here is my html file
<ngb-panel *ngFor="let panel of panels" id="" [title]="panel.Name">
<label class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" [name]="panel.Id + '-' + panel.Moniker" [ngModel]="checkAllTestsSelected(panel)"
(ngModelChange)="onPanelCheckboxUpdate($event, panel)" [id]="panel.Id + '-' + panel.Moniker">
<span class="custom-control-indicator"></span>
</label>
</ng-template>
<ng-template ngbPanelContent>
<div class="individual-panel" *ngFor="let test of panel.Tests">
<span class="text-dimmed"></span>
<span *ngIf="panel.Name.includes('ENA') || panel.Name.includes('Celiac')">
<label class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" [name]="test.Id + '-' + test.Code"
[ngModel]="testSelectionSession.SelectedPanelIds.indexOf(panel.Id) > -1 || testSelectionSession.SelectedPanelIds.indexOf(test.AssociatedPanel?.Id) > -1"
(ngModelChange)="onTestCheckboxUpdate($event, test, panel)"
[id]="test.Id + '-' + test.Code">
<span class="custom-control-indicator"></span>
</label>
</span>
</div>

checkAllTestsSelected(panel: TestOrderPanel) {
// get all individual test panels
let individualTestPanelIds = panel.Tests.reduce((acc, test) => {
if (test.AssociatedPanel) {
acc.push(test.AssociatedPanel.Id);
}
return acc;
}, []);
// check if all individual test panels are selected
let allIndividualTestsSelected = individualTestPanelIds.reduce(
(acc: boolean, panelId: number) =>
acc && this.panelIds.indexOf(panelId) > -1,
individualTestPanelIds.length > 0 &&

this.panelIds.push(panel.Id);
this.selectedPanels.push(panel);
this.updateSession();
}
return this.panelIds.indexOf(panel.Id) > -1;
}
onPanelCheckboxUpdate($event: boolean, panel: TestOrderPanel) {
let testPanelIds = panel.Tests.reduce((acc, test) => {
if (test.AssociatedPanel) {
acc.push(test.AssociatedPanel.Id);
}
return acc;
}, []);
// Wipe any duplicates
this.panelIds = this.panelIds.filter(
panelId => panel.Id !== panelId && testPanelIds.indexOf(panelId) === -1
);
this.selectedPanels = this.selectedPanels.filter(
selectedPanel =>
panel.Id !== selectedPanel.Id &&
testPanelIds.indexOf(selectedPanel.Id) === -1
);
if ($event) {
this.panelIds.push(panel.Id);
this.selectedPanels.push(panel);
}
this.updateSession();
}
onTestCheckboxUpdate($event: boolean,
test: TestOrderPanelTest,
panel: TestOrderPanel,
index) {
let testPanelIds = panel.Tests.reduce((acc, test) => {
if (test.AssociatedPanel) {
acc.push(test.AssociatedPanel.Id);
}
return acc;
}, []);
let associatedTestPanels =
this.testSelectionSession.IndividualTestPanelsForAll.filter(
testPanel => testPanelIds.indexOf(testPanel.Id) > -1
);
// If the panel is selected and a test within the panel is deselected,
// remove the panel and back all of the individual tests
if (this.panelIds.indexOf(panel.Id) > -1 && !$event) {
this.selectedPanels = this.selectedPanels.filter(
e => e.Tests.splice(index, 1)
);
}
let clickedTestPanel = associatedTestPanels.find(
testPanel => (test.AssociatedPanel ? test.AssociatedPanel.Id : -1) ===
testPanel.Id
);
if (clickedTestPanel) {
// Wipe any duplicates
this.panelIds = this.panelIds.filter(
panelId => clickedTestPanel.Id !== panelId
);
this.selectedPanels = this.selectedPanels.filter(
panel => clickedTestPanel.Id !== panel.Id
);
// Add individual panel if checkbox selected
if ($event) {
this.panelIds = this.panelIds.concat(clickedTestPanel.Id);
this.selectedPanels = this.selectedPanels.concat(clickedTestPanel);
}
}
this.updateSession();
}
this.panelIds includes IDs of panels and this.selectedPanels includes whole panel array which is selected.
i have created a stackblitz too
my code is doing something like that stackblitz.com/edit/angular-bsszc9
and here is example of how my page will look like stackblitz
how can i solve this problem? thanks
