When a user selects a shape, the Picture Tools contextual tab appears. Users can move, resize, rotate, and delete existing shapes. It does not contain user interface elements to create other shape types. The Rich Text Editor allows users to insert pictures and text boxes only. The Rich Text Editor supports all shape types from simple lines and rectangles to shapes with advanced effects. The WinForms Rich Text Editor allows you to view, print, and export documents that contain shapes to PDF. Refer to the A1498 - Is custom drawing ignored when printing or exporting? KB article to learn how to keep your customizations.Shapes, Pictures, and Other Graphic Objects in Rich Text Documents Note that the CustomDrawCell event is ignored when printing\exporting Grid data. Refer to the Custom Painting Basics and Custom Painting Scenarios articles for more information. See “Example 2” in this article for a sample code. You can draw cells with the default painter (call the CustomDrawEventArgs.DefaultDraw method to do that), and then add custom-painted elements on top of these cells. Otherwise, your custom appearance can be lost. Once you have performed required custom draw actions, set the e.Handled parameter to true to prevent the default renderer from changing this cell. You can call BaseView.LayoutChanged method to trigger the event. If you subscribe to this event at runtime, your event handler is raised next time the Grid layout changes. To identify the currently processed cell, read the event’s RowCellCustomDrawEventArgs.RowHandle and RowCellCustomDrawEventArgs.Column parameters. The CustomDrawCell event is raised before a data cell is painted. Paints the required HTML template inside an element that raised this event. The context parameter allows you to assign an object that transfers mouse events to template elements. The event data class exposes the following methods: MethodĭrawHtml(HtmlTemplate, DxHtmlPainterContext, Action) Gets the handle of a painted element’s row. Gets or sets a value specifying whether an event was handled and that the default element painting is therefore not required. Use the CustomDrawEventArgs.Cache property instead if you enable the DirectX hardware acceleration. Gets or sets the painted element’s display text.Ī GDI drawing surface. Gets the column whose element is being painted. Gets the painted value or display text (depending on the event). Provides information on the painted cell. See DirectX hardware acceleration to learn more. Provides methods to paint on drawing surfaces in GDI and DirectX modes. Returns a value specifying limits for the drawing area. Gets the painted element’s appearance settings. The following properties provide information specific to this event: The CustomDrawCell event's data class is RowCellCustomDrawEventArgs.
