Hi

  I am getting error - +        $exception    {"An invalid data source is being used for rptData. A valid data source must implement either IListSource or IEnumerable."}    System.ArgumentException

 public void GetChannelList()
    {
        YouTubeService yt = new YouTubeService(new BaseClientService.Initializer() { ApiKey = "AAAAAA" });

        var searchListRequest = yt.Search.List("snippet");
        searchListRequest.ChannelId = "as8AA1A";
        var Result = searchListRequest.Execute();
        if (Result != null)
        {
            rptData.DataSource = Result;
            rptData.DataBind();
        }
    }
