To link two pices of codes with condition

Israel

Hi,

I have four textboxs (txtResultA, txtResultB, txt_SoldForResultA, txt_SoldForResultB).

The two txtBoxes: txtResultA, txtResultB doing one operation. But when one of these txtBoxes have a number superior to another one. The result should be displayed on txt_SoldForResultA or txt_SoldForResultB.

For example, txtBoxA.Text (100) – txtBoxB.Text (70) = 30 (should appear on txt_SoldForResultA).

Another example is, txtBoxA.Text (70) – txtBoxB.Text (100) = 30. For this result should be appear on txt_SoldForResultB.

double d1, d2, total0;

double.TryParse(txtBoxA.Text, out d1);

double.TryParse(txtBoxB.Text, out d2);

total0 = d1 - d2;

txtBox_SoldForA.Text = total0.ToString("N2");

/////// Need to link these two pieces of code to do what I explained

double d3, d4, total1;

double.TryParse(txtBoxA.Text, out d3);

double.TryParse(txtBoxB.Text, out d4);

total1 = d3 - d4;

txtBox_SoldForB.Text = total1.ToString("N2");

            if (!string.IsNullOrWhiteSpace(txtResultA.Text) && !string.IsNullOrWhiteSpace(txtResultB.Text))
            {
                float A = 0;
                float B = 0;
                float.TryParse(txtResultA.Text, out A);
                float.TryParse(txtResultB.Text, out B);
                if (A > B)
                {
                    txt_SoldForResultA.Text = (A - B).ToString("N2");
                    txt_SoldForResultB.Text = string.Empty;
                }
                else if (A < B)
                {
                    txt_SoldForResultB.Text = (B - A).ToString("N2");
                    txt_SoldForResultA.Text = string.Empty;
                }
            }
        }
        private void txtResultB_TextChanged(object sender, EventArgs e)
        {
