任何想法，为什么 AjaxFileUpload1_UploadComplete 是无法读取的文本框的值

Any idea why AjaxFileUpload1_UploadComplete is not able to read text box value

我的CS code是：

My cs Code is:

    protected void AjaxFileUpload1_UploadComplete(object sender,     AjaxControlToolkit.AjaxFileUploadEventArgs e)
         {
   string c = System.IO.Path.GetFileName(e.FileName);
        string dpath = "~/Profile/Images/";
        string scn = txtSCN.Text;
        string line1 = txtLineitem.Text;
        string aging1 = txtAging.Text;             
        AjaxFileUpload1.SaveAs(MapPath(Path.Combine(dpath,c)));
        dpath = dpath + c;
        string str1 = ConfigurationManager.ConnectionStrings["ProTracConnGMCH"].ConnectionString;
        SqlConnection cn = new SqlConnection(str1);
        cn.Open();
        string sql = "Update tbNoquoteFollowupupdate set MailreceivedURL = '" + dpath + "', chkMailreceived = 1 , Buyername =  '" + buyername + "'  where scn = '" + scn + "' AND lineItem = '" + line1 + "' and Aging ='" + aging1 + "' ";
        SqlCommand cmd = new SqlCommand(sql, cn);
        int i = cmd.ExecuteNonQuery();

        if (i > 0)
        {
           // AjaxFileUpload1.SaveAs(Path.Combine(dpath, e.FileName));
            //AjaxFileUpload1.SaveAs(MapPath(dpath));
        }
        cn.Close();
        BindGridviewData1();
        cn.Open();
        string cmd2 = "Insert Into tbMulitmailsreived (scn, lineItem,followupdate, Aging,MailreceivedURL) Values ('" + scn + "', '" + line1 + "','" + DateTime.Now + "','" + aging1 + "','" + dpath + "')";
        SqlCommand sqlCommand2 = new SqlCommand(cmd2, cn);
        sqlCommand2.ExecuteNonQuery();
        cn.Close();
    }

请帮我

推荐答案

我花了一些时间，上周调查这个<一href="http://stackoverflow.com/questions/21752542/cant-get-text-from-textbox-in-method-for-ajaxfileupload1-uploadcomplete">question但到底能不能找到这样的一个简单的解决方案。在这个问题的任择议定书解决它通过存储在Session值，但这个工作，你仍然需要进行回传在某个阶段。

I spent some time last week investigating this question but in the end couldn't find an easy solution for this. The OP in that question solved it by storing values in the Session but for this to work you would still need to cause a postback at some stage.

目前显然是功能计划在AjaxFileUpload控制的背景下键集合传递值，但这是从来没有的实施。该<一href="http://stackoverflow.com/questions/13080186/how-can-i-use-the-contextkeys-property-for-the-ajaxfileupload-control">question介绍如何，虽然自己实现。

There apparently was functionality planned for the AjaxFileUpload control to pass values in the Context Keys collections but this was never implemented. This question describes how to implement this yourself though.

我的认为的我看到了另一个问题，围绕同一主题和OP通过改变使用<一个解决它href="http://www.asp.net/AjaxLibrary/AjaxControlToolkitSampleSite/AsyncFileUpload/AsyncFileUpload.aspx"相对=nofollow> AsyncFileUpload 控制，但我坚持要纠正...

I think I saw another question around the same topic and the OP solved it by changing to using the AsyncFileUpload control but I stand to be corrected...
