The WPF Spreadsheet control allows you to view, print, and export documents that contain shapes to PDF/HTML. All shape types are supported: from simple lines and rectangles to banners and callouts.
Working with Shapes in UI
The SpreadsheetControl enables end-users to move, resize, rotate, or remove shapes in a document.
The SpreadsheetControl does not provide user interface elements that allow end-users to insert new shapes, edit existing shapes, and change their appearance.
An individual shape (Shape) is a member of the Worksheet.Shapes collection. The ShapeCollection collection stores all drawing objects embedded in a worksheet (shapes, pictures, and charts). You can access an existing shape by its index in the shape collection or using the ShapeCollection.GetShapeById method. The Shape.ShapeType property allows you to distinguish between different drawing object types within a worksheet.
The ShapeCollection and Shape interfaces provide methods and properties designed to manipulate shapes in a document.
