DetailsView編輯和新按鈕不會改變DetailsView模式

我試圖編寫DetailsView但缺少一些編碼。你可以看看這個編碼，並讓我知道我錯過了什麼，因爲單擊編輯按鈕或新建按鈕不會改變DetailsView的模式，所以我可以輸入數據。DetailsView編輯和新按鈕不會改變DetailsView模式

這是在DetailsView編碼：

<asp:UpdatePanel 
    ID="UpdatePanelParentsSummary" 
    runat="server" 
    UpdateMode="Conditional"> 

    <ContentTemplate> 
     <asp:DetailsView 
      ID="DetailsViewParentsDetails" 
      runat="server" 
      Height="50px" 
      Width="404px" 
      AutoGenerateRows="False"> 

      <Fields> 
       <asp:TemplateField ShowHeader="False"> 

        <ItemTemplate> 
         <asp:Button

刪除的UpdatePanel找到你自己的錯誤 - 更新面板隱藏JavaScript中的錯誤引發您只能查看如果您打開JavaScript控制檯 – Aristos

感謝您的答覆。我嘗試刪除UpdatePanel，但按鈕仍然不會將DetailsView放入編輯或新模式。沒有錯誤信息，只有模式不會像按鈕沒有做任何事情那樣改變。我不知道Java所以JavaScript不會幫助我。你能告訴我我錯過了什麼額外的編碼嗎？謝謝。 –

嘗試添加OnItemCommand事件處理程序到您的DetailsView。

<asp:DetailsView 
     ID="DetailsViewParentsDetails" 
     OnItemCommand="DetailsViewParentsDetails_ItemCommand" 
     runat="server" 
     Height="50px" 
     Width="404px" 
     AutoGenerateRows="False">

在您的代碼隱藏文件（的.cs），你將需要添加以下內容：

protected void DetailsViewParentsDetails_ItemCommand(object sender, DetailsViewCommandEventArgs e) 
{ 
    if (e.CommandName.Equals("New")) 
    { 
     this.DetailsViewParentsDetails.ChangeMode(DetailsViewMode.Insert); 
     this.DetailsViewParentsDetails.DataBind(); 
    } 
    else if (e.CommandName.Equals("Edit")) 
    { 
     this.DetailsViewParentsDetails.ChangeMode(DetailsViewMode.Edit); 
     this.DetailsViewParentsDetails.DataBind(); 
    } 
}
