I have used
protected void Addition_Click(object sender, EventArgs e)
{
int num1 = Convert.ToInt32(number1.Text);
int num2 = Convert.ToInt32(number2.Text);

answer.Text = (num1 + num2).ToString();


}

protected void Subtraction_Click(object sender, EventArgs e)
{
int num1 = Convert.ToInt32(number1.Text);
int num2 = Convert.ToInt32(number2.Text);

answer.Text = (num1 - num2).ToString();
}

I was just wondering if I could avoid duplicating

int num1 = Convert.ToInt32(number1.Text);
int num2 = Convert.ToInt32(number2.Text);

I know it is a simple application. But im learning and thought I could make it more efficient thats all

I just wanted to be efficient when using the textbox values by either putting them in a class and storing them as a variable maybe and then using them in the click event by either adding or subtracting the values and placing them in a label. It seems this may not be possible.

However I know how to call the textbox values serperately for each event.

I set an ID to the list item and then used .visible = false.

How can i do this server side. I need it to happen when the session is null.
