Unlock specific column from protected excel sheet using C#.NET

Hi Team,

I want to unlock only specific column from protected worksheet from excel.
But from following I am unable to lock specific column.

Platform : .Net

------------------------Dummy Code -------------------------
this.worksheet.Protect(ProtectionType.All, β€œtest”, null);
Style editstyle = workbook.CreateStyle();
StyleFlag editFlag = new StyleFlag { Locked = false };
this.worksheet.Cells.Columns[7].ApplyStyle(editstyle, editFlag);

Thanks :slight_smile:
Happy Coding

@sachinmali26,
You need to set the Style.IsLocked = true to set the style as locked and StyleFlag.Locked = true to cconsider this feature among all the styles. Also for column β€˜G’ use index 6 instead of 7.

Here is a complete example that unlocks the desired column while rest of the cells are protected. Please give it a try and share the feedback.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET

// Create a new workbook.
Workbook wb = new Workbook();

// Create a worksheet object and obtain the first sheet.
Worksheet sheet = wb.Worksheets[0];

// Define the style object.
Style style;

// Define the styleflag object.
StyleFlag flag;

// Protect all the cells in the sheet
style = sheet.Cells.Style;
style.IsLocked = true;
flag = new StyleFlag();
flag.Locked = true;
sheet.Cells.ApplyStyle(style, flag);

// Get the target column style.
style = sheet.Cells.Columns[6].Style; //For Columnn G as shown in your image

// Unlock it.
style.IsLocked = false;

// Instantiate the flag.
flag = new StyleFlag();

// Set the lock setting.
flag.Locked = true;

// Apply the style to the seventh column.
sheet.Cells.Columns[6].ApplyStyle(style, flag);

// Protect the sheet.
sheet.Protect(ProtectionType.All,"test", null);

// Save the excel file.
wb.Save("output.xlsx");
