Web Forms :: FileUpload Control Don't Work On First Submission?

Feb 13, 2011

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.

Mobiles :: How Does Fileupload Control Work In Website For Blackberry

Mar 10, 2011

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.

Web Forms :: Form Email Data Submission By User Submission

Jan 15, 2010

I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.

I 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.

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.

FileUpload Doesn't Work When Nested In UpdatePanel?

Jan 21, 2010

<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.

AJAX :: FileUpload Controls Does Not Work Inside An Updatepanel

Feb 26, 2010

I 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 ?

AJAX :: Fileupload In Updatepanel With Timer Doesn't Work At The Second Time

Jan 23, 2011

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.

Web Forms :: Set The Current Value Of A FileUpload Control?

May 21, 2010

I have a 2 FileUpload controls.

Once the user selects a file in the first control, I want to set the default value for the 2nd control to be the value from the first control.

For example, if it were textbox controls I would just use TextBox1.text = TextBox2.text.

How do I do this for FileUpload controls? I tried a few different properties, such as FileUpload1.FileName = FileUpload2.FileName but I get an error saying that they are Read Only.

Web Forms :: Hide FileUpload Control?

May 7, 2010

I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.
