OptionsColumnFilter.ShowBlanksFilterItems Property

Gets or sets whether the column's Filter Dropdown (when presented as a Regular List or Checked List) displays the "(Blanks)" and "(Non Blanks)" filter items.

Namespace:DevExpress.XtraGrid.Columns
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Property value

Type: DefaultBoolean
A DevExpress.Utils.DefaultBoolean value that specifies whether the column's Filter Dropdown displays the "(Blanks)" and "(Non Blanks)" filter items.
The default is DefaultBoolean.Default.

Expanded Remarks

The paint style of a column's Filter Dropdown is specified by the FilterPopupMode property. When the Filter Dropdown is painted as a Regular List or Checked List, it may contain the "(Blanks)" and "(Non Blanks)" items used to filter records that contain Null (DBNull) values and empty strings.

If the ShowBlanksFilterItems property is set to Default, the "(Blanks)" and "(Non Blanks)" items are present in the Filter Dropdown if the View's data source contains records with Null or DBNull in the current column. If the ShowBlanksFilterItems property is set to True, the "(Blanks)" and "(Non Blanks)" filter items are always available in the Filter Dropdown. Set the ShowBlanksFilterItems property to False to forcibly hide the "(Blanks)" and "(Non Blanks)" filter items.

Note

For the Filter Dropdown painted as a Checked List, the "(Non Blanks)" item is not supported. The Checked Filter Dropdown supports only the "(Blanks)" item.
