Whenever you are working with lots of data, it can be difficult to compare information in your workbook. You may want to see certain rows or columns all the time in your worksheet, especially header cells. By freezing rows or columns in place, you can keep rows or columns visible while scrolling through the rest of the worksheet.
In the following sections, I will demonstrate how to freeze Excel panes in WPF.
Step 1: Initialize a new instance of Workbook class. Load the word document from the file.
Workbook workbook = new Workbook();
workbook.LoadFromFile("SalesReport.xlsx");
Step 2: In our example, my workbook has several worksheets. We want to check the data from the second worksheet. Therefore, we select the second worksheet.
Worksheet sheet = workbook.Worksheets[1];
Step 3: In this case, we want to fix the first two rows and the leftmost column. The row and column will be frozen in place, as indicated by the solid grey line.
sheet.FreezePanes(2, 1);
Step 4: Save the workbook and launch the file.
workbook.SaveToFile("SalesReport Result.xlsx");
System.Diagnostics.Process.Start("SalesReport Result.xlsx");

//Select the second worksheet
Worksheet sheet = workbook.Worksheets[1];
//Select to freeze the first two rows and the leftmost column
sheet.FreezePanes(3, 2);
//Save and Launch
workbook.SaveToFile("SalesReport Result.xlsx");
System.Diagnostics.Process.Start("SalesReport Result.xlsx");
