Hello,
We've started using the FileExplorer to manage files inside our company, what we usually need is simple uploading and downloading. What's the correct way to handle file downloads? Is it with the open method? Because in that case when for example i try to download an .xml file, the browser knows how to interpret the file and it's shown to me in a radwindow. What i want is for it to be downloaded to my computer, but i can't use the usual 'save target as' context menu item as i would usually do to download such a file. The only way we've found until now to handle such files is to zip them beforehand, but it's very inconvenient. Could you point me to a better way to handle this scenario?

Thank you

Hello Cristian,

The file download feature is not related to RadFileExplorer control.You need to implement your own code that will explicitly force the browser to download the files, instead of opening them for preview and this online demo shows the exact steps in order to achieve the desired result. In addition, I recommend you to check the "FORCE THE BROWSER TO DOWNLOAD THE FILES"  section of this KB article for more information on the subject. More details about MIME types can be found here.

I hope this helps.

Hello,
I've looked at your code samples, and i added a script file with the OnClientFileOpen and referenced it through the <head></head> tag of the page (the reason being that i'm using a sitefinity website, and the FileExplorer is inside a user control).
This is how i then modified the FileExplorer to look like:
<telerik:RadFileExplorer ID="FileExplorer" runat="server" Skin="Black" EnableOpenFile="true" OnClientFileOpen="OnClientFileOpen">
    <Configuration ViewPaths="~/Downloads/" MaxUploadFileSize="10000000" />
</telerik:RadFileExplorer>
The problem now is that the files are no longer shown. By deleting the OnClientFileOpen property the files are shown again. Any help would be appreciated.

Thank you

Hi Cristian,

Could you please enable script debugging and send us the JavaScript error if such one appears?

Note that you should add client-side handler too as it shown in the following online example.
"When a file is opened (double click on it), the extension of that file is checked inside the OnClientFileOpen event handler and in case that it is a 'jpg' or 'gif' file the event is canceled. The file is opened for direct download and not inside a preview window. The files are stored in a folder on the server and the downloaded file is served by the content-streamer - Handler.ashx file. Please note that the EnableFileOpen property needs to be set to "true" (it is "true" by default)."


All the best,
Petio Petkov

The online example you mention does not work with windows filename.
Is there some form of URLEncode you could recommend?

When I tried the method described in the sample code, I get the error message "The resource cannot be found" on the file Handler.ashx.

Is Handler.ashx built into the ASP.NET framework or Telerik framework?  Where I can add it?

The samples for this issue no longer come up on the server - an error displays. I really need this to resolve a client issue (forcing a download of xml). Thanks.

Hi Karl,

I have attached a project which shows how to force download for XML files.

Best wishes,
