods
}

2. By Direct Reference

export class AppComponent {
  columnDefs: [
      {
          headerName: "Cube",
          field: "value",
          cellRendererFramework: CubeComponent,     
      }
  ]

  //...other properties & methods
}
