I have a simple DGV using as a datasource a BBS connected to a childbo. Relationships all setup properly. Parent filters children. All data is loaded in parentform loading.



Starting with empty data in all tables.



I have tried setting Setdirtyonedit of the childbo instance to false and to true.



I can create a new parent, but on entering any grid I get the following error.



I know I'm missing something very basic here but as I have a dozen of these grids on my form this is a showstopper.



Would really appreciate any suggestions as to what I should be looking at and just what the tricks are to getting a datagridview and a bbs to play nice. For some reason I thought I had this all working and it does seem to not error if the parent isn't new, but on a new parent - BOOM



InvalidOperationException

Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.
