Exemplos

O exemplo de código a seguir manipula o MaskInputRejected evento e usa um ToolTip para alertar o usuário se for feita uma tentativa de inserir dados depois que todas as posições na máscara tiverem sido usadas.

private void Form1_Load(object sender, EventArgs e)
{
    maskedTextBox1.Mask = "00/00/0000";

    maskedTextBox1.MaskInputRejected += new MaskInputRejectedEventHandler(maskedTextBox1_MaskInputRejected);
    maskedTextBox1.KeyDown += new KeyEventHandler(maskedTextBox1_KeyDown);
}

void maskedTextBox1_MaskInputRejected(object sender, MaskInputRejectedEventArgs e)
{
    if (maskedTextBox1.MaskFull)
    {
        toolTip1.ToolTipTitle = "Input Rejected - Too Much Data";
        toolTip1.Show("You cannot enter any more data into the date field. Delete some characters in order to insert more data.", maskedTextBox1, 0, -20, 5000);
    }
    else if (e.Position == maskedTextBox1.Mask.Length)
    {
        toolTip1.ToolTipTitle = "Input Rejected - End of Field";
        toolTip1.Show("You cannot add extra characters to the end of this date field.", maskedTextBox1, 0, -20, 5000);
    }
    else
    {
        toolTip1.ToolTipTitle = "Input Rejected";
        toolTip1.Show("You can only add numeric characters (0-9) into this date field.", maskedTextBox1, 0, -20, 5000);
    }
}

void maskedTextBox1_KeyDown(object sender, KeyEventArgs e)
{
    // The balloon tip is visible for five seconds; if the user types any data before it disappears, collapse it ourselves.
    toolTip1.Hide(maskedTextBox1);
}

Private Sub MaskedTextBox1_MaskInputRejected(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MaskInputRejectedEventArgs) Handles MaskedTextBox1.MaskInputRejected
    If (Me.MaskedTextBox1.MaskFull) Then
        ToolTip1.ToolTipTitle = "Input Rejected - Too Much Data"
        ToolTip1.Show("You cannot enter any more data into the date field. Delete some characters in order to insert more data.", Me.MaskedTextBox1, Me.MaskedTextBox1.Location.X, Me.MaskedTextBox1.Location.Y, 5000)
    ElseIf (e.Position = Me.MaskedTextBox1.Mask.Length) Then
        ToolTip1.ToolTipTitle = "Input Rejected - End of Field"
        ToolTip1.Show("You cannot add extra characters to the end of this date field.", Me.MaskedTextBox1, 0, -20, 5000)
    Else
        ToolTip1.ToolTipTitle = "Input Rejected"
        ToolTip1.Show("You can only add numeric characters (0-9) into this date field.", Me.MaskedTextBox1, 0, -20, 5000)
    End If
End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.ToolTip1.IsBalloon = True
    Me.MaskedTextBox1.Mask = "00/00/0000"
End Sub

Private Sub MaskedTextBox1_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles MaskedTextBox1.KeyDown
    ' The balloon tip is visible for five seconds; if the user types any data before it disappears, collapse it ourselves.
    Me.ToolTip1.Hide(Me.MaskedTextBox1)
End Sub

Comentários

Você pode usar a MaskFull propriedade dentro do MaskInputRejected manipulador de eventos para determinar se a entrada do usuário foi rejeitada porque não há entradas restantes na máscara. Para determinar se apenas os elementos de entrada necessários foram inseridos, use a MaskCompleted propriedade .
