Event Data

The event handler receives an argument of type MedicalViewerPaintInformationEventArgs containing data related to this event. The following MedicalViewerPaintInformationEventArgs properties provide information specific to this event.

Property	Description
CellIndex	Gets the value that indicates the index of the cell that is to be painted. This value is only valid if the cell is add to the MedicalViewer.
ClipRectangle (Inherited from System.Windows.Forms.PaintEventArgs)	Gets the rectangle in which to paint.
Draw	Gets or sets the value that indicates whether to make the control draw the sub-cell. This is used only with the MedicalViewerCell.PrePaint event.
Graphics (Inherited from System.Windows.Forms.PaintEventArgs)	Gets the graphics used to paint.
ImageRectangle	Gets the rectangle that represents the image rectangle for the cell or sub-cell.
SubCellIndex	Gets the value that indicates the index of the sub-cell that is to be painted.
