Finding out what level the grid is in - based on ExpandGrid example

I''m working on a grid based off the ExpandGrid example. I have two levels, a master and a detail, related by hlBatch_Item = gridBinder.AddRelation("BatchItem"); I''ve added a context menu to the grid, which should behave differently if the user is clicking on an Item row or on a Batch row. - How can I find out in which one I am? - From a group of expanded Item rows, how can I obtain their corresponding Batch row? Thanks in advance, Ricardo

Given a particular grid rowIndex, you can use GridBoundRecordState rs = this.grid.Binder.GetRecordStateFromRowIndex(rowIndex); This GridBoundRecordState holds the information you requested, rs.LevelIndex and rs.Position. To get the rowIndex under the current mouse location, you can use code like; int row, col; Point pt = this.grid.PointToClient(Control.MousePosition); this.grid.PointToRowCol(pt, out row, out col, -1);

Thanks!
