Event Data

The CustomDrawEmptyArea event's data class is PivotCustomDrawEventArgs. The following properties provide information specific to this event:

Property Description
Appearance Gets the painted element's appearance settings.
Bounds Gets the bounding rectangle of the painted element.
Graphics Gets an object used to paint an element.
GraphicsCache Gets an object which specifies the storage for the most used pens, fonts and brushes.
Handled Gets or sets whether an event was handled, if it was handled the default actions are not required.
ThreadSafeArgs Gets an event parameter that provides thread-safe access to event data.

Remarks

Handle the CustomDrawEmptyArea event to custom paint the Pivot Grid Control's empty area. This is the area which isn't occupied by any rows. Set the event parameter's PivotCustomDrawEventArgs.Handled property to true to disable default background painting. The other properties of the event parameter provide you with all the necessary information to paint the background.

Important Note: custom drawing of any kind is ignored when printing PivotGridControl.

To access event data while an asynchronous operation is being performed, use a thread-safe event parameter returned by the PivotCustomDrawEventArgs.ThreadSafeArgs property. To learn more, see Asynchronous Mode.

IMPORTANT

Do not change cell values, modify the control's layout, or change the control's object model in the events used for custom control painting. Actions that update the layout can cause the control to malfunction.
