DataGridView.CellValueChanged does not work with bound DataGridView

Question

When I change the value programmatically in the DataTable to which the DataGridView is bound, the corresponding CellValueChanged event does not fire for the DataGridView. I am trying to change the background color of a cell based on the value of the cell when the DataTable is populated with data without repeating each row and checking each value.

Answer 1

Do you change DataTabledirectly and expect the event DataGridViewto be fired? I suggest you change the value of the cell programmatically as follows:

DataGridView[ColumnIndex, RowIndex].Value = NewValue;

, DataGridView.CommitEdit(), DataTable. CellValueChanged.
