Remarks

Use the ShowHeaderFilterBlankItems property to control whether specific ‘Blanks’ and ‘Non blanks’ filter items should be displayed in the header filter popup window. If enabled, these filter items allow end-users to filter data by blank and non blank values. You can define custom captions for these filter items by using the ASPxGridTextSettingsBase.HeaderFilterShowBlanks and ASPxGridTextSettingsBase.HeaderFilterShowNonBlanks properties.

Note

The ShowHeaderFilterBlankItems property is not in effect (the ‘Blanks’ and ‘Non blanks’ are not displayed) if the GridDataColumnSettings.HeaderFilterMode property is set to CheckedList.
