MaskedTextBox.AcceptsTabChanged Event
.NET Framework 4
Occurs when the value of the AcceptsTab property has changed. This event is not raised by MaskedTextBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The AcceptsTabChanged event is inherited from the base TextBoxBase class. However, because the MaskedTextBox control does not support multiline configuration, this event is not supported.
