Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


By default, every user control on a page is associated with a default UserControlControlBuilder class. This class adds a child control to the Controls property for every nested user control that it encounters within the custom control tags. Additionally, it creates literal controls for the text located between nested control tags. You can create custom user control builder funtionality by extending this class.


[Visual Basic] The following example creates a custom UserControlControlBuilder class that overrides the AllowWhitespaceLiterals method that this class inherits from the ControlBuilder class. When applied to a UserControl class, white spaces found in the user control are ignored.

[Visual Basic] 
' This is a Custom builder for user controls.
' It does not allow white space to be returned
' as instances of the LiteralControl class.
Public Class CustomUCBuilder
   Inherits UserControlControlBuilder
    Public Sub New()
    End Sub
  ' UserControlControlBuilder inherits this from
  ' ControlBuilder, but uses the base functionality
  ' of the method. You can override it to 
  ' create the custom behavior you want.  
  Public Overrides Function AllowWhitespaceLiterals() As Boolean
     Return False
  End Function
End Class
