Empty datagrid in ASP.NET

Question

I dont understand. I am using this collection object to fill the data from database. I am using this colleciton object and constructing a datatable and later i am binding this datatable to the datagrid, but to my dismay, its not showing anything on screen. Well, when i debug i can see the data, but some how, the datagrid is not taking data from the datatable here is the sample code private void Page_Load(object sender, System.EventArgs e) { //Set Today's date and time information lblDate.Text=DateTime.Now.ToShortDateString().ToString() + " " + DateTime.Now.ToShortTimeString().ToString(); //DataGrid dgMainTopic=new DataGrid(); if(!IsPostBack) { //Populate the grid with the data for maintopics DataTable dgTable= PopulateMainTopicGrid(); dgMainTopic.DataSource=dgTable; dgMainTopic.DataBind(); } } private DataTable PopulateMainTopicGrid() { try { MBoard.MainTopicService.MainTopicsService MTService=new MBoard.MainTopicService.MainTopicsService(); MBoard.BoardCollection GridCollection=new MBoard.BoardCollection(); MBoard.MainTopicInfo.MainTopicInfo MTInfo=new MBoard.MainTopicInfo.MainTopicInfo(); GridCollection=MTService.getAllMainTopics(); DataTable dtMTopic=new DataTable(); DataRow drTopicRow; DataColumn drTopicCol; //Add all the column headers //Forum Topics Messages LastPost drTopicCol=new DataColumn(); drTopicCol.Caption="Forums"; drTopicCol.ColumnName="Forums"; dtMTopic.Columns.Add(drTopicCol); drTopicCol=new DataColumn(); drTopicCol.Caption="Topics"; drTopicCol.ColumnName="Topics"; dtMTopic.Columns.Add(drTopicCol); drTopicCol=new DataColumn(); drTopicCol.Caption="Messages"; drTopicCol.ColumnName="Messages"; dtMTopic.Columns.Add(drTopicCol); drTopicCol=new DataColumn(); drTopicCol.Caption="LastPost"; drTopicCol.ColumnName="LastPost"; dtMTopic.Columns.Add(drTopicCol); //Add all the rows(Data from the database) for(int i=0;i
