Updating dataadapter access
i was only concerned about the values in the dropdownlist…coloursadapter was only the source for the dropdown for colour field not for the grid… IT is used in 2 or even 3 grids on the page so i wanted to have it as a little widget… In Lesson 3, we discussed a fully connected mode of operation for interacting with a data source by using the Sql Command object. Try it, i guess you are able to connect sql server database file (sql express) without installing sql server instance. Can you put sql database in app_data folder then connect it? The field count is correct, but there are 0 rows in the table.
For that reason, I'm using OLE DB to connect to a MS-Access database instead.
A Data Set is an in-memory data store that can hold numerous tables.
Data Sets only hold data and do not interact with a data source.
The SELECT query always returns data when called on a command object using Execute Reader().
(Note that I've used this query both with and without the enclosing brackets around the field names.) Because of this failure, I attempted to use a Data Adapter instead. Update Command = update Command; Data Table dat Users = new Data Table(); retrieve Command.
