View 2 RepliesI use a tabcontrol with 2 tabs. In the second tabpanel as seen in the code I use a Fileuploadcontrol to upload Images from a users computer.
The problem is that I need to surround the tabcontrol with an updatepanel as I dont want a fullpage postback when switching between these 2 tabpanels. In this code I have the tabcontrol inside an updatepanel but the problem is that the Fileupload controls does not seem to work inside an updatepanel.
How will I solve this problem as I dont want a fullpage postback when switching between the tabs ?

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

I have a FileUpload Control on the page with validation and it is working smoothly.
Later there is an important demand to have it partially updated so we enclose it with UpdatePanel.
Then problem comes up when user browse file and press upload button, no file is uploaded.
Is it we cannot do partial rendering with FileUploader ?
I've got a plain C# web page that uses jQuery to call a handler page using AJAX. While the handler content is loading, a message "Please Wait, loading..." is displayed. Once I've got the content back from the handler I hide the loading message and display the content.What I'd like to do is after the loading message, display a percentage of how far through the handler page is. All the handler page does is loop through a list of members, powered by a web service, and adds them to the database so I know exactly how many members are being added to the database so I can tell how far I am through.The problem I'm having is because all of this goes on in a handler, how can I send the progress percentage back to the main web page while the handler was still loading.Any ideas? If I could do the exact same task but differently which would allow me to create the progress bar,
View 2 RepliesI'm trying to make a progress bar that updates the user on the progress of the AJAX call.
My immediate thinking was that I need an AJAX call to start a thread on the server, allowing the starting AJAX call to finish, and allowing the thread to send updates back to the user.
For the purpose of simplicity, disregard the actual progress bar functionality (I was thinking of implementing one of those JS bars, with fancy colors and effects ;), but if I can get an update from the thread, then updating a simple JS progress bar becomes trivial ;) )
I have a wierd issue with the update progress control in ie8. I have a modal popup that loads a pdf in an iframe, then i have a button click that navigates away from the pdf and shows a form in the same modal. All this is wrapped in an update panel, which i have an update progress control associated with. The control shows correctly in ie7, firefox, safari, and chrome. But in ie8 when the async post back is complete the progress indicator does not hide, until I click on the screen or scroll the page, then it hides and the form shows.

View 1 Repliesi have a problem with the fileupload, does not save anything
View 3 RepliesI have a fileupload in my ASP.net as well as other fields, of which some are mandatory.
If I populate the fileupload with a file and press save, because some of the mandatory fields are missing I stop the save and show an error message. However when the screen refreshes ansd shows the error message I loose the file in fileupload. Is there a way of retaining this?
I can't use JavaScript, restriction placed on by who I work for.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:FileUpload onchange="clickTheButton();" ID="FileUpload1" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
Button 1 is outside the update panel and the javascript that gets run when a user adds a file in the upload box is this:
function clickTheButton() {
document.getElementById('<%= Button1.ClientID %>').click();
}
The problem is simple. FileUpload1.HasFile == false. I don't know why this is, but when I put it in the update panel it ceases to work.
I have seen some other threads on this. But none of them answer why this is happening, they just point to things you can download.
EDIT: Really my main reason for wanting to do this is so that I can get a ..Uploading File.. Tag to pop up while the client is uploading to the server and once it has completed, display it in a datalist. I just cant get the UpdateProgress to work.
I'm having a problem with the FileUpload control in ASP.NET. It requires two postbacks to server in order to upload the file. In other words, after I select the file and click upload the page reloads but do nothing. Then I reselect the file and click upload then it works.
In my code I put a check for FileUpload.HasFile and it always fails (return false) on the first postback.
I tried to use the asp.net fileupload control for uploading a picture or music file, from blackberry device to server. But, What happened is ; the file is uploaded , ie, the file is created with 0 bytes in it. That is, file is actually not uploaded. Since blackberry browser doesn't support other fileformats, the device contains only .png & .m4a fileformats in its samples. I have used these sample in blackberry for uploading. The same has occured in the case of .m4a files also... Why is it so...? One more thing... The blackberry browser which I am refering here is the blackberry browser simulator, bold 9700.
View 7 RepliesI am uploading an image using the FileUpload control. After I have uploaded the Image to the server and the image is saved there, I am trying to show this image in an ImageBox like in the code.But the image is not shown in the Imagebox. I had this problem for some time but now wonder why the Image isn´t showing in the ImageBox. I have also tried to use the Page_Load event to track the SessionVariable to show the Image but this does not work ?(The file gets uploaded and saved to the specified path anyway, that part works)

I'm using a an Ifram that switches between several pages, each page contain a report viewer and takes time to load (about five seconds) since I'm using an Ifram the end user will not notice the loading of the page behind the seen (report pages) he will only notice a quick loading of the Ifram page ! so I tried to use the update panel and the update progress to show a waiting or loading progress image when the page loads or post back . but this doesn't work in Ajax since Ajax is not compatable with the report viewer .is there any way to show a progress waiting message during the page load using Javascript ?I Found many scripts like this that show a waiting message or image BUT the script starts after the page loads completely (a silly loop for 3 seconds maybe then hide the message )
