DataGridView -Value does not gets saved if selection is not lost from a cell

Question

I am using the DataGridView Control for reading and writing an XML file through XML Serialization.

I have an issue as explained below:

1. I read an XML fi

Answer 1

I had the same situation and I was even using accelerator keys for save button for saving the grid values. When I click on Save button focus lost from DGV and hence cell value is committed, but when I use accelerator keys focus doesn't lost from DGV hence no committing of the cell value.

After looking at the Amit Karmakar answer out of curiosity I tried that answer and it worked. To find out more details I went into debugging of the DGV and found that it is really same thing as commitedit which somehow doesn't work if you use it in the save button click.

When we set CurrentCell of DGV to null, before setting it to null DGV first gets the edited value and pushes it in to cell value and then sets CurrentCell REFERENCE to null. Here it doesn't mean that it is setting underlying DGV cell to null. Hence this works perfectly for the above problem.

Note: This solution may not work perfectly when you have validating events for the cell and if user enters invalid data which will fail validation. In this case setting current cell to null also fails as it cannot push the value to cell.

I gave this explanation as I've raised question on Amit Karmakar answer asking how can it be possible. I thought it may help some other, so dropped this explanation as answer.
