C# - Updating Records In SQL Server 2005?

Jul 26, 2009

I have ALWAYS used the SQLDataSource to update my records in my SQL Server 2005 database, so i am not really sure how this would be done in normal code. I am using VB.NET but if you are a C# developer and want to show me some code that is more than welcome as well.

I am using ASP.NET 3.5.My user will see a page with 5 Text boxes with their contact details in. Those details I will get from a SQL Server DB and when they go and change the text in the text box and click submit, it must then save the changes.

This is very easy with the SQLDataSource but how can i code this myself?

[2008] Adding Records To DGV - But Not Updating The PK Field

Feb 7, 2009

I know that when I add a record to a table through a binding source using a binding navigator - it completely handles the IDENTITY PK (it's bound to a textbox and you can see it immediately).

Now I'm trying to do this differently in another part of the program - here I only have a BINDING SOURCE - that's bound to a DATAGRIDVIEW.

I put a new record into the DGV like this

Private Sub vendorfilesDGV_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles vendorfilesDGV.DragDrop
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
