Worksheets and Chart Sheets
A workbook consists of one or more worksheets stored in the IWorkbook.Worksheets collection. When you create a SpreadsheetControl instance, it contains a workbook with an empty worksheet. Use the WorksheetCollection members to add a new worksheet, remove an existing worksheet, rename a worksheet, select an active worksheet, and so on.
The IWorkbook.Sheets collection stores all sheets (worksheets and chart sheets) in a workbook. Use this collection to obtain a sheet of any type.
Built-in and Custom Functions
You can include functions in your formulas to perform calculations. Use the IWorkbook.Functions property to access the WorkbookFunctions object that stores all built-in functions and allows you to override any function via the WorkbookFunctions.OverrideFunction method.
You can also create a custom function. To add a custom function to a workbook, define a class that implements the ICustomFunction interface and add its instance to the IWorkbook.CustomFunctions or IWorkbook.GlobalCustomFunctions collection.
Custom functions are not saved. To replace custom function definitions with calculated values when a workbook is saved, set the SpreadsheetExportOptions.CustomFunctionExportMode option to CalculatedValue.
Table and Pivot Table Styles
The IWorkbook.TableStyles collection stores styles you can apply to tables and pivot tables. You can select a built-in style or create a custom style.
Custom XML Parts
You can embed arbitrary XML data in workbooks in Excel file formats. This data is named custom XML parts and stored in the IWorkbook.CustomXmlParts collection. Use the collection's members to create and modify custom XML parts.
