            }))
            {
                StringBuilder htmlTable = new StringBuilder();

                var request = yt.Videos.List("snippet");
                request.Chart = VideosResource.ListRequest.ChartEnum.MostPopular;
                var response = request.Execute();
                var objResult = response.Items.ToList();
                if (objResult != null)
                {
                    htmlTable.Append("<table class='table table-bordered table-hover datatable-highlight' id='tbldata'>");
                    htmlTable.Append("<thead><tr><th>Category Id</th><th>Channel Id</th><th>Channel Title</th><th>Video Title</th><th>Description</th><th>Tags</th><th>Published</th></tr></thead>");
                    htmlTable.Append("<tbody>");
                    foreach (var colum in objResult)
                    {
                        htmlTable.Append("<tr>");

                        htmlTable.Append("<td >" + colum.Snippet.CategoryId + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.ChannelId + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.ChannelTitle + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.Title + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.Description + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.Tags + "</td>");
                        htmlTable.Append("<td >" + colum.Snippet.PublishedAt + "</td>");

                        htmlTable.Append("</tr>");
                    }
                    htmlTable.Append("</tbody>");
                    htmlTable.Append("</table>");
                    PlaceHolderTable.Controls.Add(new Literal { Text = htmlTable.ToString() });
                }
            }
