Datarow not created when setting cell value

[Dranizz]

I want to set the value of a cell in a datagridview.

DatagridView.CurrentRow.Cells(CEllName).value = "Blabla"

When I do this in code and when it's the first cell I edit in a new row, it does not Bind to a new datarow.
DatagridView.CurrentRow.DataBoundItem is nothing
A new row is added only if I type (keyboard) anything in the cell, but programmatically, it does not add the row.

How can I tell the datagridview, in code, that it must become a new row?

Can anyone help, please?

Have not found any solution... :(
