How to set worksheet visibility to very hidden using .NET?

3 mins read
It is easy to hide and unhide worksheets in the .NET Excel library, but sometimes, you need to hide the worksheets so that they cannot be unhidden by others using the normal Unhide feature. In this case, a higher level of worksheet hiding - "very hidden" - can help you make the worksheets very hidden and not be displayed to others easily. Essential® XlsIO supports this feature in a very simple way by setting the worksheet’s visibility option.


To achieve this requirement, the workbook must contain more than one worksheet to be visible. The sample code to hide a worksheet to a very hidden state using XlsIO is given below.

 

C#

           
            ExcelEngine excelEngine = new ExcelEngine();
            // Step 1: Instantiate the Excel application object.
            IApplication application = excelEngine.Excel;
 
            // The workbook is opened.
            IWorkbook workbook = application.Workbooks.Create(3);
 
            // The first worksheet object in the worksheets collection is accessed.
            IWorksheet worksheet = workbook.Worksheets[1];
 
            // To set the visibilty of the worksheet
            worksheet.Visibility = WorksheetVisibility.StrongHidden;

VB

            
            Dim excelEngine As ExcelEngine = New ExcelEngine()
            'Step 1: Instantiate the Excel application object.
            Dim application As IApplication = excelEngine.Excel
 
            'The workbook is opened.
            Dim workbook As IWorkbook = application.Workbooks.Create(3)
 
            'The first worksheet object in the worksheets collection is accessed.
            Dim worksheet As IWorksheet = workbook.Worksheets(1)
 
            'To set the visibilty of the worksheet
            worksheet.Visibility = WorksheetVisibility.StrongHidden
