I have a File Explorer:

    
            <telerik:RadFileExplorer   
        
            ID="EquipmentFileExplorer"   
        
            runat="server"   
        
            InitialPath="~/AppData/Uploads/" 
        
            VisibleControls="TreeView, Grid, Toolbar, ContextMenus">  
        
            <Configuration   
        
            MaxUploadFileSize="2004800"   
        
            SearchPatterns="*.doc,*.pdf,*.gif,*.jpg,*.jpeg,*.tif,*.tiff"   
        
            DeletePaths="~/App_Data/Uploads/" 
        
            UploadPaths="~/App_Data/Uploads/" 
        
            ViewPaths="~/App_Data/Uploads/">  
        
            </Configuration> 
        
            </telerik:RadFileExplorer>

When I run the project, either locally or on a dev server, I receive an alert saying "Cannot Write To Target Folder". NETWORK SERVICE has modify set on the folder, so it should be ok?

I am using the latest ASP.NET release. Puzzled.

Hello Richard,

I am not quite sure what is causing this error in your case. I am wiling to help but this behavior probably is caused by the configuration of the server and it is not related to RadFileExplorer control. In your case I recommend you test this by using a regular asp:FileUpload control and upload a file to the same directory - ~/App_Data/Uploads/.

Best wishes,

Thank you for your reply.

I discovered the error was due to the uploader being contained within an update panel.

I've spun this functionality into its own page and all is well. I'd rather have the functionality within the look and feel of the master page but with this amount of functionality for so little effort that's splitting hairs a bit much :)

Regards,
Richard
