LayoutView.CustomFieldValueStyle Event

Allows you to customize the appearance of field value regions in display mode.

Namespace:DevExpress.XtraGrid.Views.Layout
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.XtraGrid.Views.Layout.Events.LayoutViewFieldValueStyleEventArgs containing data related to this event.

Expanded Remarks

The CustomFieldValueStyle event fires for every card field when it's about to be displayed on-screen. You can handle this event to provide different appearances for field value regions in different cards. To customize the appearance settings, use the event's Appearance property.

While handling the CustomFieldValueStyle event you may need to identify the currently processed card. To do this, use the event's RowHandle parameter, which specifies the card's handle. To identify the currently processed card field, see the Column parameter.

The CustomFieldValueStyle event is not in effect when a field is edited. You need to handle the CustomFieldEditingValueStyle event to customize the appearance of field value regions in edit mode

Note

The control's events designed to change the appearance or rendering of control elements must not be used to update cell values or to modify the control's layout. Any inappropriate operation which causes a layout update, may break the normal control behavior.

Expanded Example

The following code shows how to dynamically customize the appearance of field values in a Layout View dependant on specific conditions.

In the example the CustomFieldValueStyle event is handled to customize the appearance of Description and CategoryName field values. Values of these fields are only painted in red in the cards that have the CategoryName field set to "Beverages".

The result is shown below:
