Hello,

Thanks for your inquiry.
Our Spire.Spreadsheet supports showing and hiding rows/columns. You could refer to the following guide to add Spire.Spreadsheet controls to Toolbox, and then to view and show/hide the rows/columns of your Excel file. If you have other questions, just feel free to contact us.

Hello,

Thanks for your quick response.
If you just want to set the columns and rows visibly/invisibly by code, but not need to view the Excel at the same time. You could refer to below code of our Spire.XLS to achieve.
Code: Select all
Dim workbook As New Workbook()
workbook.LoadFromFile("sample.xlsx")
Dim sheet As Worksheet = workbook.Worksheets(0)
sheet.HideRow(2)
sheet.HideColumn(3)
sheet.ShowRow(4)
sheet.ShowColumn(5)
workbook.SaveToFile("result.xlsx", Spire.Xls.FileFormat.Version2013)

Otherwise, if you need to view the Excel file when setting the columns and rows visibly/invisibly, you have to use our Spire.Spreadsheet. It supports hiding and showing the columns and rows directly, you also could set them by yourself. Below is the code snippet for your better reference.
Code: Select all
Private Sub hideRowToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles hideRowToolStripMenuItem.Click
   For i As Integer = spreadsheet1.ActiveWorksheet.GetSelectedRange().Top To spreadsheet1.ActiveWorksheet.GetSelectedRange().Bottom
      spreadsheet1.ActiveWorksheet.Rows(i).IsHidden = True
   Next i
End Sub

Private Sub hideColumnsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles hideColumnsToolStripMenuItem.Click
   For i As Integer = spreadsheet1.ActiveWorksheet.GetSelectedRange().Left To spreadsheet1.ActiveWorksheet.GetSelectedRange().Right
      spreadsheet1.ActiveWorksheet.Columns(i).IsHidden = True
   Next i
End Sub

Private Sub unhideRowsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles unhideRowsToolStripMenuItem.Click

   For i As Integer = spreadsheet1.ActiveWorksheet.GetSelectedRange().Top To spreadsheet1.ActiveWorksheet.GetSelectedRange().Bottom
      spreadsheet1.ActiveWorksheet.Rows(i).IsHidden = False
   Next i
End Sub

Private Sub unhideColumnsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles unhideColumnsToolStripMenuItem.Click
   For i As Integer = spreadsheet1.ActiveWorksheet.GetSelectedRange().Left To spreadsheet1.ActiveWorksheet.GetSelectedRange().Right
      spreadsheet1.ActiveWorksheet.Columns(i).IsHidden = False
   Next i
End Sub

If there is any doubt, welcome to write back.

Sincerely,
Lisa
