  Hi Meenakshi

  I found a solution around the bug
  
  simply i write overwrite extension for SelectedIndex Property and use SelectedIndexEx instead SelectedIndex.

  public partial class C1ComboBoxEx : C1ComboBox
  
  {
  
  public C1ComboBoxEx()
  
  {
  
  InitializeComponent();
  
  }

      protected override void OnPaint(PaintEventArgs pe)
      {
          base.OnPaint(pe);
      }
  
      private int _selectedIndexEx;
  
      public int SelectedIndexEx
      {
          get
          {
              return this._selectedIndexEx;
          }
          set
          {
              if (value < -1 || value >= this.Items.Count)
              {
                  throw new ArgumentOutOfRangeException();
              }
              if (this._selectedIndexEx != value)
              {
                  this._selectedIndexEx = value;
                  this.SelectedIndex = value;
              }
          }
      }
  }
  

  thanks !!!
