RepositoryItemTextEdit.ShowNullValuePrompt Property

Gets or sets conditions under which this editor should display its null value text (see the NullValuePrompt (see NullValuePrompt) property).

Namespace:DevExpress.XtraEditors.Repository
Assembly:DevExpress.XtraEditors.v19.2.dll

Expanded Syntax

Property value

Type: ShowNullValuePromptOptions
Specifies conditions under which this editor should display its null value text.

Expanded Remarks

If you specify the NullValuePrompt (see NullValuePrompt) property, the editor displays this grayed-out text only when this editor is editable, not focused, and its EditValue is null. The ShowNullValuePrompt property allows you to expand the number of cases when the NullValuePrompt text is visible.

  • EmptyValue - the editor displays its NullValuePrompt text when the EditValue is null or empty (String.Empty).
  • EditorReadOnly - allows non-editable (read-only) editors with null value to display NullValuePrompt text.
  • EditorFocused - an editable editor with null value keeps showing its NullValuePrompt in both focused and unfocused states.
  • NullValue - none of the additional conditions are enabled.
  • Default - all three additional conditions are enabled.

The ShowNullValuePromptOptions is a flag enumeration, and the ShowNullValuePrompt property can accept more that one value.

Note that the editor keeps its NullValuePrompt text until a user starts editing (clicks a focused or double-clicks an unfocused editor).
