Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el AppendText método y la TextLength propiedad para copiar texto de uno TextBox a otro. En este ejemplo se requiere que se hayan agregado dos TextBox controles denominados y textBox2textBox1 , a un formulario y que textBox1 tenga texto asignado a su Text propiedad .

void AppendTextBox1Text()
{
   // Determine if text is selected in textBox1.
   if ( textBox1->SelectionLength == 0 )

   // No selection made, return.
   return;

   // Determine if the text being appended to textBox2 exceeds the MaxLength property.
   if ( (textBox1->SelectedText->Length + textBox2->TextLength) > textBox2->MaxLength )
         MessageBox::Show( "The text to paste in is larger than the maximum number of characters allowed" ); // Append the text from textBox1 into textBox2.
   else
         textBox2->AppendText( textBox1->SelectedText );
}

private void AppendTextBox1Text()
{
   // Determine if text is selected in textBox1.
   if(textBox1.SelectionLength == 0)
      // No selection made, return.
      return;
   
   // Determine if the text being appended to textBox2 exceeds the MaxLength property.
   if((textBox1.SelectedText.Length + textBox2.TextLength) > textBox2.MaxLength)
      MessageBox.Show("The text to paste in is larger than the maximum number of characters allowed");
   else
      // Append the text from textBox1 into textBox2.
      textBox2.AppendText(textBox1.SelectedText);
}

Private Sub AppendTextBox1Text()
   ' Determine if text is selected in textBox1.
   If textBox1.SelectionLength = 0 Then
      ' No selection made, return.
      Return
   End If
   ' Determine if the text being appended to textBox2 exceeds the MaxLength property.
   If textBox1.SelectedText.Length + textBox2.TextLength > textBox2.MaxLength Then
      MessageBox.Show("The text to paste in is larger than the maximum number of characters allowed")
      ' Append the text from textBox1 into textBox2.
   Else
      textBox2.AppendText(textBox1.SelectedText)
   End If
End Sub

Comentarios

Puede usar este método para agregar texto al texto existente en el control en lugar de usar el operador de concatenación (+) para concatenar texto en la Text propiedad .
