Hierarchy Grid

[Ben]

I''m using a Grid data bound grid and gridhierarchylevel for displaying a Master-Detail. I want to access the row index of the current/selected row in the detail table. What method or properties should I be using to do this. I tried to use CurrencyManager but the datasource for the Grid is the Master table. I''ve looked at the sample for GridHierarchyLevel and didn''t see any clues.

I''m using 1.6.1.8

Thanks

You can get the GridBoundRecordState for the row.

int rowIndex = grid.CurrentCell.RowIndex;
GridBoundRecordState rs = grid.Binder.GetRecordStateAtRowIndex(rowIndex);

rs.Position will have the position of this record in its table.

> rs.Position will have the position of this record in its table.

I don''t believe that is correct, it was not my experience in practice unless I misunderstood or had a different expectation.
rs.Position returns the position value for the record relative to it''s siblings, and is zero based. So it might be position 0, the first child of the parent even though there are other parents with children.
To obtain the current record use
rs.ListManager.Current.

On another note, I have realized I was mistaken in my assumption of how GridHierarchyLevel behaved. If I''m in a GridDataBoundGrid with Master-Detail implemented how can I determine if the current row is a Master or Detail row.

Thanks for the support.

I am not sure what you mean by a Master-Details in a GridDataBoundGrid. Are you adding a parent-child relation to the dataset, and showing this in a hierarchical grid?

If so, try

int rowIndex = grid.CurrentCell.RowIndex;
GridBoundRecordState rs = grid.Binder.GetRecordStateAtRowIndex(rowIndex);

rs.LevelIndex will have the hierarchy level of the row.

Clay,

Sorry about the confusion, yes I''m using Master-Detail as parent-child relation to a dataset.

Ok, thanks this works. I thought I accessed the hierarchy level from the GridHierarchyLevel but need to use GridBoundRecordState. The documentation in 1.6.1.8 for GridBoundRecordState isn''t very complete, just hoping that it may have been improved for 2.0
