title: Where are controls stored after they had been created on run time?
body: <p>I'm newer in .NET programming.</p>
  
  <p>I need to create a multiple TextBoxies at run time.</p>
  
  <p>I have the following VB NET code:</p>
  
  <pre><code>    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  
     Dim textbox1 As New TextBox
     static Dim shiftDown As Integer
     static Dim counter As Integer
  
      counter += 1
      shiftDown = shiftDown + 30
      textbox1.Name = "Textbox" + counter.ToString()
      textbox1.Size = New Size(170, 10)
      textbox1.Location = New Point(10, 32 + shiftDown)
      textbox1.Visible = True
      GroupBox1.Controls.Add(textbox1)
  
  End Sub
  </code></pre>
  
  <p>This code example creates on Form multiple Text Boxies at run time after clicking the Button1.</p>
  
  <p>My question where the created Text Boxies is stored after the Button was clicked? </p>
