Gridview_RowEdition de valeurs vides

2011-05-09 5 views

J'ai un contrôle gridview auquel je lie manuellement les données. Lorsque je modifie une ligne et la mets à jour, les valeurs des zones de texte envoyées sont toujours les anciennes valeurs. J'ai trouvé quelques discussions à ce sujet mais je n'ai pas eu de chance d'extraire les nouvelles valeurs.Gridview_RowEdition de valeurs vides

<asp:GridView ID="GridView1" runat="server"> 
     <Columns> 
      <asp:CommandField ShowEditButton="True" /> 
     </Columns> 
    </asp:GridView> 



    Private Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView1.RowUpdating 
     Dim gv As GridView = sender 
     For i As Integer = 0 To gv.Columns.Count Step 1 
      Dim cell As DataControlFieldCell = gv.Rows(e.RowIndex).Cells(i) 
      gv.Columns(0).ExtractValuesFromCell(e.NewValues, cell, DataControlRowState.Edit, True) 
     Next 
     For Each s As DictionaryEntry In e.NewValues 
      Debug.Print(s.Key & " | " & s.Value) 
     Next 

     ds.Tables("testTable").Rows(e.RowIndex).BeginEdit() 
     [ ... ] 
     ds.Tables("testTable").Rows(e.RowIndex).EndEdit() 

     GridView1.EditIndex = -1 

     BindData() 
    End Sub

Je veux aussi souligner que le code ExtractValuesFromCell est juste ma dernière tentative pour obtenir les nouvelles données. Avant que j'utilisais quelque chose comme ça

Dim tb as TextBox = sender.Rows(e.RowIndex).Cells(1).Controls(0) 
Label1.Text = tb.Text

Aussi voici comment les données semble commencer

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    If (ds.Tables.Count = 0) Then 
     ds.Tables.Add("testTable") 
     ds.Tables("testTable").Columns.Add("Driver Name") 
     ds.Tables("testTable").Columns.Add("Total") 
     ds.Tables("testTable").Columns.Add("# Of Calls") 
     ds.Tables("testTable").Columns("Total").ReadOnly = True 
     ds.Tables("testTable").Columns("# Of Calls").ReadOnly = True 

     Dim newRow As DataRow = ds.Tables("testTable").NewRow() 
     newRow("Driver Name") = "" 
     newRow("Total") = "" 
     newRow("# Of Calls") = "" 
     ds.Tables("testTable").Rows.Add(newRow) 
    End If 
    BindData() 
End Sub

Ceci est un grand tas de code sans aucune explication. Pourriez-vous s'il vous plaît expliquer aussi ce qu'il fait? –
