FileUpload.HasFile() always null
本文关键字:always null HasFile FileUpload | 更新日期: 2023-09-27 18:27:34
这是我在UpdatePanel中使用的代码。
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>
您是否尝试过将文件上传到更新面板之外?我以前也遇到过这个问题。
我有这个工作,尝试一下,让我知道。
