Spreadsheet for ASP.NET Web Forms - How to save/load documents to/from a database

This example demonstrates how to configure the Spreadsheet control to work with a database.

Overview

During page initialization, load a document from a database as a byte array and pass it to the control's Open method to open the document in the Spreadsheet.

The Saving event occurs when a user clicks the built-in Save or SaveAs command in the Spreadsheet's Ribbon UI. To save changes, handle the Saving event and update the data source. To save the document after a user clicks a custom button, update the database in the button's Click event handler.

Note
When a user changes a cell value, the Spreadsheet control applies the entered value only after the user moves focus to another cell. A new cell value cannot be saved until the control applies it. To apply the pending cell value change, call the ApplyCellEdit method.
