Gets or sets a value indicating whether the text property is being changed internally by its parent class.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The property acts as a flag for the UpDownBase class. This property is used by derived classes to indicate when the class is changing the current Text property internally. If this property is set to false, the control requires that the user is changing the Text property and will set the UserEdit property to true.
