protected override ImeMode DefaultImeMode {get;}
Gets the default Input Method Editor (IME) mode supported by the control.
As implemented in the System.Windows.Forms.Control class, this property always returns the System.Windows.Forms.ImeMode.Inherit value. The Inherit value specifies that the IME mode is inherited from the parent control.
Notes to Inheritors:
When overriding the DefaultImeMode property in a derived class, use the base class's DefaultImeMode property to extend the base implementation; otherwise, you must provide all the implementation.
