The Where method limits the results to only those rows where the Hidden property of the item is not null and the value of the Hidden property is True.
It starts by calling the Descendants method of the worksheet, retrieving a list of all the rows. This single line accomplishes a lot, however. Select(Function(r) r.RowIndex.Value).ToList() Where(Function(r) r.Hidden IsNot Nothing AndAlso Where((r) => r.Hidden != null & r.Hidden.Value).

The code that actually retrieves the list of hidden rows requires only a single line of code. Retrieve information about rows or columns. You specified when you called the method to determine whether to The code uses the detectRows parameter that Retrieving the List of Hidden Row or Column Index Values (WorksheetPart)(wbPart.GetPartById(theSheet.Id)) ĬType(wbPart.GetPartById(theSheet.Id), WorksheetPart) Information you already retrieved provides an Id property, and given that Id property, the code can retrieve a reference to the corresponding WorksheetPart property by calling the GetPartById method of the WorkbookPart object.
Now that you have information about the sheet, the code must retrieve a reference to the corresponding worksheet part.
Null reference, and throws an exception if you passed in an invalid sheet name. The FirstOrDefault method returns either the first matching reference (a sheet, in this case) or a null reference if no match was found. Where(Function(s) s.Name = sheetName).FirstOrDefault() Throw new ArgumentException("sheetName") ĭim theSheet As Sheet = (Of Sheet)(). Where((s) => s.Name = sheetName).FirstOrDefault() The simplest way to accomplish this is to use a LINQ query. It simply finds a reference to a Sheet object, which contains information such as the name and Id property of the sheet. Note that this search simply looks through the relations of the workbook, and does not actually find a worksheet part. The code must look through all the sheet-type descendants of the workbook part's Workbook property, examining the Name property of each sheet that it finds. To find the hidden rows or columns, the code must first retrieve a reference to the specified sheet, given its name. SpreadsheetDocument.Open(fileName, False)ĭim wbPart As WorkbookPart = document.WorkbookPart WorkbookPart wbPart = document.WorkbookPart SpreadsheetDocument.Open(fileName, false)) Next the code retrieves a reference to the workbook part, by using the WorkbookPart property of the document. Next, the code opens the document, by using the SpreadsheetDocument.Open method and indicating that the document should be open for read-only access (the final false parameter value). The code starts by creating a variable, itemList, that will contain the return value. GetHiddenRowsOrCols(fileName, "Sheet1", True) const string fileName = items = GetHiddenRowsOrCols(fileName, "Sheet1", true) Ĭonst fileName As String = "C:\Users\Public\Documents\RetrieveHiddenRowsCols.xlsx" The method returns a list of unsigned integers that contain each index for the hidden rows or columns, if the specified worksheet contains any hidden rows or columns (rows and columns are numbered starting at 1, rather than 0.) To call the method, pass all the parameter values, as shown in the following example code. String fileName, string sheetName, bool detectRows)īyVal fileName As String, ByVal sheetName As String,īyVal detectRows As Boolean) As List(Of UInteger) Whether to detect rows (true) or columns (false) (Boolean). The name of the sheet to examine (string). The name of the document to examine (string). To retrieve a list of the hidden rows or columns in a worksheet. You can use the GetHiddenRowsOrCols method You must also use the following using directives or Imports statements to compile the code in this topic. You must explicitly reference the following assemblies in your project:ĭocumentFormat.OpenXml (installed by the Open XML SDK)
