I want to achieve the following functionality for an XtraGrid. This is taken from Excel 2010 and is the action of Grouping from (Data -> Group Rows).
The solution I have so far is to use Master-Detail functionality of the XtraGrid, but I already use to "link" existing row to another row, creating a parent-child relation between them. Using the Master-Detail for the grouping displayed above would mix up the linking with the grouping. This could be ok but I want to somehow separate them visually.
To achieve the + and - signs and the vertical dark bar in the left I thought of adding an additional column in the Grid that contains either the imagine of a dark vertical line or a button.
Any help is much appreciated.

Thank you and have a good day.
