Example

This example demonstrates how to access columns in a worksheet. Use the Worksheet.Columns property to get a collection of columns contained in a worksheet (the ColumnCollection object). To get an individual column by its index (zero-based) or heading (“A”, “B”, “C”, etc.), use the ColumnCollection.Item property.

C#

using DevExpress.Spreadsheet;
// ...

Workbook workbook = new Workbook();

// Access a collection of columns.
ColumnCollection columns = workbook.Worksheets[0].Columns;

// Access the first column by its index in the collection of columns.
Column firstColumn_byIndex = columns[0];

// Access the first column by its unique name.
Column firstColumn_byName = columns["A"];

VB.NET

Imports DevExpress.Spreadsheet
' ...

Dim workbook As New Workbook()

' Access a collection of columns.
Dim columns As ColumnCollection = workbook.Worksheets(0).Columns

' Access the first column by its index in the collection of columns.
Dim firstColumn_byIndex As Column = columns(0)

' Access the first column by its unique name.
Dim firstColumn_byName As Column = columns("A")
