You have to add hidden column into the select query to retreive the data.
Hide the column from the DataGridView instead.
try
MysqlConn.Open()
Dim Query As String
Query = "select ID,LastName,FirstName,MiddleName,Address from god.precord"
COMMAND = New MySqlCommand(Query, MysqlConn)
SDA.SelectCommand = COMMAND
SDA.Fill(dbDataSet)
bSource.DataSource = dbDataSet
DataGridView1.DataSource = bSource
SDA.Update(dbDataSet)
DataGridView1.Columns("Address").Visible = false
MysqlConn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
MysqlConn.Dispose()
End Try
