I would like to know if its possible to upload files in RadAsyncUpload control from codebehind.
Instead of pressing "Select" button of RadAsyncUpload control and selecting files and uploading it, I would like to upload a list of files present in a directory into RadAsyncUpload control from codebehind.
If we can upload files from code behind, is it possible for you to show me a demo.
Please note, i have RadAsyncUpload control as a usercontrol registered in a page.
Thanks.
The upload process through the codebehind is not allowed.
RadAsyncUpload is based on the HTML input type=file element, which allows to upload files only from the client's machine. The user is allowed to select a file from his/her machine and upload it through the select file dialog of the input element.

You need to use Url.Encode to create URL
Click Here to download the file
I use WebBrower of microsoft to log into a website. I have no problem with logging in. I don't have the downloadable file url because the file is generated automatically.
How should I download file with out Save As popup to show ?
Work with the DOM (document object model) of the website find your download link via traversing the DOM exposed by the browser control via it's property
Document
it is a tree of elements that your after-login page consists of. There should be some element that you should invoke click on it and then handle OnNavigating (https://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.onnavigating(v=vs.110).aspx) event of the control to get the generated download URL.
I have a FileUpload control in my ASP page. Once I choose a file from disk it will display the full path C:\users\star\one.jpg on its textbox.
<asp:FileUpload ID="filUpload1" runat="server" />
Then I have done some validation clicking button. As result of that button click event it will occur page refresh. And it will clear that file path on control.
How Can I display FileUpload full path after page refresh?
I have tried ViewState ,However it dosn't allow me to store full path itself. Please help me.
This is not possible.
Asp.net uses html forms to send its data. Due to browser security constraints and user privacy issues, the full path is not sent to the server.
However on the next postback that occurs, the full file does get uploaded to the server.
Using the FileUpload control, the contents of the file are only available on the first postback after the user selected the file.
What you should do is save this file at that time, and make a note of it in the ViewState(Where you saved the file on the server).
When when final submit occurs, you can use the file that is already uploaded on your server.

I need some help, I have FileUpload control on my asp.net page and Image where I show image which is uploaded on server. What I want that Image show what I choose when I click on Browse in FileUpload control before I upload on server. How to achieve that ?
You will need to use some sort of Flash/Silverlight/Java control that can access the file system and show a thumbnail of the selected file. What you want is not possible otherwise, without uploading the file to the server first.
I think you must upload file to server asynch. before saving by user.
hai friends
I am using a file upload control to upload the files if the user browse and upload the file. after uploading the path gets disappears. i should be maintain there itself. how?
Well, this is the default behavior of the browsers for security reasons
have a look at MS support site for IE http://support.microsoft.com/kb/266087
Edit
In your code behind you can try something like
fileUpload.Attributes.Add('value',filename);
see if this works.
