Well that depends on if you are performing the multiplication at the client side using javascript, or at the server in the codebehind using c#, vb.net etc.

Counter 5!

Solution 3

C#

double firstValue = Convert.ToDouble(TextBox1.Text);
        double secondValue = Convert.ToDouble(TextBox2.Text);
        double total = firstValue * secondValue;
        TextBox3.Text = total.ToString();

Use it.

In .aspx page,

XML

<asp:TextBox ID="txtValue1" runat="server"></asp:TextBox>
                <asp:TextBox ID="txtValue2" runat="server"></asp:TextBox>
                <asp:Button ID="btnMultiply" runat="server" Text="Multiply" OnClick="btnMultiply_Click" />
                <asp:TextBox ID="txtAnswer" runat="server" ReadOnly="true" Style="background-color: Gainsboro"></asp:TextBox>

In .aspx.cs page,

C#

protected void btnMultiply_Click(object sender, EventArgs e)
    {
        if (txtValue1.Text == string.Empty || txtValue2.Text == string.Empty)
            Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Enter values in two textboxes')", true);
        else
        {
            int value1 = Convert.ToInt32(txtValue1.Text);
            int value2 = Convert.ToInt32(txtValue2.Text);
            txtAnswer.Text = Convert.ToString(value1 * value2);
        }
    }
