CardView.CustomDrawCardField Event

Enables you to custom paint card fields.

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

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type RowCellCustomDrawEventArgs containing data related to this event.

The following RowCellCustomDrawEventArgs properties provide information specific to this event.
Property Description
Appearance Gets the painted element's appearance settings.
Bounds Returns a value specifying limits for the drawing area.
Cache Gets an object which specifies the storage for the most often used pens, fonts and brushes.
Cell Provides information on the painted cell.
CellValue Gets the painted value or display text (depending on the event).
Column Gets the column whose element is being painted.
DisplayText Gets or sets the painted element's display text.
Graphics Gets an object used to paint.
Handled Gets or sets a value specifying whether an event was handled and that the default element painting is therefore not required.
RowHandle Gets the handle of a painted element's row.

Expanded Remarks

Card fields consist of captions and value cells. Therefore, the event's CustomDrawEventArgs.Bounds parameter specifies the rectangle bounding both these elements. If you need to custom paint field captions and value cells separately, handle the CustomDrawCardFieldCaption and CustomDrawCardFieldValue events instead.

If you set the event's CustomDrawEventArgs.Handled parameter to true, the CustomDrawCardFieldCaption and CustomDrawCardFieldValue events will not fire.

See the Custom Painting Basics and Custom Painting Scenarios topics for information on using custom draw events.
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 sample code below handles the CustomDrawCardField event to custom paint fields whose GridColumn.FieldName properties are not set. Such fields are considered header fields, which precede regular data fields.

A header field's caption is painted centered. The field value is hidden.
