What does your class look like? Maybe there is a cyclic reference in one of the properties?

hi
thanks for helping....




Code:
using System;
using System.Collections;

namespace bsm
{
   /// <summary>
   /// Summary description for Order.
   /// </summary>
   public class Unit
   {
      #region private internal members
   
   //   private int order_id;
   //   private string unitcode;
   //   private string unitname;


      #endregion
      
      #region public properties
      
      public int unit_id
      {
         get
         {
            return unit_id;
         }
         set
         {
            unit_id = value;
         }
      }

      
      public string unitcode
      {
         get
         {
            return unitcode;
         }
         set
         {
            unitcode = value;
         }
      }


      public string unitname

Code:
public string unitname
      {
         get
         {
            return unitname;
         }
         set
         {
            unitname = value;
         }
      }



think about what this means ...

When you call the property getter via myFoo.unitname it calls the property getter unitname which calls the property getter unitname ... etc.

Same for setter.

You have to back your property by some field.

E.g.

Code:
public int MyInt
{
    get
    {
        return m_myInt;
    }
    set
    {
        m_myInt = value;
    }
}

private int m_myInt;
