Type: SystemBooleantrue if the server control contains solely literal content; otherwise false.
The following example checks whether the page that contains the server controls has posted back. If it has, it calls the IsLiteralContent method to determine whether the control contains just literal content, or is a parent control to other server controls. If it contains solely literal content, the UniqueID property of the LiteralControl that represents that content is written to the response.
' Override the OnLoad method to check if the
' page that uses this control has posted back.
' If so, check whether this controls contains
' only literal content, and if it does,
' it gets the UniqueID property and writes it
' to the page. Otherwise, it writes a message
' that the control contains more than literal content.
