This example demonstrates how to control the visibility of rows and columns in a worksheet using the Row.Visible and Column.Visible properties.
You can also hide a row or column in a worksheet by setting the row height (Row.Height) or column width (Column.Width, Column.WidthInCharacters or Column.WidthInPixels) to 0, respectively.
A complete sample project is available at https://github.com/DevExpress-Examples/wpf-spreadsheetcontrol-api-part-1-e4938.
Worksheet worksheet = workbook.Worksheets;
// Hide the 8th row of the worksheet.
worksheet.Rows.Visible = false;
// Hide the 4th column of the worksheet.
worksheet.Columns.Visible = false;
Dim worksheet As Worksheet = workbook.Worksheets(0)
' Hide the 8th row of the worksheet.
worksheet.Rows(7).Visible = False
' Hide the 4th column of the worksheet.
worksheet.Columns(3).Visible = False
