ControlBuilder.InDesigner Property

Returns whether the ControlBuilder is running in the designer.

[Visual Basic]
Protected ReadOnly Property InDesigner As Boolean
[C#]
protected bool InDesigner {get;}
[C++]
protected: __property bool get_InDesigner();
[JScript]
protected function get InDesigner() : Boolean;

Property Value

true if the ControlBuilder is running in the designer; otherwise, false.

Example

[Visual Basic] The following example uses the InDesigner property when the NeedsTagInnerText method is called. When a control has this builder attached to it, the NeedsTagInnerText determines whether the control is being accessed at design-time through a designer. The NeedsTagInnerText method call returns the value of the InDesigner property, and then the SetTagInnerText method is called. If the InDesigner property is set to false, an Exception is thrown. Otherwise, the inner text of the control is returned on the SetTagInnerText call.

[Visual Basic] 
Public Class MyControlControlBuilder
  Inherits ControlBuilder
    
    Private _innerText As String
    
    Overrides Public Function NeedsTagInnerText() As Boolean
      Return InDesigner
    End Function
    
    Overrides Public Sub SetTagInnerText(ByVal text As String)        
       If InDesigner = False
         Throw New System.Exception("The control is not in design mode.")
       Else
         _innerText = text
       End If
    End Sub
    
End Class
