DefaultValue ComboBox in Dynamics AX with X++

Beside modify metadata on form properties, as best practice we can use code like below to assign default value for combobox.

  • You can use this code in the form’s init method after super():
ComboBoxName.selection(ComboBoxName::DefaultValue);
  • If this is a table field we should you best practice overriding the initValue method in the table:
this.ComboBoxName = ComboBoxName::DefaultValue;
  • Override initValue in the form’s datasource only if it should be a specific behaviour in this form only.
