AX2012 Custom Lookup on a Dialog
Today I struggled with a custom lookup on a dialog in Microsoft Dynamics AX 2012. To prevent this from happening to me again, and maybe to help you out too, I will share the solution with you here.
The following code will utilize a class which extends the AX2012 RunBase class, with a simple dialog and a custom lookup on an added field.
Here the class declaration, don’t forget to extend RunBase.
Nothing special here either, just get a new instance from your class, to be able to run it later on.
This is where the fun starts. You simply want to get the control from your field, then you call the registerOverrideMethod(…) and as parameter you provide your class name (in this case, the class we are actually writing here) and the method name (this does not have to be lookup!).
The custom lookup
In the last step we will just set up a “normal” (don’t forget the FormStringControl!) lookup method.
