Question

在我上传文件的用户控件中，客户端（funClientUploadComplete，funClientUploadError）和服务器端事件（uplFile1_UploadedComplete）都没有被触发。经过一些调试，发现客户端事件函数是“未定义的”。它们在下面的HTML中明确定义。为什么他们仍然“未定义”？如何成功定义/绑定？我怀疑这也是没有调用服务器端事件函数的原因。请参阅下面的代码。感谢您的回复。

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<script type="text/javascript">
    function funClientUploadComplete() {
        alert('fdj-1');                            // alert box does not show
    }

    function funClientUploadError() {        
        alert('fdj-2');                            // alert box does not show    
    }

</script>

<div style="float: left;">
<asp:GridView ID="grdUploadControls" runat="server" AutoGenerateColumns="False" OnRowDataBound="grdUploadControls_RowDataBound" >
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:AsyncFileUpload ID="uplFile1" runat="server" OnUploadedComplete="uplFile1_UploadedComplete" OnClientUploadComplete="funClientUploadComplete"
                            OnClientUploadError="funClientUploadError" UploaderStyle="Modern" ClientIDMode="AutoID" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</div>

服务器端事件的代码隐藏:(断点未命中）

   protected void uplFile1_UploadedComplete(object sender, AsyncFileUploadEventArgs e)
    {
        // Typecast the source of this event to an AsynFileUpload
        AsyncFileUpload afux = (AsyncFileUpload)sender;
        .....
        .....
    }

谢谢你看看！
