EXCEPTION: Form_MyForm.OnAfterFormLoad raised
Item - Invalid item  [66000-3]. Form Unique Id: 'MyForm_0',
Item Unique Id: '13'
can any one please help me

Answer 1

First , you have to get the event for the combo like this ...
            If pVal.Before_Action = True Then
                Select Case pVal.EventType
                    Case SAPbouiCOM.BoEventTypes.et_COMBO_SELECT ' on Combo Select
                         'your code here
                End Select
             End if
on the second case, you have to make sure of that the <b>form</b> UniqueID is correct
eItemNo = (EditText)(form.Items.Item("13").Specific);
