Cómo congelar una fila en Excel (Guía para principiantes)

2.1 Freeze Rows

In your worksheet, you might want to permanently display a specific row or column, particularly the header cells. You can scroll over your material while still viewing the frozen cells by freezing rows or columns in place.

Step 1: Select the row you want to freeze or, if you want to freeze the top row, select row 1. In this case, choose row 1 to freeze it to see the header at all times.

Step 2: Choose Freeze Panes from the drop-down menu by clicking the Freeze Panes command on the View tab.

Step 3: The gray line indicates that the rows are frozen in place. The frozen rows can still be viewed at the top of the worksheet as you scroll down. In this example, scroll down to row 17, but row 1 still can be seen on the screen because it has been frozen as the top row.

3.3 Freeze Panes using IronXL

Freezing rows and columns in Excel allows them to remain fixed in the specified location on the screen while scrolling, making it easier to keep track of columns and refer to them. Below is a sample code for freezing rows:

using IronXL;

// Load the existing Excel file
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Get a specific worksheet from the workbook
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Create a freeze pane at the top of the worksheet
// Parameters are column index and row index; here, it's freezing the top row
ws.CreateFreezePane(0, 1);

// Save the modified Excel file
wb.SaveAs("sample1.xlsx");

using IronXL;

// Load the existing Excel file
WorkBook wb = WorkBook.LoadExcel("sample1.xlsx");

// Get a specific worksheet from the workbook
WorkSheet ws = wb.GetWorkSheet("Sheet1");

// Create a freeze pane at the top of the worksheet
// Parameters are column index and row index; here, it's freezing the top row
ws.CreateFreezePane(0, 1);

// Save the modified Excel file
wb.SaveAs("sample1.xlsx");

Imports IronXL

' Load the existing Excel file
Private wb As WorkBook = WorkBook.LoadExcel("sample1.xlsx")

' Get a specific worksheet from the workbook
Private ws As WorkSheet = wb.GetWorkSheet("Sheet1")

' Create a freeze pane at the top of the worksheet
' Parameters are column index and row index; here, it's freezing the top row
ws.CreateFreezePane(0, 1)

' Save the modified Excel file
wb.SaveAs("sample1.xlsx")

The above code is a sample that freezes the top row of the Excel sheet.

1. Load the Existing Excel Sheet:
   Use the method WorkBook.LoadExcel to load the Excel file into the wb object, which can perform various types of Excel processes.

2. Select the Worksheet:
   Use GetWorkSheet to select the required worksheet by name (in this case, "Sheet1").

3. Create Freeze Panes:
   The method CreateFreezePane is used with two parameters - one for the column position and the other for the row position. It freezes the specified columns and rows in place.

4. Save the Workbook:
   Use the SaveAs method to save changes to a file.

Changing the values in CreateFreezePane can modify which rows and columns are frozen.
