I've had good luck in the past simply adding a blank row to the data source and then checking for non-null values when the datagrid is updated. The user can just click in the empty row and add the information and the update routine can insert the values from there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
