Difference between Label
Control and Literal Control
·
The main difference is, you
can apply style to a Label control where as you can not apply styles in a
literal control.
·
Label control renders as span
tag in a webpage while Literal Control only shows the text without any tag
associated to it.
·
Literal control does not
maintain its viewstate.
ASP.NET Literal itself is a
class which is present under System.Web.UI namespace.
Literal Mode property:
i.
PassThrough: If you
set this property, then the content will not be modified and rendered as is. For
eg., if string contains <hr> tag then its dependent on your browser, of how it
handles <hr> tag.
ii.
Encode: If you set
this property then content will be encoded and sent to browser for e.g., if your
string contains <hr> tag, then your string will be converted to <Hr> and
sent to browser.
iii.
Transform: If you set
Mode property to Transform then the string render depends upon the type of the
markup.
Code:
<asp:Literal
ID="Literal1"
runat="server"></asp:Literal>
