I am not sure what I am doing wrong here and am hoping it is something simple I am overlooking!  I have seen this situation before, but was able to get it working with using bindingsource.endedit().  I have a 2 level dataset with parent-child relationship.  In my single-band grid, I have a button on each parent row, with which a user will click to add/edit the child rows.  The problem I am having is on adding a new parent row, and then clicking the button, that new parent row is not yet in the dataset - causing an error in trying to add the child row since it cannot find the key it wants for the parent row.  I have tried row.update, bindingsource.endedit, grid.updatedata....nothing seems to push this data to the dataset.  I also tried some performaction calls for commit row, exiteditmode, etc.  I can provide more information on how i edit for the child rows, if needed. 

 Thanks in advance for any input,

Dusty
