[VB.Net] ช่วยทีครับ DataGridView ทำค้นหา แก้ไข และลบข้อมูล

    Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtSearch.KeyDown
        If (e.KeyCode = Keys.Enter) Then
            Dim strID = Me.txtSearch.Text
            Dim objConn As New System.Data.SqlClient.SqlConnection
            Dim objCmd As New System.Data.SqlClient.SqlCommand
            Dim dtAdapter As New System.Data.SqlClient.SqlDataAdapter

            strID = strID.Trim.PadLeft(10, "0")
            txtSearch.Text = strID

            Dim dt As DataTable
            Dim strConnString, strSQL As String

            strConnString = "Server=localhost;UID=sa;PASSWORD=xxx;database=xxx;Max Pool Size=400;Connect Timeout=600;"

            strSQL = "SELECT * FROM tb_employee WHERE emp_id = '" & strID & "' "
            Dim dtFind As New DataTable
            Dim connection As New SqlConnection(strConnString)
            Dim dataadapter As New SqlDataAdapter(strSQL, connection)

            Dim ds As New DataSet
            connection.Open()
            dataadapter.Fill(ds, "Authors_table")
            connection.Close()
            DataGrid1.DataSource = ds
            DataGrid1.DataMember = "Authors_table"
        End If
    End Sub
