Property Paths

You can access the BaseEditSettings.AllowNullInput property from the following objects:

Object Type	Path to AllowNullInput
BarEditItem	.EditSettings.AllowNullInput
ColumnBase	.ActualEditSettings.AllowNullInput
ColumnBase	.EditSettings.AllowNullInput
GridColumn	.ActualEditSettings.AllowNullInput
GridColumn	.EditSettings.AllowNullInput
TreeListColumn	.ActualEditSettings.AllowNullInput

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

CTRL + 0 key combination does not work when using a French 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.
