Problem with worksheet protection


We upgraded from version to of Aspose.Cells. This code worked before the update:

' Instantiate an Workbook object that represents an Excel file
Dim newWorkbook As Workbook = New Workbook()

With newWorkbook.Worksheets(0)

' Set worksheet protection level - where locked cells are not allowed to be edited
.Protection.IsEditingContentsAllowed = False

' Import datatable to worksheet
.Cells.ImportDataTable(aDataTable, True, "A1")

' Set column properties
.Cells.Columns(0).Style.IsLocked = True ' Can't be edited
.Cells.SetColumnWidth(0, 0)
.Cells.Columns(1).Style.IsLocked = False
.Cells.SetColumnWidth(1, 80)
.Cells.Columns(2).Style.IsLocked = False
.Cells.SetColumnWidth(2, 80)

' Set source language header properties
With .Cells(0, 1).Style
.IsLocked = True ' Can't be edited
.BackgroundColor = Color.LightGray
End With

' Set target language header properties
With .Cells(0, 2).Style
.IsLocked = True ' Can't be edited
.BackgroundColor = Color.LightGray
End With

End With

' Save to excel file

After the upgrade this code generates a excel file that protects all cells, even tough only one column and two cells is locked(IsLocked = true). With other words the hole worksheet are protected now.
Waiting for your response.

thanks in advance,

Hi Masod,

We change the column style setting routine. Now Column.Style property is a read-only property. Please change your code as following to format column B and C.

Dim style As Style = .Cells.Columns(1).Style
style.IsLocked = False
Dim flag As StyleFlag
flag.Locked = True

.Cells.Columns(1).ApplyStyle(style, flag)

.Cells.SetColumnWidth(1, 80)

style = .Cells.Columns(2).Style
style.IsLocked = False

.Cells.Columns(2).ApplyStyle(style, flag)

Thanks! it helped.

A smaller problem how do i get the Color.LightGrey to work on cells?


Please create a style object and set the related style attributes and apply the style to your desired cell using Cell.SetStyle() method.


Dim wb As Workbook = New Workbook()

'Since Ms Excel color palette (56 colors ...0-55 indexed) does not contain light grey color by default,
'so you have to add it to the palette first.

Dim cells As Cells = wb.Worksheets(0).Cells
Dim cell As Cell = cells(0,0)

Dim styles As Styles = wb.Styles
Dim index As Integer = styles.Add()
Dim style As Style = styles(index)
style.ForegroundColor = Color.LightGray
style.Pattern = BackgroundType.Solid
style.Font.Color = Color.Red
style.HorizontalAlignment = TextAlignmentType.Center



Thank you.
