Thank you for considering Aspose.

Well, you can use different worksheet and cells protection option provided by Aspose.Cells to achieve your desired results. Following sample code protects the worksheet contents from getting edited and also sets the advance protection option of not allowing cells to be selected (as per xlNoSelection option).

``

Sample Code:

//Instantiating a Workbook object

Workbook excel = new Workbook();

//Opening the Excel file

excel.Open("C:\\book1.xls");

//Accessing the first worksheet in the Excel file

Worksheet worksheet = excel.Worksheets[0];

//protecting a worksheet with password

worksheet.Protect(ProtectionType.Contents, "aspose", "");

//disallowing users to select locked cells of the worksheet

worksheet.Protection.IsSelectingLockedCellsAllowed = false;

//disallowing users to select unlocked cells of the worksheet

worksheet.Protection.IsSelectingUnlockedCellsAllowed = false;

//Saving the modified Excel file Excel XP format

excel.Save("C:\\output.xls");

Also, to stop the selection of a specific cell, you can use the Cell.Style.isLock = true and use worksheet.Protection.IsSelectingLockedCellsAllowed = false. But in this scenario please remember that by default all the cells in a worksheet have the Style.isLocked property set to true, so if you want any of the cell to get selected you have to set its isLocked property to false manually through the code. Also, Excel’s advance protection only takes effect when you protect the worksheet.

Please see the following links for different other advance protection options,

Hi,

Thank you for considering Aspose.

Well, to restrict the selection of a specific cell, you can use the Cell.Style.isLock = true and use worksheet.Protection.IsSelectingLockedCellsAllowed = false. But in this scenario please remember that by default all the cells in a worksheet have the Style.isLocked property set to true, so you have to set the isLocked property of the cells you want to get selected to false manually through the code. Also, Excel’s advance protection only takes effect when you protect the worksheet. Please see the following Sample code in this regard,<?xml:namespace prefix = o ns = “urn:schemas-microsoft-com:office:office” />

Sample Code:

Workbook excel = new Workbook();

//Opening the Excel file

excel.Open(“C:\book1.xls”);

//Accessing the first worksheet in the Excel file

Worksheet worksheet = excel.Worksheets[0];

//Style Object

Style style;

//Style Flag

StyleFlag flag;

//Making all the Cells un-Locked

for (int i = 0; i <= 255; i++)

{

style = worksheet.Cells.Columns[(byte)i].Style;

style.IsLocked = false;

flag = new StyleFlag();

flag.Locked = true;

worksheet.Cells.Columns[(byte)i].ApplyStyle(style, flag);

}

style = worksheet.Cells.Rows[0].Style;

style.IsLocked = true;

flag = new StyleFlag();

flag.Locked = true;

worksheet.Cells[“A10”].Style.IsLocked = true;

//protecting a worksheet with password

worksheet.Protect(ProtectionType.Contents, “aspose”, “”);

//disallowing users to select locked cells of the worksheet

worksheet.Protection.IsSelectingLockedCellsAllowed = false;

//Saving the modified Excel file

excel.Save(“C:\output.xls”);
