Return Value

Type: System.Boolean
Always returns true.

The AllowWhitespaceLiterals method is used to determine whether white space literals are permitted in the content between the opening and closing tags of a control. When this method returns false, the white space literals are trimmed from the content before the content is processed by the page parser. When this method returns true, the white space literals not removed.

This method is called by the ASP.NET page framework during parsing and is not intended to be called directly in you code.

Notes to Inheritors

You can override this method in your derived class to indicate whether white space literals are permitted in your custom control.

// Create a class that does not allow white space generated by a control 
// to be created as a LiteralControl.
