    Maybe a silly idea, but surely the easiest would be to insert € symbol in the Textbox during design time ( in its Text property press Alt + 0128 ) then do something like :

    Code:
    txtFinEuros.Text += (Convert.ToDecimal(txtBoxBrick.Text) * Convert.ToDecimal(textBoxLength.Text) * Convert.ToDecimal(txtEuros.Text)* Convert.ToDecimal(textBoxWidth.Text));
    But it is strange though, if you have set up your PC's Regional settings properly to show Euros as a Currency symbol, this would not have been an issue, then you could have just done this :

    Code:
    txtFinEuros.Text = (Convert.ToDecimal(txtBoxBrick.Text) * Convert.ToDecimal(textBoxLength.Text) * Convert.ToDecimal(txtEuros.Text)* Convert.ToDecimal(textBoxWidth.Text)).ToString("C");

    I thought you'd have figured out by now that because we are adding the € sign manually, it gest seen as a string, and therefore cannot be used in calculations. I'd suggest usinag a variable o store the calculation, then, add the € and the variable in the textbox.

    You are replacint content of the txtFinEuros. Swap the steps and append:
    Code:
    txtFinEuros.Text = (Convert.ToDecimal(txtBoxBrick.Text) * Convert.ToDecimal(textBoxLength.Text) * Convert.ToDecimal(txtEuros.Text) * Convert.ToDecimal(textBoxWidth.Text)).ToString("F"); 
    
    txtFinEuros.Text = txtFinEuros.Text + "";
