Form.ControlCollection Class

Assembly: System.Windows.Forms (in

public class ControlCollection : ControlCollection

Not applicable.

This class represents the collection of controls contained within a form. You can use the Add method to add a control to the form and the Remove method to remove the control from the form. The control collection represented by this class cannot be created without binding it to a specific form. As a result, you cannot create multiple instances of this control collection and interchange them with an active form to provide different control layouts.

The following code example adds a TextBox and Label control to the control collection of a form. The example requires that a form has been created and named Form1.

public void AddMyControls()
    TextBox textBox1 = new TextBox();
    Label label1 = new Label();
    // Initialize the controls and their bounds.
    label1.Text = "First Name";
    label1.Location = new Point(48,48);
    label1.Size = new Size (104, 16);
    textBox1.Text = "";
    textBox1.Location = new Point(48, 64);
    textBox1.Size = new Size(104,16);
    // Add the TextBox control to the form's control collection.
    // Add the Label control to the form's control collection.
