Re: dynamic dnnview

          HtmlTableRow tr = new HtmlTableRow();
          HtmlTableCell td = new HtmlTableCell();
         -> LabelControl lbl = new LabelControl();
          td.Controls.Add(lbl);
          tr.Controls.Add(td);

An error has occurred.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.UI.Utilities.DNNClientAPI.EnableMinMax(Control objButton, Control objContent, Int32 intModuleId, Boolean blnDefaultMin, String strMinIconLoc, String strMaxIconLoc, MinMaxPersistanceType ePersistanceType, Int32 intAnimationFrames) at DotNetNuke.UI.UserControls.LabelControl.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---
