ItemDataBound在刪除命令上調用兩次

Question

我遇到了列表視圖問題。

Im做，當單擊在ListView刪除按鈕：（代碼簡化，它刪除，因爲它應該）

Protected Sub rlvCarts_ItemCommand(sender As Object, e As RadListViewCommandEventArgs) 
     If e.CommandName = RadListView.DeleteCommandName Then 
          mylistItem.items.RemoveAt(e.CommandArgument.ToString)      
      BindData()    
     End If 
End Sub 

Protected Sub BindData() 
    rlvCarts.DataSource = mylistItem.items 
    rlvCarts.DataBind() 
End Sub 

deleteting它將執行的ItemDataBound兩次當問題涉及（但列表視圖預渲染一次）。

它是怎麼來的？我怎樣才能避免這種情況？

解決：我不得不添加e.Canceled = True

Protected Sub rlvCarts_ItemCommand(sender As Object, e As RadListViewCommandEventArgs) 
     If e.CommandName = RadListView.DeleteCommandName Then 
          mylistItem.items.RemoveAt(e.CommandArgument.ToString) 
      e.Canceled = True  
      BindData()    
     End If 
End Sub 

它可以防止「自動重新綁定」當命令被稱爲
