  Problem getting a datagrid to display information.

  Dec 01, 2005 05:21 PM|sanjeet|LINK

  I have a datagrid called: dgRevCatDisplay. When the page loads no data gets displayed.
  
  I tried setting a breakpoint on the datagrid all the objects and methods that instantiate the datagrid seem to be ok.
  
  However in debug mode when I type the object name in the immediate window I get an error message that says object not in scope.
  
  I do have the datagrid instantiated in the class:
  
  protected System.Web.UI.WebControls.DataGrid dgRevCatDisplay.
  
  I put a this before the datagrid. Data does exist in the database.
  
  here is my code:
  
  ----------------------------------------------------
  OnlineCaseCategoryController occc = new OnlineCaseCategoryController();
  dgRevCatDisplay = new DataGrid();
  dgRevCatDisplay.DataSource = occc.List();
  dgRevCatDisplay.DataBind();
  occc = null;
  ----------------------------------------------------
  
  This is the object the populated the Datagrid:
  
  ---------------------------------------------
  public class OnlineCaseCategoryController
  {
  public ArrayList List()
  {
  ArrayList infoList = null;
  IDataReader idr = null;
  try
  {
  idr = DataProvider.Instance().ListOnlineCaseCategory();
  infoList = DotNetNuke.CBO.FillCollection(idr, typeof(OnlineCaseCategoryInfo));
  }
  finally
  {
  if (idr!=null)
  {
  idr.Close();
  idr.Dispose();
  idr = null;
  }
  }
  return infoList;
  }
  
  ----------------------------------------------------------------------
  This is where the OnlineCaseCategoryInfo is declared. It's constructors are:
  ---------------------------------------------------------------------
  
  infoList = DotNetNuke.CBO.FillCollection(idr, typeof(OnlineCaseCategoryInfo));
  
  
  
  
  public class LookupInfoBase
  {
  private int _id;
  string _description;
  
  #region public properties
  public int Id
  {
  get
  {
  return _id;
  }
  set
  {
  _id = value;
  }
  }
  
  public class OnlineCaseCategoryInfo : LookupInfoBase
  {
  // local property declarations
  int _categoryid;
  
  #region Constructors
  public OnlineCaseCategoryInfo()
  {
  }
  
  public OnlineCaseCategoryInfo(int categoryid, string description)
  {
  this.Categoryid = categoryid;
  this.Description = description;
  }

  What type of list is getting returned?  Does it interface IEnumerable?  Make sure the list is actually loading too.
