Question

这是我用于UpdatePanel的代码。

FileUploadAsync.HasFile（）始终为null。

我想知道我的asp.net页面出了什么问题......

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="Server" />
<asp:UpdatePanel ID="UpdatePanelAddFiles" runat="server" UpdateMode="Conditional">
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="LkUpload" />
    </Triggers>
    <ContentTemplate>
    <asp:LinkButton ID="LkUpload" runat="server" OnClick="LkUpload_Click" Visible="false">Upload</asp:LinkButton>
        <ajaxToolkit:AsyncFileUpload runat="server" ID="FileUploadAsync" />
    </ContentTemplate>
</asp:UpdatePanel>

您是否尝试过更新面板外的文件上传？我之前遇到过这个问题。

我让这个工作，尝试一下让我知道。

    <asp:UpdatePanel ID="upTest" runat="server">
        <ContentTemplate>
            <ajaxToolkit:AsyncFileUpload ID="AsyncFileUpload1" runat="server" 
                onuploadedcomplete="AsyncFileUpload1_UploadedComplete" />
        </ContentTemplate>
    </asp:UpdatePanel>

    </div>
    </form>
</body>
</html>

代码隐藏：

    protected void AsyncFileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
    {
        if (AsyncFileUpload1.HasFile)
        {
            //do save process here
        }
    }

FileUpload.HasFile（）始终为null
