Determine hidden Rows/Columns in within Range


I have defined a named range in Excel (“therange”). The Range includes a hidden row (line 8).

This is what I need to achieve:

· Get a handle on the named range using GetNamedRangesAndTables();

· Iterate through all cells in the range and determine if the cell is visible (e.g. is the according row or column hidden?)

Please see attached Excel-File as an example

How can I achieve that?


Thanks for the template file.

See the sample code below that denotes how to determine if a row is hidden in a range. I have used your template file in the code. You may refer to it and may add or update code accordingly for your needs:
Sample code:

// Open Excel file.
Workbook workbook = new Workbook(“e:\test2\HiddenRow.xlsx”);

//If you just want to know any row in referred range is hidden, you may determine as following:
Range range = workbook.Worksheets.Names[“therange”].GetRange();

if (range != null)

if (!range.Worksheet.IsVisible)

MessageBox.Show(“Worksheet is not visible.”);


Cells cells = range.Worksheet.Cells;

for (int i = range.FirstRow; i < (range.RowCount + range.FirstRow) ; i++)

if (cells.Rows[i].IsHidden)

Console.WriteLine(“Row " + (cells.Rows[i].Index +1).ToString() + " is hidden”);



//Similarly you may try to evaluate if any column is hidden
//…Your code goes here.


Hope, this helps a bit.

Thank you.
