I'm building a hierarchial grid using the self reference setting and everything seems to work as I want.  Using the dataloading event, I define the columns and grid properties.  A good example would be an org chart with n levels of employees.  Only the top level employees are displayed and any of them that have direct reports it will show the + to allow you to drill down (I have a filterdescriptor that filters out sub-employees so they are only visible as child records).  My issue is how to implement a Find function.  I have tried to bind the SelectedItem of each grid to a SelectedEmployee notify property.  If I do a find on a top-level employee, it works fine, but if it's a employee in a child grid, it doesn't work (I bound the child grids as (sender as GridViewDataControl).SelectedItem = new Binding("SelectedEmployee")).  If you can help with this, that would be great.  I also will need to auto expand all levels above this in order to display it after the fine.

Any help would be appreciated.

Hello Troy,

Generally, the items in the child grids will be loaded once they are expanded. Before that the grid is unaware that they exist, i.e. you cannot find any of the child items until the corresponding grid is visualized. 
If you want the described above functionality, you will need to implement the whole logic on your data level and you will need to have all the items loaded. Once you run through all those items and find the one you want in a child collection, you can find the corresponding data item and expand its row.
However, the exact implementation depends entirely on your specific settings and architecture.
