I am trying to clean a Datagridview from C#. However when executing Rows.Clear(), before that he is running an event CellValidating which is also attached to Datagridview

You can not perform the validation before clearing the records?

    It is probably impossible to cause the event not to be triggered. If the event has some side effect then run the Clear could be a good sign that you’re using the wrong event.

You can always create a control variable, which is true before doing the Rows.Clear() and passes to false immediately afterwards:

private bool isClearing = false;

// ...

isClearing = true;
Rows.Clear();
isClearing = false;

// ...

private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
    if(isClearing)
    {
        // return ou simplesmente e.Cancel = true;
        // dependendo das necessidades
        return;
    }

    // ...
}
