How to hide certain columns and lock or unlock columns while exporting WinForms GridGroupingControl to Excel?

Platform: WinForms |
Control: GridGroupingControl


In order to hide some specific columns and also to lock or unlock columns while exporting from GridGroupingControl to Excel, the ShowColumn() method and the Locked property of worksheet can be used respectively.


ExcelEngine engine = new ExcelEngine();
IApplication app = engine.Excel.Application;
app.DefaultVersion = ExcelVersion.Excel2010;
IWorkbook book = app.Workbooks.Create();
IWorksheet sheet = book.Worksheets[0];
excelConverter.GroupingGridToExcel(this.gridGroupingControl1, sheet, ConverterOptions.Default);
// Hides the Column index "2".
sheet.ShowColumn(2, false);
// Locks the cell range B12
sheet.Range["B12"].CellStyle.Locked = true;
// Unlocks the cell range A2
sheet.Range["A2"].CellStyle.Locked = false;
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = this.saveFileDialog1.FileName;


Dim engine As New ExcelEngine()
Dim app As IApplication = engine.Excel.Application
app.DefaultVersion = ExcelVersion.Excel2010
Dim book As IWorkbook = app.Workbooks.Create()
Dim sheet As IWorksheet = book.Worksheets(0)
excelConverter.GroupingGridToExcel(Me.gridGroupingControl1, sheet, ConverterOptions.Default)
' Hides the Column index "2".
sheet.ShowColumn(2, False)
' Locks the cell range B12
sheet.Range("B12").CellStyle.Locked = True
' Unlocks the cell range A2
sheet.Range("A2").CellStyle.Locked = False
Dim proc As New System.Diagnostics.Process()
proc.StartInfo.FileName = Me.saveFileDialog1.FileName
