需要改變一個下拉列表後，它已被數據綁定到一個SQL數據源

Question

好吧，所以我有我的下拉列表數據綁定到一個SQL數據源，現在我需要改變數據在一些領域之前，它得到顯示。我這一切上午被搞亂，我無法找到任何有用的東西，這是我這麼遠，它顯然不工作...

Protected Sub ddlBookType_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlBookType.DataBound 
    'ddlBookType.Items.Insert(0, "Any") 
    Dim i As Integer 
    For i = 0 To ddlBookType.Items.Count - 1 
     If ddlBookType.Items(i).Attributes.Equals("mod_cook") Then 
      ddlBookType.Items(i).Text.Replace("mod_cook", "Modern Cooking") 
     End If 
    Next 
    End Sub

嘿，我剛剛做了它C＃並將其轉換爲VB（我希望它是正確的）。

下面的代碼（

Protected Sub ddlBookType_DataBound(sender As Object, e As EventArgs) 
    Dim ddlBookType As DropDownList = DirectCast(sender, DropDownList) 
    For Each item As ListItem In ddlBookType.Items 
     If item.Text = "mod_cook" Then 
      item.Text = "Modern Cooking" 
     End If 
    Next 
End Sub 

而這裏的原始的C＃代碼

protected void ddlBookType_DataBound(object sender, EventArgs e) 
{ 
    DropDownList ddlBookType = (DropDownList)sender; 
    foreach (ListItem item in ddlBookType.Items) 
    { 
     if (item.Text == "mod_cook") 
     { 
      item.Text = "Modern Cooking"; 
     } 
    } 
}
