RepositoryItemDateEdit.ShowClear Property

Gets or sets a value indicating whether the dropdown calendar contains a Clear button.

Namespace:DevExpress.XtraEditors.Repository
Assembly:DevExpress.XtraEditors.v17.2.dll

Expanded Syntax

Property value

Type: Boolean
true, if the dropdown calendar contains a Clear button; otherwise, false.
The default is true.

Expanded Remarks

The ShowClear property specifies the visibility of the Clear button in the dropdown calendar in the CalendarView.Classic and CalendarView.Vista modes. The Clear button allows end-users to clear the currently selected date. Clicking the button assigns the NullDate property value to the edit value and closes the dropdown. By default, NullDate is set to null. The NullDate property can be set to any date value.

The ShowClear and RepositoryItemTextEdit.AllowNullInput properties are synchronized. The AllowNullInput property determines whether an end-user can assign a null reference to the edit value by pressing the CTRL+0 and CTRL+DEL shortcuts. This functionality is enabled for a date editor if this property is set to Default or True.

Setting the ShowClear property to true sets the AllowNullInput property to Default automatically and vice versa. Setting the ShowClear property to false sets the AllowNullInput property to False and vice versa.
Note

The ShowClear property, and so the Clear button are not supported when the CalendarView property is set to TouchUI.
