How to: Create a Shortcut Menu and Attach it to a Control

This example programmatically creates a Windows Forms ContextMenu and associates it with a control.

Example

private void Form1_Load(object sender, System.EventArgs e)

{

System.Windows.Forms.ContextMenu contextMenu1;

contextMenu1 = new System.Windows.Forms.ContextMenu();

System.Windows.Forms.MenuItem menuItem1;

menuItem1 = new System.Windows.Forms.MenuItem();

System.Windows.Forms.MenuItem menuItem2;

menuItem2 = new System.Windows.Forms.MenuItem();

System.Windows.Forms.MenuItem menuItem3;

menuItem3 = new System.Windows.Forms.MenuItem();

contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {menuItem1, menuItem2, menuItem3});

menuItem1.Index = 0;

menuItem1.Text = "MenuItem1";

menuItem2.Index = 1;

menuItem2.Text = "MenuItem2";

menuItem3.Index = 2;

menuItem3.Text = "MenuItem3";

textBox1.ContextMenu = contextMenu1;

}

Compiling the Code

This example requires:

· A Windows Form named Form1 and a TextBox control named textBox1. Click the form and paste the code into the Load event handler. When you execute the application and right-click textBox1, a shortcut menu displays three commands.

How to: Add Windows Forms Controls at Run Time

This example creates a new instance of a Windows Forms TextBox control at runtime.

Example

private void Form1_Load(object sender, System.EventArgs e)

{

TextBox MyTextBox = new System.Windows.Forms.TextBox();

MyTextBox.Location = new System.Drawing.Point(64, 40);

MyTextBox.Name = "MyTextBox";

MyTextBox.Size = new System.Drawing.Size(88, 21);

MyTextBox.TabIndex = 0;

MyTextBox.Text = "MyTextBox";

Controls.Add(MyTextBox);

// Adding the DoubleClick event.

MyTextBox.DoubleClick += new EventHandler( MyTextBox_DoubleClick );

}

private void MyTextBox_DoubleClick(object sender, System.EventArgs e)

{

MessageBox.Show("MyTextBox doubleClick event.");

}

Compiling the Code

· The example requires a reference to the System.Windows.Forms namespace.
