DataGrid问题？？？

[coolboyheyhey]

我是通过以下代码来连数据的：
Dim myconnection As SqlConnection = New SqlConnection("server=KEN;database=ISP;uid=sa;pwd=ISL")
Dim mydataadapter As New SqlDataAdapter
Dim mydataset As DataSet = New DataSet
mydataadapter.SelectCommand = New SqlCommand
mydataadapter.SelectCommand.Connection = myconnection
mydataadapter.SelectCommand.CommandText = "SELECT * FROM GBCUST"
mydataadapter.SelectCommand.CommandType = CommandType.Text
myconnection.Open()
mydataadapter.Fill(mydataset, "GBCUST")
myconnection.Close()
DataGrid1.DataSource = mydataset
DataGrid1.DataMember = "GBCUST"

问题：我现在想在DataGrid1中直接进行增加，修改，删除等操作，但我不知道代码应该怎么样写，望各位大哥帮帮小弟！！

直接读出datagrid一行的值，然后对通过查询，删除，修改对数据库进行操作，即可
