Comment : créer une bordure autour d'un contrôle Windows Form à l'aide du remplissage
L’exemple de code suivant montre comment créer une bordure ou un contour autour d’un contrôle RichTextBox. L’exemple définit la valeur de la propriété Padding d’un contrôle Panel à 5 et définit la propriété Dock d’un contrôle RichTextBox enfant à Fill. Le BackColor du contrôle Panel est défini sur Blue, ce qui crée une bordure bleue autour du contrôle RichTextBox.
Exemple
using System;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;
namespace MarginAndPadding
{
public class Form1 : Form
{
private Panel panel1;
private RichTextBox richTextBox1;
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
// This code example demonstrates using the Padding property to
// create a border around a RichTextBox control.
public Form1()
{
InitializeComponent();
this.panel1.BackColor = System.Drawing.Color.Blue;
this.panel1.Padding = new System.Windows.Forms.Padding(5);
this.panel1.Dock = System.Windows.Forms.DockStyle.Fill;
this.richTextBox1.BorderStyle = System.Windows.Forms.BorderStyle.None;
this.richTextBox1.Dock = System.Windows.Forms.DockStyle.Fill;
}
