输入datagridview的单元格时显示数据

Question

我有一个像这样的datagridview： datagridviewMut

我想直接在datagridview中输入数据。当我输入nip 123456789123456789时，我想从数据库中自动输出数据...并且我使用一个类从数据库中获取数据..但是它没有输出名称..

这是我使用visual basic的编码：

Private Sub DgvUMutasi_CellEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DgvUMutasi.CellEnter
    Dim columnName As String = DgvUMutasi.Columns(DgvUMutasi.CurrentCell.ColumnIndex).Name
    Dim row As DataGridViewRow = DgvUMutasi.CurrentRow

    cp.P_NIP = row.Cells(0).Value.ToString

    If columnName = "NIP" And cp.KeypressID() = True Then
        row.Cells(1).Value = cp.P_Nama
    End If
End Sub

这是keypressID的功能:(编辑：更改代码布局）

    Public Function KeypressID() As Boolean  
    Dim cnn As New SqlConnection(StrConn)  
    Dim cmmd As New SqlCommand  
    Dim dreader As SqlDataReader  
    Dim SQL As String  

    SQL = "SP_SELECT_PEGAWAI"

    cnn.Open()
    cmmd = New SqlCommand(SQL, cnn)
    cmmd.CommandType = CommandType.StoredProcedure
    cmmd.Parameters.Clear()
    cmmd.CommandText = SQL
    cmmd.Parameters.Add(New SqlParameter("@P1", NIP))
    dreader = cmmd.ExecuteReader

    If dreader.Read = True Then
        Dim ImgByte() As Byte = dreader("Foto")
        Dim ImgStr As New System.IO.MemoryStream(ImgByte)
        Me.Foto = Image.FromStream(ImgStr)
        Me.Nama = dreader("Nama")
        Me.Jabatan = dreader("Jabatan")
        Me.Daerah = dreader("Daerah")
        Me.Tsk = dreader("Tsk_Jab")
        Me.PktPns = dreader("Pnk_Pns")
        Me.GolPns = dreader("Gol_Pns")
        Me.TmtPns = dreader("Tmt_Pns")
        Me.Pensiun = dreader("Pensiun")
        Return True
    Else
        Me.Foto = Nothing
        Me.Nama = ""
        Me.Jabatan = ""
        Me.Daerah = ""
        Me.Tsk = Date.Now
        Me.PktPns = ""
        Me.GolPns = ""
        Me.TmtPns = Date.Now
        Me.Pensiun = Date.Now
        Return False
    End If
    cnn.Close()
End Function

哪一部分错了？
