Frozen Rows are always shown at the top of the SheetView when a user scrolls down.
The default value is 0, which unfreezes all Rows. However, the value can be a number between 0 and 1048576. A value of 1048576 would freeze all Rows in the Worksheet; if a value of 3 was to be used, the first three Rows of the Worksheet would be frozen & would always be seen at the top of the SheetView, no matter how far the user scrolls down.
Note that the freeze will always start with the first Row in the Worksheet.
Freezes the first five rows and the first column: using( var workbook = Workbook.Load( "test.xlsx" ) ) { // Freezes the first 5 rows and adds a Fill Background to them. worksheet.SheetView.FrozenRows = 5; worksheet.Rows[ 0, 4 ].Style.Fill.BackgroundColor = System.Drawing.Color.Turquoise; // Freezes the first column and adds a Fill Background to it. worksheet.SheetView.FrozenColumns = 1; worksheet.Columns[ 0 ].Style.Fill.BackgroundColor = System.Drawing.Color.Tan; // Saves the workbook to disk. workbook.SaveAs( "FreezeRowsColumns.xlsx" ); }
