    I have set the TargetFolder e.g. 


    and it works fine except that i want the file names to be kind od hashed e.g. myfile.jpg to be saved as 8unfsKjfjskskdjf^7i.jpg

    I have the HashFileName(string file) function but not quite sure where to apply it. 


    Thank you

    Hello Jugoslav,

    You could handle the FileUploaded server side event in order to process the file, change its name and save it manually to your server:
    protected void Unnamed_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
        // Get the file object
        var file = e.File;
        // Get file name and extension as string array
        var fileNameAndExtension = file.GetName().Split(new char[]{'.'});
        // Set a random string as file name
        fileNameAndExtension[0] = "RandomString";
        // Join new name with file extension
        var finalName = fileNameAndExtension[0] + "." + fileNameAndExtension[1];
        // Set pah to folder on server
        string path = Server.MapPath("~/Uploads/");
        // Save file with the new name in the given path
        file.SaveAs(path + finalName);
