What is a LiteralControl? I was reading about LiteralContols but I am not sure why they are used. I used this code to list the controls in a page and - I have a page which has a label and a button. When I use this 

foreach (Control control in Page.Controls)
{
    Response.Write(control.GetType().ToString() + " - <b> " + control.ID + "</b><br />");    

    if (control is LiteralControl)
    {
        Response.Write("Textt :" + ((LiteralControl)control).Text.ToString() + " - " + 
            Server.HtmlEncode(((LiteralControl)control).Text + "<br />") ); 
    }
}

I find that there are actually LiteralControls that are generated and listed before and after every control I have added to my page. Literal Controls also have only text property.

I am still not sure why LiteralControls are needed and used? Why are LiteralControls used? Why do controls that I add to my page have one LiteralControl placed before and after? And why do they have only Text Property?

A LiteralControl is used to inject HTML into your page at runtime.
