Ejemplos

En el ejemplo de código siguiente se controla el MaskInputRejected evento y se usa para ToolTip alertar al usuario si se intenta escribir datos después de que se hayan usado todas las posiciones de la máscara.

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

Comentarios

Puede usar la MaskFull propiedad dentro del MaskInputRejected controlador de eventos para determinar si se rechazó la entrada del usuario porque no hay entradas restantes en la máscara. Para determinar si solo se han especificado los elementos de entrada necesarios, use la MaskCompleted propiedad .
