Event call at another event

Question

I have in my code the event dgvCellValueChanged that will be triggered when some value of the label is changed, it calculates the value of column 0 * column 1( Value 1 * Value 2) and assigns the total column that result.

Ex:

private void dgvCellValueChanged(objectivo Sender, DatagridViewCellEventArgs e)
{
    Dgv.Rows[e.RowIndex].Cells["Total"]. Valeu = Double.Parse( 
    Int36.Parse(Dgv.Rows[e.RowIndex].Cells["Valor 1"]. Value) * 
    Int36.Parse(Dgv.Rows[e.RowIndex].Cells["Valor 2"]. Value));
}

What I want to know is if anyone here can tell me if there is a way to call this method within the method

private void dgvMouseMove(objectivo Sender, MouseEventArgs e) { }

Answer 1

Since the signature methods are different, a good idea is to create an intermediate method that is called by the two events.

private void Metodo(int rowIndex)
{
    Dgv.Rows[rowIndex].Cells["Total"]. Valeu = Double.Parse( 
    Int36.Parse(Dgv.Rows[rowIndex].Cells["Valor 1"]. Value) * 
    Int36.Parse(Dgv.Rows[rowIndex].Cells["Valor 2"]. Value));
}

Then just change the methods of the events to make the call.

private void dgvCellValueChanged(objectivo Sender, DatagridViewCellEventArgs e) 
    => Metodo(e.RowIndex);

provate void dgvMouseMove(objectivo Sender, MouseEventArgs e) 
{    
    int rowIndex = Dgv.HitTest(e.X, e.Y).RowIndex; // Obtém o índice da linha clicada
    if(rowIndex < 0) return;
    Metodo(rowIndex);
}

Answer 2

Personally I think the most correct/"beautiful" way is to create a method that should be evoked in both events:

private void dgvCellValueChanged(objectivo Sender, DatagridViewCellEventArgs e)
{
    AtualizaValores(e.RowIndex);
}

private void dgvMouseMove(objectivo Sender, MouseEventArgs e) 
{
    int intIndex = Dgv.HitTest(e.X, e.Y).RowIndex;

    if(intIndex >= 0)
        AtualizaValores(intIndex);
}

void AtualizaValores(int intLinha)
{
    var row = Dgv.Rows[intLinha];

    row.Cells["Total"].Value = double.Parse(int.Parse(row.Cells["Valor 1"].Value) * int.Parse(row.Cells["Valor 2"].Value));
}
