¿Cómo cambiar el texto del botón para los botones "Sí" y "No" en el cuadro de diálogo MessageBox.Show? (4)
Necesito cambiar los botones de control del cuadro de mensaje Yes a Continue y No a Close . ¿Cómo cambio el texto del botón?
Aquí está mi código:
DialogResult dlgResult = MessageBox.Show("Patterns have been logged successfully", "Logtool", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
¡No pensé que sería así de simple! vaya a este enlace: https://www.codeproject.com/Articles/18399/Localizing-System-MessageBox
Descargue la fuente. Tome el archivo MessageBoxManager.cs, agréguelo a su proyecto. Ahora solo regístrelo una vez en su código (por ejemplo, en el método Main () dentro de su archivo Program.cs) y funcionará cada vez que llame a MessageBox.Show ():
MessageBoxManager.OK = "Alright";
MessageBoxManager.Yes = "Yep!";
MessageBoxManager.No = "Nope";
MessageBoxManager.Register();

Esto puede no ser el más bonito, pero si no quieres usar el MessageBoxManager, (que es increíble):
public static DialogResult DialogBox(string title, string promptText, ref string value, string button1 = "OK", string button2 = "Cancel", string button3 = null)
{
Form form = new Form();
Label label = new Label();
TextBox textBox = new TextBox();
Button button_1 = new Button();
Button button_2 = new Button();
Button button_3 = new Button();
int buttonStartPos = 228; //Standard two button position
if (button3 != null)
buttonStartPos = 228 - 81;
else
{
button_3.Visible = false;
button_3.Enabled = false;
}
form.Text = title;
// Label
label.Text = promptText;
label.SetBounds(9, 20, 372, 13);
label.Font = new Font("Microsoft Tai Le", 10, FontStyle.Regular);
// TextBox
if (value == null)
{
}
else
{
textBox.Text = value;
textBox.SetBounds(12, 36, 372, 20);
textBox.Anchor = textBox.Anchor | AnchorStyles.Right;
}
button_1.Text = button1;
button_2.Text = button2;
button_3.Text = button3 ?? string.Empty;
button_1.DialogResult = DialogResult.OK;
button_2.DialogResult = DialogResult.Cancel;
button_3.DialogResult = DialogResult.Yes;
button_1.SetBounds(buttonStartPos, 72, 75, 23);
button_2.SetBounds(buttonStartPos + 81, 72, 75, 23);
button_3.SetBounds(buttonStartPos + (2 * 81), 72, 75, 23);
label.AutoSize = true;
button_1.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
button_2.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
button_3.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
form.ClientSize = new Size(396, 107);
form.Controls.AddRange(new Control[] { label, button_1, button_2 });
if (button3 != null)
form.Controls.Add(button_3);
if (value != null)
form.Controls.Add(textBox);
form.ClientSize = new Size(Math.Max(300, label.Right + 10), form.ClientSize.Height);
form.FormBorderStyle = FormBorderStyle.FixedDialog;
form.StartPosition = FormStartPosition.CenterScreen;
form.MinimizeBox = false;
form.MaximizeBox = false;
form.AcceptButton = button_1;

Simplemente agregue un nuevo formulario y agregue botones y una etiqueta. Proporcione el valor que se mostrará y el texto del botón, etc. en su constructor, y llámelo desde cualquier lugar que desee en el proyecto.
In project -> Add Component -> Windows Form and select a form
Agrega algunas etiquetas y botones.
Inicializa el valor en el constructor y llámalo desde cualquier lugar.
public class form1:System.Windows.Forms.Form
{
public form1()
{
}
public form1(string message,string buttonText1,string buttonText2)
{
lblMessage.Text = message;
button1.Text = buttonText1;
button2.Text = buttonText2;
}
}
// Write code for button1 and button2 ''s click event in order to call
// from any where in your current project.
// Calling
Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();
