Hello All,
I'm trying to discover the best way to handle the situation where you have a
datagrid in your app and someone changes a cell but doesn't leave that cell
(so there's the little pencil icon on the left margin of the datagrid) and
then the user clicks a menu to save the data in the datagrid. You see, my
problem is that at this point, the table attached to the datagrid hasn't
been updated because the user never left the cell they changed of the
datagrid. Is there a way to update the table attached to the datasource when
the datagrid looses focus? Maybe switching rows in the datagrid when it
looses focus would make the datagrid update to the table?
Thanks for any input...

Cheers :)
 
Hello Randy,

The following has worked for me:

1. Call EndEdit() on the grid.
2. Obtain a CurrencyManager instance for the grid through the form's
BindingContext property and call EndCurrentEdit() on that instance.

Step 2 ensures the row state in the bound table will be set to
added/modified, as the step 1 only pushes the data but does not update the
row state.
 
Thanks Dmitriy, works like a charm...
