Trick: Instantiating any control in a Control Add-in
My two last blog posts tackled two aspects of working with control add-ins: making any property or method accessible to C/AL, and making any event accessible to C/AL The first was a simple trick, the second was a bit more complex. Together, these two tricks enable you to easily interact with whatever Windows Forms control the add-in shows: you can access any of inner control’s members – properties, methods, or events. At this stage, there is a very simple, but robust framework in place, which lets you publish any kind of control and make it fully available to C/AL. Cool.
But, couldn’t we make it a bit cooler? How about being able to instantiate any control, and having C/AL decide which control to instantiate, instead of hardcoding it in the C# code?
Yes, we can do this.
