DataTable

I am working with GridView in asp.net 3.5,i want to display the columns(Hotelimage,Address,URL)in my grid. For this i wrote the following code in my grdvHotels.aspx.cs file.

Page_Load
{
   grdvHotels.DataBind();
}
DataTable GetData()
{
          DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("Hotel", typeof(string)));
            dt.Columns.Add(new DataColumn("Address", typeof(string)));
            dt.Columns.Add(new DataColumn("URL", typeof(string)));
 
          DataRow dr = dt.NewRow();
            dr["Hotel"] = ResolveUrl("~/IMAGES/image1.jpg");
            dr["Address"] = "Bangalore";
            dr["URL"] = ResolveUrl("www.yahoo.com");
            dt.Rows.Add(dr);
}
