I have an application that has one graph component and my idea is that when use clicks on a graph the correct filtering will occur on the other component which is an primeng data table
for that end i've created an event and i can capture the event on the table component
then i tried two approaches to filter the table correctly
1.using ngModel, setting the value based on the event - not working
<p-column field="result" [filter]="true" [style]="{'overflow':'visible'}" filterMatchMode="equals">
<ng-template let-col let-compliance="rowData" let-ri="rowIndex" pTemplate="body">
<span [ngClass]="{green: compliance.result=='SUCCESS', red: compliance.result=='FAILURE',
orange: compliance.result=='EXCLUDED', grey: compliance.result=='UNCHECKED'}">{{compliance.result}}</span>
</ng-template>
<ng-template pTemplate="filter" let-col>
<p-dropdown [options]="stationResults" [style]="{'width':'100%'}" appendTo="body"
(onChange)="dt.filter($event.value,col.field,col.filterMatchMode)" styleClass="ui-column-filter" [(ngModel)]="selectedResult"></p-dropdown>
</ng-template>
</p-column>
table is not being filtered
later i tried a second approach
2.add filters property to the datatable
this.stationService.upDownGraphEvent.subscribe(upDownEvent => {
this.dt.filter(upDownEvent, 'result', 'equals');
this.selectedResult = upDownEvent;
});
in that case nothing happens
is there a function i need to call on the dt to force it to recheck its filters?
UPDATE ******
I've tried the following code but without success
this.dt.filter(upDownEvent, 'result', 'equals');
this.dt._filter();
this.dt.updateDataToRender(this.dt.filteredValue);
You can use the globalFilter property binding as below
<input #filterText type="text" placeholder="Search text...">
<p-dataTable [value]="compliance" [globalFilter]="filterText">
this.alertService.alertSwitchGraphEvent.subscribe(switchNameEvent => {
if(this.dt.dataToRender){
this.dt.filter(switchNameEvent, 'switchName', 'equals');
}
});
I've created an external event that emitted, on the datatable component i subscribe to it and then i call the dt.filter
