catching COMBO BOX item changed in VALIDATE event


Hi expert,

I need to catch the item changed event for a combo box.

below the code:

<B1Listener(BoEventTypes.et_VALIDATE, False)> _

Public Overridable Sub OnAfterValidate(ByVal pVal As ItemEvent)

Dim form As Form = B1Connections.theAppl.Forms().Item(pVal.FormUID)

Dim mt As Matrix = Form.Items.Item("Matrix_0").Specific

if (pVal.ColUID.Equals("TipoList") And pVal.ItemChanged) Then


end if

but pVal.ItemChanged is always equal to false even if I change the value selected in combo box.

can anyone help me?

Thanks in advance.

Best regards
