What ways can you dynamically create controls in C#?

This was objects at first but it would have been more precise to say controls. My terminology was messed up. Thanks Joel.

Edit{
Controls that are created during runtime. And are able to be accessed and edited by the program.
Does this help?
}

I like the idea of Dynamic creation and was wondering what ways there were to do this.

Please only one per answer, I would like to see how people rank them.

eg

private Label _lblCLastName = new Label(); 
private static List<ChildrenPanel> _ListCP = new List<ChildrenPanel>(); 

public void CreatePanel(Panel Container) 
{ 
    // Created Controls
    #region Controls 
    _pnlStudent.Controls.Add(_lblCLastName); 
    //  
    // lblCLastName 
    //  
    _lblCLastName.AutoSize = true; 
    _lblCLastName.Location = new System.Drawing.Point(6, 32); 
    _lblCLastName.Name = "lblCLastName"; 
    _lblCLastName.Size = new System.Drawing.Size(58, 13); 
    _lblCLastName.TabIndex = 10; 
    _lblCLastName.Text = "Last Name"; 

    // Adds controls to selected forms panel 
    Container.Controls.Add(_pnlStudent); 
    // Creates a list of created panels inside the class 
    // So I can access user input 
    ListCP.Add(this); 

}

This is a code snippet from something that is close to what I’m talking about. I made another post but didn’t quite post the question right. I will be deleting it but atm it is still viewable.

If there are still problems please be constructive I don’t mind negitive input as long as it’s helpful.

Edit:
I was able to get some answers I was looking for. Thank you to everyone who replied. I will close this when I am able too. If someone else can close it that would be appreciated.

    Creating GUI objects dynamically can be extremely useful, however, it can also be a nightmare for maintenance.

    A good rule of thumb is to limit the amount of GUI object you dynamically create.

    One situation where you may actually want to use a dynamically created GUI object is when you don’t know the amount or count of objects you need. For example, one label for each row in a result set (even then you may consider a DataGrid or GridView type object).

    This works for both WinForms and ASP.NET. Just be sure to document your code correctly.

    My advice would be to stick with the Visual Designer for simpler forms and only create and add objects dynamically when it’s absolutely necessary.

    (FWIW, the code snippet you posted could probably be simplified and/or refactored as it seems to be going in the wrong direction.)
