Updating database from datagridview

I have a Data Grid View that is attached to a Binding Source that gets data from a SQL Server database.

I can populate the Data Grid View without a problem.

Bound mode is suitable for managing data using automatic interaction with the data store.

One very common use of the Data Grid View control is binding to a table in a database.

So, I begain experimenting by placing my update code into various events.

Enabled = False End Sub Private Sub delete_btn_Click(By Val sender As System.

Virtual mode gives you a higher degree of control by allowing you to wait until a cell is actually being displayed to provide the value it will contain.

The following C# source code illustrate how to connect a Data Grid View to a database and new/update or delete the database values from Data Grid View.

Unbound mode is suitable for displaying relatively small amounts of data that you manage programmatically. Click Dim connection String As String = "Data Source=.; Initial Catalog=pubs; Integrated Security=True" Dim sql As String = "SELECT * FROM Stores" Dim connection As New Sql Connection(connection String) connection.

Virtual mode gives you a higher degree of control by allowing you to wait until a cell is actually being displayed to provide the value it will contain. Sql Client Public Class Form1 Dim s Command As Sql Command Dim s Adapter As Sql Data Adapter Dim s Builder As Sql Command Builder Dim s Ds As Data Set Dim s Table As Data Table Private Sub load_btn_Click(By Val sender As System. Open() s Command = New Sql Command(sql, connection) s Adapter = New Sql Data Adapter(s Command) s Builder = New Sql Command Builder(s Adapter) s Ds = New Data Set() s Adapter.
