With the DevExpress ASP.NET Spreadsheet (ASPxSpreadsheet), you can easily provide end-users the ability to view and modify Excel workbooks in a browser. The ASPxSpreadsheet can read and write files in XLS, CSV, TXT, and other formats. You can allow end-users to perform file management operations (such as creating a new spreadsheet, opening an existing spreadsheet or saving a spreadsheet) via the corresponding ribbon command buttons. These buttons are available in the File tab of the built-in ribbon.
This demo illustrates how easy it is to use the ASPxSpreadsheet to open and save spreadsheet documents in different formats. Simply drop the ASPxSpreadsheet control onto a form and set a single property - WorkDirectory. This property specifies the folder on the server where documents should be opened or saved.
