    In my Custom ContentProvider, is there a way to return an error string from StoreFile()?

    Hi Chris,

    The StoreFile function returns the path to the stored item and we do not recommend you replace that behavior. Could you please provide more details on what exactly you want to achieve?

    I also have a need for this. We are using the custom file provider example to allow people to have access to their home directory when they are not on site. However, they have a limited amount of space. When they hit their space limit, I'd like to report a nice message instead of it just throwing an exception. The exception that is being caused when they run out of space is: There is not enough space on the disk.

    Hi guys,

    To achieve the required functionality you can override the StoreFile() method of the content provider, handle the exception and use the ScriptManager.RegisterStartupScript() to display an alert with the custom message. You can get reference to the Page object from the content provider using the following code:
    var page = HttpContext.Current.Handler as Page;

    The following is a sample StoreFile() method that pop-ups an alert:
    public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)
            throw new IOException("Forced Exception");
        catch (IOException e)
            var page = HttpContext.Current.Handler as Page;
            ScriptManager.RegisterStartupScript(page, page.GetType(), "key", @"alert(""Custom Error Message!"");", true);
        return base.StoreFile(file, path, name, arguments);

    I hope this helps.
