Gridview_RowEditing 빈 값

Question

데이터를 수동으로 바인딩하는 gridview 컨트롤이 있습니다. 행을 편집하고 업데이트 할 때 보낸 텍스트 상자의 값은 항상 이전 값입니다. 이 스레드를 발견했지만 새로운 값을 추출하지 못했습니다.

<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 

또한 ExtractValuesFromCell 코드는 새로운 데이터를 가져 오는 가장 최근의 시도임을 지적하고자합니다. 그 전에는 내가 여기 또한이

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

같은 것을 사용하고 그렇지 않으면 새 값이 덮어 씁니다, 데이터가 당신은 당신의 GridView 경우에만 Not Page.IsPostback을 데이터 바인딩해야

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
