Forms Data Controls :: Gridview And Excel As Datasource?
Mar 26, 2010
im using an excel file as a datasource for my gridview...i can pull all the data into the gridview fine. i am now hoping to allow the user to update the data in the excel file through the gridview. is it possible to update the excel file in this format i.e. allow the user the read/update the excel file as if its a database. i see some references in google that its not possible to update the excel file as the writeout causes problems. does anyone have this working...or should i look into trying to use another datasource.
i was hoping to use an excel file as the app is on a shared server and it would be handy just to have the excel file in the app folder as there is not much data involved.

I have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
