Looking for a DataGridView that allows grouping

Basically I'm looking for a control that allows for grouping in a DataGridView control that can also be editted (I.E. somthing like DataGridView and TreeView into a single control).

Thanks in advance.

From stackoverflow

• DevExpress has a great control that is a tree/gridview with grouping.

  Demo here.

  Index of some ASP.Net controls can be found here.

  : Anything free controls?

  achinda99 : No good ones that I know of. You can do a combination of Trees and Gridviews but its ugly and complicated.

• Infragistics UltraWebGrid (ASP.NET) and UltraWinGrid (Windows Forms) support grouping and can be setup as edittable grids. These controls are part of their NetAdvantage Suite.

• Herre Kuijpers made a OutlookGrid in CodeProject, which derives from DataGridView, and allows grouping of rows.
