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
