示例1: Form1_Load
// This example demonstrates the use of the ControlAdded and
// ControlRemoved events. This example assumes that two Button controls
// are added to the form and connected to the addControl_Click and
// removeControl_Click event-handler methods.
private void Form1_Load(object sender, System.EventArgs e)
{
// Connect the ControlRemoved and ControlAdded event handlers
// to the event-handler methods.
// ControlRemoved and ControlAdded are not available at design time.
this.ControlRemoved += new System.Windows.Forms.ControlEventHandler(this.Control_Removed);
this.ControlAdded += new System.Windows.Forms.ControlEventHandler(this.Control_Added);
}
private void Control_Added(object sender, System.Windows.Forms.ControlEventArgs e)
{
MessageBox.Show("The control named " + e.Control.Name + " has been added to the form.");
}
private void Control_Removed(object sender, System.Windows.Forms.ControlEventArgs e)
{
MessageBox.Show("The control named " + e.Control.Name + " has been removed from the form.");
}
// Click event handler for a Button control. Adds a TextBox to the form.
private void addControl_Click(object sender, System.EventArgs e)
{
// Create a new TextBox control and add it to the form.
TextBox textBox1 = new TextBox();
textBox1.Size = new Size(100,10);
textBox1.Location = new Point(10,10);
// Name the control in order to remove it later. The name must be specified
// if a control is added at run time.
textBox1.Name = "textBox1";
// Add the control to the form's control collection.
this.Controls.Add(textBox1);
}
// Click event handler for a Button control.
// Removes the previously added TextBox from the form.
private void removeControl_Click(object sender, System.EventArgs e)
{
// Loop through all controls in the form's control collection.
foreach (Control tempCtrl in this.Controls)
{
// Determine whether the control is textBox1,
// and if it is, remove it.
if (tempCtrl.Name == "textBox1")
{
this.Controls.Remove(tempCtrl);
}
}
