SfSpreadsheet has History Manager class that supports the implementation of undo/ redo operations

By default, Undo/Redo operations in SfSpreadsheet is enabled. To disable the Undo/Redo operations, set the Enabled property of History Manager to be false.

Context menu in SfSpreadsheet is customizable menu which can be used for various functionalities

TabItem Context menu opens when the user right-click on the sheet tab and contains the menus related to worksheet operations.

By default, TabItem Context menu is enabled in SfSpreadsheet. To disable the TabItem context menu, set the AllowTabItemContextMenu property to false.

C#

Default TabItem context menu has options like Insert, Delete, Hide/Unhide and Protect sheet. You can also customize the TabItem Context menu by setting IsCustomTabItemContextMenuEnabled property to be true and you can add your customized menu items.

C#
spreadsheet.IsCustomTabItemContextMenuEnabled = true;
spreadsheet.TabItemContextMenu = CustomTabItemContextMenu();

//Custom TabItem ContextMenus

public ContextMenu CustomTabItemContextMenu()
{
    var contextMenu = new ContextMenu();
    var insertRowIcon = new Image() { Source = new BitmapImage(new Uri(@"..\..\Icon\insertRow.png", UriKind.Relative)) };
    var insertRow = new MenuItem() { Header = "InsertRow" };           
    insertRow.Icon = insertRowIcon;
    insertRow.Click += insertRow_Click;

    var deleteRowIcon = new Image() { Source = new BitmapImage(new Uri(@"..\..\Icon\deleteRow.png", UriKind.Relative)) };
    var deleteRow = new MenuItem() { Header = "DeleteRow"};
    deleteRow.Icon = deleteRowIcon;
    deleteRow.Click += deleteRow_Click;
    
    contextMenu.Items.Add(insertRow);
    contextMenu.Items.Add(deleteRow);
    return contextMenu;
 }

Cell Context menu opens when the user right-click on a worksheet cell or selection of cells in SfSpreadsheet.

By default, Cell Context menu is enabled in SfSpreadsheet. To disable the Cell Context menu, set the AllowCellContextMenu property as false.

Users can also customize the Cell Context menu of SfSpreadsheet by using CellContextMenuOpening Event of SpreadsheetGrid.

Adding the customized menu items in the CellContextMenuOpening Event,

C#
spreadsheet.ActiveGrid.CellContextMenuOpening += ActiveGrid_CellContextMenuOpening;

void ActiveGrid_CellContextMenuOpening(object sender, CellContextMenuOpeningEventArgs e)
{
    //Adding Customized Menu item
    MenuItem PasteSpecial = new MenuItem();
    PasteSpecial.Header = "Pastespecial";
    Image paste = new Image() { Source = new BitmapImage(new Uri(@"..\..\Icon\paste.png", UriKind.Relative)) };
    PasteSpecial.Icon = paste;
    spreadsheet.ActiveGrid.CellContextMenu.Items.Add(PasteSpecial);
        
    //Remove the existing Context menu
    spreadsheet.ActiveGrid.CellContextMenu.Items.RemoveAt(2);
}

TIPS

Custom Cell Context menu can also by added by assigning the customized menu items to the CellContextMenu property of SpreadsheetGrid. For your reference, CustomContextMenu
