Customized Lookup In Reference Group Control

This blog describes how to implement customized lookups in reference group control in Dynamics AX form.

Steps

1. Add a reference group control on the form.
2. Override the lookup method of the control and add the following lines of code 
   
   
   
3. In the lookup form, override the closeSelect() method of the form and comment the super of the method.
4. Two different situations may occur when selecting a record in the lookup form:
1. If the reference group control’s reference field is contained in the lookup form’s parent data source, then pass that datasource buffer as a parameter to the closeSelectRecord() method.
   
   
   
2. Otherwise, if the reference field is not contained in the parent data source, call a method on the calling form from the lookup form. For this, create a method on the calling form that accepts the buffer from the lookup form. In this method assign the passed record to the reference field.
