Difference between a Label and Literal control in asp.net

Lable
System.Object

  System.Web.UI.Control
    System.Web.UI.WebControls.WebControl
      System.Web.UI.WebControls.Label

<asp:Label ID="lblFirstName" runat="server" CssClass="myCssClass"Text="First Name" />

Literal

System.Object
  System.Web.UI.Control
    System.Web.UI.WebControls.Literal 

<asp:Literal id="litFirstName" runat="server" Text="First Name" />

Now, bind your controls with some text :-

lblFirstName.Text = "text";

litFirstName.Text = "text";

Output will be show html of page run-time : 

<span id="lblFirstName">text</span>

<br />

text

------------------------------------------------------------------------------

we see that the label text is wrapped around a span tag and the literal text is simply putting a text in it. 

label control has much more properties than the literal control, so choose wisely.
