无法获取AsyncFileUpload在更新面板工作 [英] Can't get AsyncFileUpload to work in update panel

问题描述

我有一个UpdatePanel中，脚本管理和控制asyncfileupload用户控件。

I have a user control with a updatepanel, script manager and a asyncfileupload control.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> 
<asp:ScriptManager ID="ScriptManager2" runat="server" ></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <cc1:AsyncFileUpload ID="AsyncFileUpload2" runat="server" />
        <asp:LinkButton id="lbSubmitOrder" runat="server" title="Submit Order Request" class="btn_blue_dynamic_med"/>
    </ContentTemplate>      
</asp:UpdatePanel>

在我的code背后：

 Dim path As String = Server.MapPath("~/temp/test.tmp")

 AsyncFileUpload2.SaveAs(path)

在我AsyncFileUpload2对象中的文件名是什么。我似乎无法得到refernce到应该是上传的文件。

In my AsyncFileUpload2 object the filename is nothing. I can't seem to get a refernce to the file that is supposed to be uploaded.

更新结果
我已经添加了

UPDATE
I've added

Private Sub AsyncFileUpload1_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles AsyncFileUpload1.UploadedComplete
    If e.state = AjaxControlToolkit.AsyncFileUploadState.Success Then
        '....'
    Else
        showErrorMessage(e)
    End If
End Sub

我不能在if语句创下了破发点，我选择一个文件之后。我想有什么不对我的网页上使用Ajax如何工作？不知道它是什么，但。

I can't hit a break point at the "if" statement after I choose a file. I guess there is something wrong on my page with how ajax is working? Not sure what it is though.

修复！结果
我是用一个可见=真/假格通过一个单选按钮显示了ajax上传框。答案告诉我，控件在那里加载页面。我带走了DIV和一切工作！我现在做节目/ jQuery的通过隐藏（我应该在第一时间做了）。

FIXED!
I was displaying the ajax upload box via a radio button with a visible=true/false div. The answer told me that the control has to be there the page loads. I took away the div and everything worked! I will now do the show/hide through jquery (which I should have done in the first place).

推荐答案

确认与asyncfileupload控制用户控件不通过的Response.Redirect（pageWithUploadControl）。

Make sure that the usercontrol with asyncfileupload control is not loaded asynchronously, for example via Response.Redirect("pageWithUploadControl").

你有没有处理的FileUploadComplete事件，并检查是否AsyncFileUploadState是成功？

Have you handled the FileUploadComplete Event and checked if AsyncFileUploadState is Success?

   Private Sub AsyncFileUpload1_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles AsyncFileUpload1.UploadedComplete
        If e.state = AjaxControlToolkit.AsyncFileUploadState.Success Then
            '....'
        Else
            showErrorMessage(e)
        End If
    End Sub

    Private Sub showErrorMessage(ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs)
        Dim message As String = String.Empty
        Select Case e.statusMessage
            Case AjaxControlToolkit.AsyncFileUpload.Constants.Errors.EmptyContentLength
                message = "Empty content length!"
            Case AjaxControlToolkit.AsyncFileUpload.Constants.Errors.FileNull
                message = "Fill NULL!"
            Case AjaxControlToolkit.AsyncFileUpload.Constants.Errors.InputStreamNull
                message = "Input Stream NULL!"
            Case AjaxControlToolkit.AsyncFileUpload.Constants.Errors.NoFileName
                message = "No File Name!"
            Case AjaxControlToolkit.AsyncFileUpload.Constants.Errors.NoFiles
                message = "No Files!"
        End Select
        LblMessage.Text = message 
    End Sub

尝试改变改变表单的ENCTYPE：

Try to change change the enctype of your form:

<form id="form1" enctype="multipart/form-data" runat="server">
