我似乎無法讓我的Listview更新命令工作。這是我的DataGrid：ItemCommand更新和ItemUpdating不能在ListView中工作

</asp:ListView>
和我ItemCommand事件：
protected void lvECOItems_ItemCommand(object sender, ListViewCommandEventArgs e)
{
Label ecoItemIDLabel = (Label)e.Item.FindControl("IDLabel");
string id = ecoItemIDLabel.Text;
// get the list item id from the ListView
if (!String.IsNullOrEmpty(this.ecoID) && !String.IsNullOrEmpty(id))
{
if (e.CommandName == "Delete")
{
ECOItemsRepository ecoItemsRepository = new ECOItemsRepository();
ECOItems ecoItems = new ECOItems();
ecoItems.ECOID = this.ecoID;
ecoItems.ID = Int32.Parse(id);
ecoItemsRepository.Delete(ecoItems);
}
else if (e.CommandName == "Update")
{
ECOItemsRepository ecoItemsRepository = new ECOItemsRepository();
ECOItems ecoItems = new ECOItems();
Label IDLabel = (Label)e.Item.FindControl("IDLabel");
TextBox txtDocumentNumber = (TextBox)e.Item.FindControl("txtDocumentNumber");
TextBox txttitle = (TextBox)e.Item.FindControl("txttitle");
TextBox txtRevisionFrom = (TextBox)e.Item.FindControl("txtRevisionFrom");
TextBox txtTo = (TextBox)e.Item.FindControl("txtTo");
ecoItems.ECOID = this.ecoID;
ecoItems.ID = Int32.Parse(IDLabel.Text);
ecoItems.DocumentNumber = txtDocumentNumber.Text;
ecoItems.title = txttitle.Text;
ecoItems.RevisionFrom = txtRevisionFrom.Text;
ecoItems.To = txtTo.Text;
ecoItemsRepository.Edit(ecoItems);
}
BindListView();
}
}
，我甚至嘗試ItemUpdating事件：
protected void lvECOItems_ItemUpdating(object sender, ListViewUpdateEventArgs e)
{
ECOItemsRepository ecoItemsRepository = new ECOItemsRepository();
ECOItems ecoItems = new ECOItems();
Label IDLabel = (Label)lvECOItems.EditItem.FindControl("IDLabel");
TextBox txtDocumentNumber = (TextBox)lvECOItems.EditItem.FindControl("txtDocumentNumber");
TextBox txttitle = (TextBox)lvECOItems.EditItem.FindControl("txttitle");
TextBox txtRevisionFrom = (TextBox)lvECOItems.EditItem.FindControl("txtRevisionFrom");
TextBox txtTo = (TextBox)lvECOItems.EditItem.FindControl("txtTo");
ecoItems.ECOID = this.ecoID;
ecoItems.ID = Int32.Parse(IDLabel.Text);
ecoItems.DocumentNumber = txtDocumentNumber.Text;
ecoItems.title = txttitle.Text;
ecoItems.RevisionFrom = txtRevisionFrom.Text;
ecoItems.To = txtTo.Text;
ecoItemsRepository.Edit(ecoItems);
this.lvECOItems.EditIndex = -1;
BindListView();
最後，我的裝訂方法：
protected void BindListView()
{
if (!String.IsNullOrEmpty(this.ecoID))
{
ECOItemsRepository ecoItemsRepository = new ECOItemsRepository();
this.lvECOItems.DataSource = ecoItemsRepository.GetECOItems(ecoID);
this.lvECOItems.DataBind();
this.lvECOItems.Enabled = true;
}
else
{
this.lvECOItems.Enabled = false;
}
}
當我點擊編輯鏈接時，ListView會進入編輯模式。
當我點擊EditItemTemplate中的更新按鈕時，它不會觸發ItemCommand事件。刪除和取消兩個工作。
ItemUpdating事件根本不會觸發。
注意：此ListView位於sharepoint webpart中的用戶控件中，因此用戶控件是動態創建的。我有一個偷偷摸摸的疑問，它與綁定網格的回發有關。但如果我不這樣做，listview不會填充，除非頁面的初始加載。
