Executing function in component via template

Within the template section

<tr *ngFor='let activity of pagedWorkflowActivities' [style.background-color]="setBackgroundColor(activity)">

In the component section

setBackgroundColor(activity: WorkflowActivity) {
    return 'red';
}

The code above was implemented in the same component where all other related events for the template are located. I believe this is the appropriate place for it. However, I am encountering an error message in the developer tools:

self.parent.context.setBackgroundColor is not a function

Answer №1

After numerous attempts to solve the issue, I finally resorted to resetting IIS (since I am using Asp.Net) and rebuilding the solution - surprisingly, it worked like a charm. Just a few days ago, I encountered the same problem, which eventually disappeared on its own the following day. It could've been a caching issue, but nonetheless quite frustrating.

Edit Another method you can try is running the command ipconfig /flushdns to prevent unnecessary solution rebuilds.

Edit For testing purposes, I tried using IE, Chrome, and FF, and interestingly found that FF reflected changes quicker than the others.
