    Dear Support,

    I have created a custom class that inherits from FileBrowserContentProvider and have implemented all the neccesary methods.  I sometimes require to reject an uploaded file in the StoreFile method due to some business logic but was not able to figure how that could be implemented. Returning a non-empty string and throwing an exception did not work well. Since the class inherited from FileBrowserContentProvider has no access to the Page-derived class, I am not able to add an Error to the page. 

    Could you please help in directing me to a neat solution to my problem?

    Thanks in advance,

    Hello Omar,

    You can get reference to the page by using this code :

    public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments) 
        // The code that saves the file ; 
        string script = @"alert('MESSAGE');"
        Page page = HttpContext.Current.Handler as Page; 
        if (page != null
            page.ClientScript.RegisterStartupScript(page.GetType(), "ScriptKey", script, true); 
        return base.StoreFile(file, path, name, arguments); 

    Then you can add scripts to its script collection.

    I hope this helps.
