Enabling editing in a gridview

Hi
I am populating a gridview with the code below, how can I enable editing like you get if setup through using the gui?
Using Visual Studio 2010 vb.net

        Dim conString = ConfigurationManager.ConnectionStrings("clientsConnectionString")
        Dim strConnString As String = conString.ConnectionString
        Dim myConnection As SqlConnection
        Dim myCommand As SqlDataAdapter
       
        myConnection = New SqlConnection(strConnString)

        myCommand = New SqlDataAdapter("SELECT matter,client,mattername FROM client1 where client like '%" & txtClient.Text & "%' and matter like '%" & txtMatter.Text & "%' and mattername like '%" & txtMattername.Text & "%'", myConnection)

        ' Create and fill a DataSet.
        Dim ds As DataSet = New DataSet()
        myCommand.Fill(ds)

        grdClientres.DataSource = ds
        grdClientres.DataBind()
