Hi.
I have created a custom yii\grid\DataColumn used to display customized data. I use this both with standard and Kartik’s gridview, but the latter uses more methods and functions, so if I’m using it the constructor fails… I either use two classes for the two DataColumns, or can I use Dependency Injection? This means I should create my DataColumn as a standard object, and instantiate the parent DataColumn class from config parameters. I tried implementing something like this, a stub is below, but it didn’t work as expected. The DataColumn class didn’t have access to $this->view.
I’m going to implement this a formatter, but for learning purposes, how can this be accomplished using D-I? thanks
