The DevExpress ASP.NET Spreadsheet (ASPxSpreadsheet) enables you to programmatically specify the worksheet area that is visible in the ASPxSpreadsheet and that allows end-user input.
Use the SetSize method available through the WorksheetDisplayArea property to limit the maximum number of rows and columns to be displayed in a specific sheet. This restricts end-users from accessing worksheet cells through a control's UI. This restriction, however, is not in effect for programmatic cell manipulation so you can change the content and format of each worksheet cell in code.
