There is a feature of mathematics known as multiplication where (in simple terms)
product = value times multiplier.
Now if you have a proper programming question perhaps you would like to edit the above and fill in the details.

You do have to wonder why some of these people have chosen a career in IT...:sigh:

What have you tried?

this is what ive tried
If Combo1.SelectedItem <= 20 Then
txtBox2.Text = 20
txtBox3.Text = Combo1.SelectedItem * txtBox2.Text
ElseIf Combo1.SelectedItem <= 50 Then
txtBox2.Text = 15
txtBox3.Text = Combo1.SelectedItem * txtBox2.Text
ElseIf Combo1.SelectedItem <= 100 Then
txtBox2.Text = 12
txtBox3.Text = Combo1.SelectedItem * txtBox2.Text
ElseIf Combo1.SelectedItem <= 500 Then
txtBox2.Text = 8
txtBox3.Text = Combo1.SelectedItem * txtBox2.Text
ElseIf Combo1.SelectedItem >= 500 Then
txtBox2.Text = 5
txtBox3.Text = Combo1.SelectedItem * txtBox2.Text

I would suggest you spend some time reading the documentation on the combobox class. You also need to understand the difference between strings (text characters) and integer values (numbers) and how you can convert between and manipulate the two different types.

Solution 1

Convert them to numbers, using Parse or TryParse, and (as Richard says) use the multiplication operator "*" to produce a result:

C#

int x = int.Parse(myCombo.SelectedItem.ToString());
int y = int.Parse(myTextbox.Text);
int res = x * y;

Solution 2

C#

int item1 =int.Parse(Product.SelectedValue.ToString());
int unitPrice=int.Parse(UnitPrice.SelectedValue.ToString());

int result = item1 *  unitPrice
