DateEdit.DrawItem Event

Provides the ability to custom paint day cells in the dropdown calendar.

Namespace:DevExpress.XtraEditors
Assembly:DevExpress.XtraEditors.v17.2.dll

Expanded Syntax

Expanded Event Data

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

The following CustomDrawDayNumberCellEventArgs properties provide information specific to this event.
Property Description
BackgroundElementInfo Gets or sets the skin element that is used to paint the background of the currently processed cell.
Bounds Gets the painted element's bounding rectangle.
Cache Gets an object that specifies the storage for the most used pens, fonts and brushes.
ContentBounds Gets the bounds of the cell's content (text).
Date Gets the painted cell's value.
Disabled Gets whether the painted cell is disabled.
Graphics Gets an object used to paint.
Handled Gets or sets a value specifying whether default painting is prohibited.
Highlighted Gets whether the currently processed cell is under the mouse cursor.
Holiday Gets whether the painted cell corresponds to Saturday or Sunday.
Inactive Gets whether the painted cell belongs to the previous or next month.
IsPressed Gets whether the cell is currently pressed.
IsSpecial Gets whether the cell corresponds to a "special" date.
Selected Gets a value indicating whether the processed day number cell is selected.
State Gets the current cell's state.
Style Gets the painted date cell's appearance settings.
Today Gets whether the painted cell corresponds to Today's date.
View Gets or sets the current View of data in the dropdown window.
ViewInfo Contains information used for painting the current cell.

Expanded Remarks

The DrawItem event fires when a day cell in the dropdown calendar is about to be painted. Handle this event, for instance, if you wish to custom paint particular dates, e.g. by highlighting them.

The event parameter's properties provide the information which is needed to paint a day cell. You must set the CustomDrawDayNumberCellEventArgs.Handled property to true to override the default painting.

The editor's DrawItem event is equivalent to the RepositoryItemDateEdit.DrawItem event available via the Properties object.

Note

You can use drawing methods provided by the e.Graphics object to paint custom information via the DrawItem event. Alternatively, you can use drawing methods provided by the e.Cache or e.Style objects. If using the methods provided by the e.Cache or e.Style objects, ensure that the static DevExpress.Utils.Paint.XPaint.ForceGDIPlusPaint method is called on the application startup. Otherwise, you may observe incorrect painting on some operating systems (e.g. Windows 7).

Expanded Example

The following example handles the DrawItem event to custom paint non-working days within the dropdown calendar. These days are painted red (non-working days which don't belong to the currently displayed month are painted light pink).

The following image shows the result.
