Listviewの更新コマンドを機能させることができないようです。これが私のデータグリッドです：

と私のItemCommandイベント：
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();
}
}
そして私もItemUpdatingイベントを試しています：
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();
そして最後に、私のバインディング方法：
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;
}
}
編集リンクをクリックすると、ListViewは本来のように編集モードになります。
の更新ボタンをクリックしても、イベントEditItemTemplateはトリガーされません。ItemCommand両方の作業を削除してキャンセルします。
ItemUpdatingイベントはまったく発生しません。
注：このListViewはSharePoint Webパーツ内のユーザーコントロールにあるため、ユーザーコントロールは動的に作成されます。私はそれがポストバックでグリッドをバインドすることに関係しているというこっそりの疑いを持っています。しかし、そうしないと、ページの最初のロードを除いて、リストビューが表示されません。
