Event triggered when changing a Document header field (eg change the exchange).

In version 9, at the header level, you only have 2 events in VBA:

EditorVendas_TipoDocumentoIdentificado
EditorVendas_ClienteIdentificado 

In version 10 this will already be different and there will be other possibilities.

There is no native event that allows you to invoke methods by changing a value in the header, except for, as well as @ManuelQuelhas, TipoDocumentoIdentificado and ClienteIdentificado . However, there is the TeclaPressionada method, which allows, at any time, with the press of a button to evoke code in VBA. Having said this, perhaps the ideal would be to implement a method to recall from a key or key combination ( SHIFT or CTRL + key).

Example:

Private Sub EditorVendas_TeclaPressionada(KeyCode As Integer, Shift As Integer)
Dim objLinhaVenda As GcpBELinhaDocumentoVenda

    On Error GoTo Erro

    If KeyCode = vbKeyF3 And Me.DocumentoVenda.Linhas.NumItens > 0 Then
        For Each objLinhaVenda In Me.DocumentoVenda.Linhas
            'o teu código aqui
            '...
        Next
    End If

    Set objLinhaVenda = Nothing

    Exit Sub
