Hide an element from the combo box

Let say you you two forms where this enum is reflected, namely Form1 and Form2. In order to hide an element from Form1 and continue showing it on Form2 go to form design and then access that combo box control. Override the enter() method of that combo box and write this line to delete the element from it.

combobox:enter()
{
super();
this.delete(enum2str(BaseEnum::Element4));
}
