RadDatePicker SelectedDateChanged問題

Question

我有RadDatePicker控件與SelectedDateChanged事件。當我更改日期時，事件觸發與確認窗口。當我點擊'取消'按鈕RadDatePicker1_SelectedDateChanged再次調用並顯示確認窗口兩次。當我點擊「確定」按鈕時，它工作正常。可能是什麼問題呢？感謝您的任何建議。

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" AutoPostBack="true" OnSelectedDateChanged="RadDatePicker1_SelectedDateChanged" > 
         </telerik:RadDatePicker> 


protected void RadDatePicker1_SelectedDateChanged(object sender, EventArgs e) 
{ 
string radalertscript = "<script language='javascript'>function f(){ radconfirm('Are you sure?', confirmChange, 400, 100) ; Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>"; 
        Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert33", radalertscript); 
} 

這裏是JavaScript函數

function confirmChange(args) { 
    if (args) { 
     __doPostBack("<%= hiddenButton1.UniqueID %>", ""); 
    }

它，如果你只是用它來渲染一些JavaScript似乎是一個unnessary回發。

您可以在客戶端進行確認對話嗎？

<script type="text/javascript"> 
function ConfirmChange(sender, eventArgs) { 
    var date = eventArgs.get_renderDay().get_date(); 
    var dfi = sender.DateTimeFormatInfo; 
    var formattedDate = dfi.FormatDate(date, dfi.ShortDatePattern); 
    eventArgs.set_cancel(!confirm("Are you sure you want to " + 
    (eventArgs.get_isSelecting() ? "select " : "unselect ") + 
    formattedDate + "?")); 
} 
</script> 

<telerik:RadCalendar ID="RadCalendar1" runat="server"> 
    <ClientEvents OnDateSelecting="ConfirmChange" />
