javascript - 泰勒瑞克 : preventing postback with RadButton confirm dialog

Question

我在执行确认对话框时遇到问题，要求用户确认他的删除选择。如果用户单击取消，RadButton 不应回传到服务器。确认对话框从未显示，我做错了什么？

<script type="text/javascript">
    function confirmAspButton(button) {
        function aspButtonCallbackFn(arg) {
            if (arg) {
                __doPostBack(button.name, "");
            }
        }
        radconfirm("Are you sure you want to delete?", aspButtonCallbackFn, 330, 110, null, "Confirm");
    }
</script>


<telerik:RadButton
    ID="btnDeleteLines" 
    runat="server" 
    OnClientClicking="confirmAspButton(this); return false;"
    OnClick="btnDeleteLines_Click"
    Text="Delete line(s)"
    AutoPostBack="false"
    GroupName="GroupName1">
</telerik:RadButton>

好的，我找到了the telerik website上描述的方法, CustomRadWindowConfirm。

<script type="text/javascript">
    //Custom RadWindow Confirm
    function CustomRadWindowConfirm(sender, args)
    {
        //Open the window
        $find("<%= confirmWindow.ClientID %>").show();
        //Focus the Yes button
        $find("<%= btnYes.ClientID %>").focus();
        //Cancel the postback
        args.set_cancel(true);
    }
    function YesOrNoClicked(sender, args)
    {
        var oWnd = $find("<%= confirmWindow.ClientID %>");
        oWnd.close();
        if (sender.get_text() == "Yes")
        {
            $find("<%= btnDeleteLines.ClientID %>").click();
        }
    }
</script>


<telerik:RadButton
    ID="btnDeleteLines" 
    runat="server" 
    OnClientClicking="CustomRadWindowConfirm"
    OnClick="btnDeleteLines_Click"
    Text="Delete line(s)"
    AutoPostBack="false"
    GroupName="GroupName1">
</telerik:RadButton>
