Control.Name Property

Gets or sets the name of the control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(false)]
public string Name { get; set; }

Property Value

Type: System.String
The name of the control. The default is an empty string ("").

The Name property can be used at run time to evaluate the object by name rather than type and programmatic name. Because the Name property returns a String type, it can be evaluated in case-style logic statements (Select statement in Visual Basic, switch statement in Visual C# and Visual C++).

The following code example displays the Name of a control in a MessageBox when the control is added or removed from a form.

// 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);
        }
    }
}
