This code example demonstrates how to save and restore ASPxSpreadsheet documents from a database using a Binary column.
Starting with version 15.1, we recommend using the ASPxSpreadsheet.Open method to load a document and call the ASPxSpreadsheet.SaveCopy method to save changes.
In version 15.2, it is also possible to handle the ASPxSpreadsheet.Saving event to save a document by clicking the ribbon's built-in Save button.
