A couple of days ago I was working with a client who was having trouble using the File Upload Control from within a DotNetNuke module. I also uploaded a file using the FileUpload control, but the HasFile property returned false. Turn out that FileUpload.HasFile is also false if you upload an empty file. In this case adding some text to the file you want to upload will make the Hasfile property return true.
I have two forms for collecting user information. A quick form, and a long form. The quick form has a handfull of textboxes and a FileUpload control. The quickform is working perfectly. The long form on the other hand is built using a wizard control. On one of the steps I have another FileUpload control.
I had trouble at first because the FileUpload control was nested in the wizard and needed to use wizard1.findcontrol to find it. When I use the FileUpload control to browse to a file on the long form, the code FileUpload1.HasFile is always false, and skips processing.
Can you help find where I am going wrong? At what point in the wizard process are you checking for the file? I've never used an upload inside a wizard but my guess is that if the fileupload is in one of your middle steps and than you are trying to process the upload during a different step that the file will no longer be there. I'm pretty sure the fileupload is only valid for that first postback that the file is specified So if it's in a middle step you'll need to save it as a temporary file somewhere 'serialize into the session' or just somewhere temporarly on the drive than save it as an actual file when it's done. PureWeen, the wizard has 6 pages, with textboxes and drop downs throughout.
When the finish button is clicked I am able to work with all the values all at once from any page of the wizard. I do have viewstate enabled for the fileupload control, it is by default. Just as a test I moved the fileuploading code to the nextbutton click for the page it is on with the same result. Any other Ideas? Is my findcontrol code correct? The FileUpload control is nested as follows: UpdatePanel1:Wizard1:Step2:FileUpload1. Yea you'll be able to access all the other controls information because all of their information is serialized in the viewstate so they are accessible The difference with a fileupload control is that the file itself is NOT saved into the viewstate.
What happens with a fileupload control is that the content of the file gets sent up ONLY with the postback that the fileupload control was specified on and that's it. You have to save the file during that postback.
Here try this to demonstrate what I'm saying: Put a fileupload control on a blank page with a single button. Than click the button you'll notice on the postback the fileupload control becomes clear That's because the file was sent in that postback from the client system to the server and it's your job to save the file You have to save the file somewhere on the postback that occurs directly after specifying the file You can either serialize it into the session Or save it temporarly somewhere. Hi i am using 3.5 framework.
I have difficulties in the ajax upload as the fileupload.hasfile is always = false Please advice 6 7 And the Code that uses its reference is as follows string file = string.Empty; if (fleImage.HasFile) fleImage.SaveAs('./images/inventory/inventory' + newid); file = fleImage.PostedFile.FileName. I am new here, but have been searching for a while, and may not have the correct lingo to find what I am looking for. I am tasked with implementing a.exe application that was writen vb6 then converted to.net into a new website my team is developing. The idea is to put each of the 3 different forms in this.exe application of 3 different.aspx pages. I have attempted multiple things to get this into the page and even started to just rewrite it as an ASP.net web form, but even then I can't reuse any of the code since the System.Web.UI.Page doesn't inherit the sa. Hello,I got an interesting problem today.
When FileUpload control is placed in an UpdatePanel, HasFile property is always false. It is not only the HasFile property which is false but also other attributes like file name and length are set to blanks and zeros.If the FileUpload control is pulled out of UpdatePanel, the problem is solved. Can anyone please tell me how to make FileUpload controls to work with UpdatePanels? Cheers,Gopi Gopinath MDo you know your blog/web site page rank?
Check Google Page Rank Now The FileUpload control doesn't work with an asynchronous post. I've seen the posts on this but the solutions offered don't remedy my problem. I have an FileUpload in a user control.
I can get all the details from the user control (from textboxes); however, the FileUpload.HasFile always returns false. From searching the forums I saw that most problems have been due to using the FileUpload in an update panel. My FileUpload is not in an update panel. It was briefly but after reviewing other posts I took it out.
It seems as though the page still thinks it is in an update panel but I have removed all references. We are creating a database driven website as part of our project. Currently we have forms connecting to the database created in visual basic.
These windows forms we need to convert into web forms which are asp.net compatible. Can u give me an answer or show me a way. Hi, because of the difference in nature between web and win applications you'll need to reimplement at least the UI part. If you have a multitiered application in which the busines logic and data access are in different parts/assemblies you can reuse them. Grz, Kris.Read my blog.

Hi all I have written some test web services and some web form applications and deployed them to my IIS. That's fine but I now want to deploy them to my real IIS server. I have created an msi for each but the problem is I seem to only be able to deploy to the default web site. Our default web site is turned off and instead we use several other sites. Does anybody happen to if Powerbuilder 11 supports non default web sites? If not do I need to hack the msi and if so can anybody suggest a suitable tool. I have Orca but it's not very friendly.
Unless of course I knew exactly w. Hey everyone, I am looking to develope a web site that depending on the device connecting to it, it will display a certain page. In this case im looking to create a web and wap version of the same project. I have the Web forms version finished using ASP.NET and C# and I am wondering how to create the mobile web form and incorporate it in the project. In the project folder, can I just add a mobile web??? But what about displaying device specific pages?? Cheers -Dudach Yes, you can add mobile web forms and controls to your Web Application project.
For device/br. In putting together an ASP.NET application for a biz application, we have come to the point where there are three different types of basic forms which have, for the most part, been perfected. Now its is a matter of cloning those forms for various uses and modifying or adding code to suit the particular need. Copy and paste works OK, but there is a lot of changing of certain words, etc. Is there a way in ASP.NET to take these basic forms, turn them into classes or templates, create forms from them, then add or overwrite code?? (Anybody who is a Vis Fox Pro programmer would know imme.
Web Form Resized by position of the div: if div can't dispaly all (such as only top part, then web form heithten the heght),resize the web form! Because of my pool English, if you can't see, I will explain more! ThanksGambler is the real life I guess you mean when form grows it also grow parent div element. This is normal. If you want div to stay fixed size and rather clip the form and maybe show a scrollbar, look at overflow property in CSS.Thanks-This posting is provided 'AS IS' with no warranties, and confers no.
If you don't mind, I would like to know what is the difference between those two items, when I go to add a new item I see both of those and I don't know what the difference is. A content form is for use with a masterpage. A web form is a standalone web page. If you select web content form, you will then have to specify a masterpage for it. And what is a master page used for?
Hi, a master page is used to give a constant look and theme to a site, without having to duplicate code. So basically you can put your header, menu, nav and footer on a master page.
I try to upload file inside AspxGridView EditItemTemplate. I've found this article. My aspx page looks like this Upload but file comes in postback only from the SECOND TRY.
I press 'edit' in row 2. Select some file.
Press 'upload' button 4. In the lbUploadClick fuImage doesn't contain file 5. Select file once more 6.
Press upload 7. FuImage contains file. Repeat steps 5-7.
Revisit page. And everything repeats.
