I think you need to handle null or empty check before calculation.. decimal d3 = 0M; if (!String.IsNullOrEmpty(TextBox2.Text.Trim())) Decimal.TryParse(TextBox2.Text.Trim(), out d3); //if (!Decimal.TryParse(TextBox2.Text.Trim(), out d3)) // throw new FormatException("TextBox2 - IsNullOrEmpty"); decimal d4 = 0M; if (!String.IsNullOrEmpty(TextBox3.Text.Trim())) Decimal.TryParse(TextBox3.Text.Trim(), out d4); //if (!Decimal.TryParse(TextBox3.Text.Trim(), out d4)) // throw new FormatException("TextBox3 - IsNullOrEmpty"); TextBox4.Text = Convert.ToString(d3 * d4);

Hi Narasiman, private void button1_Click(object sender, EventArgs e) { textBox5.Text = (decimal.Parse(textBox3.Text) * decimal.Parse(textBox4.Text)).ToString(); } Thanks

Try: decimal d3 = Convert.ToDecimal(textbox3.Text); decimal d4 = Convert.ToDecimal(textbox4.Text); decimal result = d3 * d4; textbox5.Text = result.ToString();
