The HTML fails to update after changes are made to the model value

In my current project, I am working on a feature that requires a single component to display data from different tables based on the menu item clicked.

Using Observables, I have implemented the same component for both the Units and Colors modules.

1) When I click on Units in the first screenshot, it successfully displays the correct data in the grid. https://i.sstatic.net/EOMRD.png

2) However, when I click on Colors in the second screenshot, the grid data should update accordingly. Unfortunately, it is not updating or triggering any controller or API calls to the server. https://i.sstatic.net/zqEtD.png

I have already tried implementing change detection using ChangeDetectorRef and ngDoCheck, but without success.

Here's a snippet of my code for the component:

export class ListMasterMainComponent implements OnInit
{
    // Component properties and methods...
}

For handling Menu Item Click:

onClickMainMasters(message)
{
    // Logic for changing message and URL based on menu item clicked...
}

Any assistance would be greatly appreciated. Thank you.

Answer №1

It appears that you are repeatedly navigating to the same url/component /listmaster. However, if the activeRoute remains unchanged, the component will not reload. If the correct data display relies on your fechtData() function being called in the ngOnInit of your ListMasterMainComponent, you must ensure that this component is reinitialized or call fetchData() from another location.
