Remarks
If the AllowNullInput property is set to true, end-users can set the editor’s value to a null reference by pressing the CTRL+DEL or CTRL+0 key combinations. If the BaseEditSettings.NullValue property is specified, its value is assigned to the editor’s value. Otherwise, the editor’s value is set to null (Nothing in Visual Basic).
Note
The CTRL + 0 key combination does not work when using a French or German keyboard.
Note
By default, if an end-user clears the text displayed within the edit box, the BaseEdit.EditValue property is set to a null reference. The AllowNullInput property is not in effect in this instance.
