Calculating with a hidden number

Design:

ComboBox1__txtBox1__txtBox2___txtBox3

When you select a name in comboBox1 a number is called with DataBinding in txtBox1 and txtBox2. 

double a1 = Convert.ToDouble(textBox1.Text);
double b1 = Convert.ToDouble(textBox2.Text);

textBox3.Text = (a1 * b1).ToString();

How can I make this so that the textBox2 wouldn't be seen in the design. If I set textBox2 Properties Visible to false I get an error.

Try to use this. 

<asp:HiddenField id="InvisibleField" runat="server" />

Assign the result of (a1 * b1).ToString(); to "InvisibleField".
