Aspose.Cells .NET: support for Excel 2007 features

Aspose.Cells Product Family
1

Hello,


I am evaluating two Excel components: Aspose.Cells and TMSSoftware’s FlexCel. I’m specifically looking for Excel 2007 support of the following features:

- Sheet, row and cell-level locking via protection. Specifically:
- Lock rows entirely (no new rows or deleted rows)
- Lock specific cells from edits
- Hide/Lock an entire sheet

- Ability to carry through add-ins in an existing worksheet or add add-ins to a newly generated worksheet.

- Ability to add auto-filter to specific columns

According to this in your overview (https://docs.aspose.com/cells/net/product-overview) these features are supported, but are they fully supported in Excel 2007? I have been working more with FlexCel, and have recently discovered that they do not support row/cell level locking in the .xslx format.

Thank you for your time,
Jim

Hi Jim,

Thanks for considering Aspose.

Aspose.Cells for .NET supports your desired features for Excel 2007 formats.

For your desired features:

  • Sheet, row and cell-level locking via protection. Specifically:
  • Lock rows entirely (no new rows or deleted rows)
  • Lock specific cells from edits
  • Hide/Lock an entire sheet

Yes, these features are supported for Excel 2007 formats, see the sample examples below:

  1. To protect an entire sheet in an existing Excel 2007 Xlsx file.
    //Instantiating a Workbook object
    Workbook excel = new Workbook();
    //Creating a file stream containing the Excel file to be opened
    FileStream fstream = new FileStream(“e:\test\Book1.xlsx”, FileMode.Open);
    //Opening the Excel file through the file stream
    excel.Open(fstream,FileFormatType.Excel2007Xlsx);
    //Accessing the first worksheet in the Excel file
    Worksheet worksheet = excel.Worksheets[0];
    //Protecting the worksheet with a password
    worksheet.Protect(ProtectionType.All, “amjad”, null);
    //Saving the modified Excel file in default (that is Excel 20003) format
    excel.Save(“e:\test\outputBook1.xlsx”);
    //Closing the file stream to free all resources
    fstream.Close();

  2. To Protect some cells in a sheet for Excel 2007 Xlsx format.
    // Create a new workbook.
    Workbook wb = new Workbook();
    // Create a worksheet object and obtain the first sheet.
    Worksheet sheet = wb.Worksheets[0];
    // Define the style object.
    Style style;
    //Define the styleflag object
    StyleFlag styleflag;
    // Loop through all the columns in the worksheet and unlock them.
    for (int i = 0; i <= 255; i++)
    {

style = sheet.Cells.Columns[(byte)i].Style;
style.IsLocked = false;
styleflag = new StyleFlag();
styleflag.Locked = true;
sheet.Cells.Columns[(byte)i].ApplyStyle(style, styleflag);

}

// Lock the three cells…i.e. A1, B1, C1.
style = sheet.Cells[“A1”].Style;
style.IsLocked = true;
sheet.Cells[“A1”].Style = style;
style = sheet.Cells[“B1”].Style;
style.IsLocked = true;
sheet.Cells[“B1”].Style = style;
style = sheet.Cells[“C1”].Style;
style.IsLocked = true;
sheet.Cells[“C1”].Style = style;

// Finally, Protect the sheet now.
sheet.Protect(ProtectionType.All);
// Save the excel file.
wb.Save(“e:\test\lockedcells.xlsx”);
