I'm looking to include a grid control that has features similar to the email view in Microsoft Outlook. We have customized the Grid and FlexGrid control in previous applications to meet these needs, but additional functionality is now required. Some of the features that are requested are:

  1. Expandable/Collapsable Rows based on a title row (similar to an outline)
  2. Editable cells
  3. Ability to include icons/images
  4. Sorting by columns


I've successfully implemented many of these features on top of a FlexGrid, but the overall effect is not satisfactory. Before we write our own control, I was hoping that someone would recommend a 3rd party control that would meet our needs.

Thank you in advance for any replies...
