There are several Clipboard operations (such as copy, cut, and paste) that are automatically set for a sheet with default settings; they are built-in to Spread. But Spread also gives you the ability to customize these operations on actual applications that you develop, depending on your specific needs. You can customize how the user can interact with the contents of the Clipboard when users perform copying and pasting actions in cells in the spreadsheet. You can implement those operations at your discretion in code. These customizations include:

• Deactivating clipboard operations
• Excluding headers from clipboard operations
• Obtaining the clipboard contents
• Deactivating pasting
• Changing the scope of pasting
• Performing the clipboard operations in code

The following members are used to determine Clipboard-related interaction:

• ClipboardOptions property (and ClipboardOptions enumeration)
• AutoClipboard property
• ClipboardCopyOptions enumeration
• ClipboardPasteOptions enumeration

The spreadsheet methods in the SheetView class that involve Clipboard operation are:

• ClipboardCopy, which copies the contents from the sheet to the Clipboard
• ClipboardCut, which cuts the contents from the sheet to the Clipboard
• ClipboardPaste, which pastes the contents from the Clipboard to the sheet

The corresponding shape methods in the SheetView class that involve Clipboard operation are:

• ClipboardCopyShape, which copies the active shape to the Clipboard
• ClipboardCutShape, which cuts the active shape to the Clipboard
• ClipboardPasteShape, which pastes the shape from the Clipboard

If there are locked cells in the range to cut or paste then the Clipboard operation is not performed.

You can also set how some Clipboard-related features perform when the user is in edit mode in a cell on the Spread. You can set whether the pop-up menu appears while in edit mode within a cell using the AutoMenu property in SuperEditBase class and whether the user can perform Clipboard operations with the shortcut keys with the AllowClipboardKeys property in SuperEditBase class.

Deactivating Clipboard Operations

You can set whether the shortcut keys are available to the end user for them to use to perform Clipboard operations by setting the AutoClipboard property in the FpSpread class. You can deactivate all the Clipboard operations with components by setting the AutoClipboard property to False in the FpSpread class. The default setting is True. You can deactivate some Clipboard operations such as pasting (Ctrl+V) by deactivating the input map definition for short-cut keys and Clipboard operations (Ctrl+C, Ctrl+V, and Ctrl+X).

Excluding Headers from Clipboard Operations

You can set whether to include headers when using Clipboard operations by setting the ClipboardOptions property in the FpSpread class and the ClipboardOptions enumeration. The default setting, AllHeaders, allows all headers to be included.

Obtaining the Clipboard Contents

Values which are copied on sheets are controlled by the Clipboard class which is provided from the .NET Framework. You can obtain Clipboard contents by using respective operations in this Clipboard class.

Cell data is copied onto the Clipboard in advance by calling ClipboardCopy method in the SheetView class at the Load event. Then, calling GetDataObject method enables you to obtain those Clipboard contents for use, such as for text format determination.

Deactivating Pasting

The ClipboardPasting event occurs when pasting is performed (Ctrl+V) on sheets. You can deactivate pasting by canceling this event under certain circumstances. You can prevent pasting by obtaining the timing when pasting is performed, and canceling the action.

Changing the Scope of Pasting

When cells are copied or cut to the Clipboard, all the data aspects including values, formats, and formulas, are available by default for pasting. You can configure to paste values only, for example, by changing the input map definitions. The default setting is ClipboardPasteAll, which enables pasting all the aspects of the data. The ClipboardPasteOptions enumeration allows you to set the scope of what is pasted when a Clipboard paste is performed by the user.

Disabling Pasting in Invisible Cells

You can set whether to paste the clipboard values in invisible cells, row, and columns by using the PasteSkipInvisibleRange option from the Features class. It accepts a boolean value and is False by default.

This option only takes effect when RichClipboard is set to True.

When PasteSkipInvisibleRange = True	When PasteSkipInvisibleRange = False (default value)

The following example allows you to skip pasting the data in an invisible range.

fpSpread1.LegacyBehaviors = LegacyBehaviors.None;
fpSpread1.Features.RichClipboard = true;
fpSpread1.ActiveSheet.Rows[7].Visible = false;
fpSpread1.ActiveSheet.Rows[10, 11].Visible = false;
fpSpread1.AsWorkbook().Features.PasteSkipInvisibleRange = true;

fpSpread1.LegacyBehaviors = LegacyBehaviors.None
fpSpread1.Features.RichClipboard = true
fpSpread1.ActiveSheet.Rows(7).Visible = false
fpSpread1.ActiveSheet.Rows(10, 11).Visible = false
fpSpread1.AsWorkbook().Features.PasteSkipInvisibleRange = true

Performing the Clipboard Operations in Code

Various methods are provided in the SheetView class for Clipboard processes. You can run them when you want. These include:

• ClipboardCopy
• ClipboardCopyShape
• ClipboardCut
• ClipboardCutShape
• ClipboardPaste
• ClipboardPasteShape
