Here is a helpful guide on passing parameters to Angular 2 directives.
<p [gridGroup]="gridGroup"></p>
My goal is to have the parameter as optional so that it doesn't have to be included in every class referencing the html source.
Currently, I must include gridGroup in each class where this html source is referenced.
I attempted
<p [gridGroup?]="gridGroup"></p>
and
<p [gridGroup]="gridGroup?"></p>
However, both attempts resulted in compile errors.
Ensure the gridGroup property in your component is initialized to a default value. This will prevent errors if the property is not defined in the parent component.
Here is an example of how it can be achieved
@Input defineGridGroup(newValue: any) {
this._gridGroup= newValue;
performAction(newValue);
}
