asyncfileupload

问题 I have code that does async file uploads which works fine on my dev vm but after I deployed it to the client system, I keep getting this error: "error writing mime multipart body part to output stream" I know this is the line that is throwing the error but I can't seem to figure out why: //Read the form data and return an async task. await Request.Content.ReadAsMultipartAsync(provider); The file size was only 1MB and I even tried different file types with much smaller sizes. Why would this

问题 Referring to the following: Ajax Asyncfileupload doesn't work as soon as I put it in a control I am having the same issue. I am not using a Master page though. I have an AsyncFileUpload control in a Panel, within an update panel. Any ideas as to what could be causing the issue? 回答1: When you use AsyncFileUpload you must set the right params in the form tag, that is placed in your Page or MasterPage: <form id="form1" runat="server" enctype="multipart/form-data" method="post"> If you don't set

问题 Using SWFUpload v2.2, Firefox 3, IE 8, Flash 10 In my ASP.NET application all uploads are being processed by upload.aspx (I have the correct upload_url set in the settings object). In IE 8 the uploads hit the upload.aspx page and are processed, but in Firefox they do not. Any suggestions?

问题 This is a strange one. So I have an Ajax Toolkit file uploader called AsyncFileUpload located in an update panel.

问题 How to add client side required validator to asyncfileupload ,to enforce user to select file before submitting the page. 回答1: You could also set the text of a the hidden textbox in a server side method using C# or VB, rather than a client side Javascript or JQuery function. protected void afu_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e) { afu.SaveAs(Server.MapPath("Uploads\\") + e.FileName); txt.Text = e.FileName; } 回答2: I use a RequiredFieldValidator that

问题 I am writting a client database system for my company. Not much fancy stuff, but it does what it should. Now that all the basic "text" stuff is done I want to add some filemanagement into it. I have several forms which get send to the backend with ajax and then written into the db in the model. Some of these forms are planned to have a document file upload. Is there a way to handle normal value submits and a file submit with AJAX ? Let me give you a FORM example: <form action="SOMEPATH/LOGIC

问题 I have an issue with multiple images upload to php server. The code given below works fine for android 2.x versions, but the same code doesn't work for android 4.x and above. I have googled and found out that the data posting has to be done asynchronously by AsyncTask. But I have no clue about how it has to be done via phonegap(calling of async task).
