In my app, I have a table with multiple columns. I'm trying to fill it with the respected data but when the page opens I get the error Could not find column with id "PublishedParty" yet, it's in the TS file. Here is my code, what is wrong with it?
HTML:
<ng-container *ngIf="isPublishedParty == true" matColumnDef="PublishedParty">
<th mat-header-cell *matHeaderCellDef mat-sort-header style="min-width: 100px !important;" [ngStyle]="{'color': 'black'}" style="text-align: center;">
<b>
Planlanan Miktar
</b>
</th>
<td mat-cell *matCellDef="let row; let i = index" style="min-width: 100px !important;" style="text-align: center;">
<div>
Miktar: {{row.PublishedPartyQuantity | number}}
</div>
<div>
Parti: {{row.PublishedPartyCount | number}}
</div>
</td>
</ng-container>
TS:
isPublishedParty = false;
private _materialPlan: IMaterialPlan = {};
@Input()
set MaterialPlan(prm: IMaterialPlan){
this._materialPlan = prm;
}
get MaterialPlan(): IMaterialPlan {
return this._materialPlan;
}
displayedColumns: string[] = [
'StockIntegrationCode',
'ReceiptName',
'PublishedParty',
];
dataSource: MatTableDataSource<IMaterialPlanReceiptResult>;
@ViewChild(MatPaginator, { static: true }) paginator: MatPaginator;
@ViewChild(MatSort, { static: true }) sort: MatSort;
constructor(
) {
if(this._materialPlan.IncludePlannedParty == true){
this.isPublishedParty == true;
}
}
For angular to render the table correctly isPublishedParty should be initialized as true. Otherwise *ngIf removes it from the template and you would get such an error. You could set isPublishedParty to false at later time, perhaps in ngAfterViewInit() cycle.
I think, the problem is, that you hide the ng-container when the condition in your constructor is false for "this._materialPlan.IncludePlannedParty".
So the solution could be, to remove the column name from the displayColumns array:
private _materialPlan: IMaterialPlan = {};
@Input()
set MaterialPlan(prm: IMaterialPlan){
this._materialPlan = prm;
}
get MaterialPlan(): IMaterialPlan {
return this._materialPlan;
}
displayedColumns: string[] = [];
dataSource: MatTableDataSource<IMaterialPlanReceiptResult>;
@ViewChild(MatPaginator, { static: true }) paginator: MatPaginator;
@ViewChild(MatSort, { static: true }) sort: MatSort;
constructor(
) {
this.displayedColumns = [
'StockIntegrationCode',
'ReceiptName',
];
if(this._materialPlan.IncludePlannedParty == true){
this.isPublishedParty == true;
this.displayedColumns.push('PublishedParty');
}
}
