AsyncFileUpload control start uploading file as soon as user select file. But normal behavior is, first user browse file then click submit button then file uploading should start. How to achieve this functionality in case of AsyncFileUploadf control?
The whole point of the AsyncFileUpload is that it uploads the file(s) asynchronously. Allowing the user to select other files while the control continues to upload the files already selected.
If you want browse for file, then submit file functionality, then you should use the standard FileUpload control.
To achieve this you need to download the source, and modify the AsyncFileUpload tool's source code.

I want to add a button and text box. When the user clicks on button the browse dialog gets open, after selecting the file the full path should be written to the text box.
And in second scenario when clicked on the button i should be able to select the folder not the file.
I tried with FileUpload,
1. I am not able to get the full path from the control
2. And not able to select a folder
and same with Html file control.
I am working on ASP.NET with VB.
Please suggest.
For security reasons, there's no way to retrieve the file path on the client side. Forget about that.

Problem i am facing:
When i click on submit button as page load event is called before buttons on click event value of file upload control is getting nulll.
could you please tell me how can i fetch the file upload control value after postback.
thanks is advance.
The file upload control does not retain the posted file with each request.
When the user selects a file, it will be available in the next PostBack request that occurs.
You should check for a PostedFile on each postback and save this file on the server.
Keep a reference to its path in the ViewState.
Then you can process the file when the user has finished all inputs.
I have a Master page with a script manager. I have a content page with an update panel. Inside the update panel i have several User controls which initially are all visible=false. After Opening one of the User control, i have not been able to attach my js file using
RegisterClientScriptInclude. I have used:
ScriptManager.RegisterClientScriptInclude(Page, this.GetType(), "key5", ResolveClientUrl("~/js/configurator.js"));
on the master page, on the content page and in the user control code behind. none of which shows that the js file is being loaded. i have always been able to do this but all controls have been visible from begining.
Could someone point how to load the script so that it is available for the User Control?
All I had to do is create a javascript handler like this so that it could be pick up after visible=true. $("button").live("click", function(e){......});
I want to be able to select multiple files when I click browse on the FileUpload browse button. I have it now to where I can choose one file and add it as a list using a jQuery but would I would like is to select multiple files to be added when I click open. Is there a simple way of doing this and is there maybe some kind of Javascript that might be able to handle this event?

I would like to display the size of the file that was chosen via the Browse button of the FileUpload control.
Ideally, this value is displayed immediately after the user chooses the file but BEFORE the "Upload File" Button is clicked.
I have and on a webform. The Button looks like this:
<asp:Button ID="UploadButton" runat="server" onclick="UploadButton_Click" Text="Upload File"/>
The onclick event for the button control results in a postback and the file is uploaded.
I know how to get the size of the file but not before the Upload File button is clicked and a postback occurs.
Is there an event associated with the FileUpload web control that could submit the form (i.e. postback) without the clicking of the button?
The whole intent is that I want to give the user a feel for how long the upload might take...set a different expection for a 10mb file than for a 2kb file, etc.).
The problem is that there's no way to find out the size of file on the client side without posting back. You could use Ajax, but that would mean uploading the file first anyway.
This can only be done using an ActiveX control of some kind. I would recommend using something like the Silverlight FileUploader because it gets the size of the file before posting back and even has a nice progress indicator.
UPDATE: If you want to trigger a postback or Ajax Request after the user clicks browse, the client side event is "onchange". Here's an example of how to use the onchange event.
<asp:FileUpload runat="server"
onchange="alert('you selected the file: '+ this.value)" />
You could have the onchange, trigger an ajax to upload the file first and then update a label showing the size of the file. The problem with this is that if it is a large file, it defeats the purpose of letting the user know before hand that it will take a long time.
Here's another recommendation: There's a jQuery plugin that uses flash to determine the size of the file before uploading and it's very easy to use. Check it out at jQuery Uploadify
