    Locked Property (XLSheet)
    In This Topic
    Gets or sets a value that determines if the sheet is locked for editing.
    Syntax
    'Declaration
     
    
    Public Property Locked As Boolean
    public bool Locked {get; set;}
    Remarks

    Sheets and styles can be locked. By default, sheets are unlocked and styles are locked. This combination allows users to edit the cells in Excel.

    To protect a cell against editing in Excel, both the sheet and the cell style must have the Locked property set to true.

    To lock most cells on a sheet and allow editing of only a few cells, lock the sheet, then create an unlocked style and assign it to the cells that should be editable.

    Example
    The code below creates a data entry sheet. Most cells are locked, except for the ones where the user is supposed to enter data.
    // start with a single locked sheet
    _c1xl.Clear();
    XLSheet sheet = _c1xl.Sheets[0];
    sheet.Locked = true;
                
    // create an unlocked style
    XLStyle dataEntry = new XLStyle(_c1xl);
    dataEntry.Locked = false;
    dataEntry.BackColor = Color.Beige;
                
    // create data entry titles
    sheet[0,0].Value = "Name:";
    sheet[1,0].Value = "Address:";
    sheet[2,0].Value = "Phone #:";
                
    create data entry cells (unlocked)
    sheet[0,1].Style = dataEntry;
    sheet[1,1].Style = dataEntry;
    sheet[2,1].Style = dataEntry;
                
    // save the book
    _c1xl.Save(@"c:\temp\Protected.xls");
