I have spent the last day reading countless threads and webpages about updating a database with data entered into a datagrid.I have a datagrid with that I populate from an access database and the datagrid has 4 columns, 'Item Code','Description','Quantity' and 'Unit'.Another 3 columns ID, Division and Bid Refrence number are hidden. My aim was to use these as a unique reference so that I could update the changes made.I can show the datagrid just fine, no problems at all.
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty.

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:

[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database.
