Is it possible to let only a user selection trigger a SelectionChanged event on a DataGridView?

Question

SelectionChanged methods are triggered when the selection is changed by program. So, for example, calling dataGridView.ClearSelection() or dataGridView.Rows[0].Selected = true would call the method

private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
}

Is it possible to execute code only when the user changed the selection, e.g. by selecting a row/cell with the mouse or keyboard?

Answer 1

You will have to code this in

private bool _programmaticChange;

private void SomeMethod()
{
    _programmaticChange = true;
    dataGridView.ClearSelection();
    _programmaticChange = false;
}


private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
    if (_programmaticChange) return;
    // some code
}

this will make it run only on user actions
