Just wanted to know how I would go about taking multiple values in a ListView and performing a calculation with them. Right now the ListView accepts up to 40 rows of data from the user.. each row contains a value for "hours" and "grade. I need to multiply the hours by grade for each row then divide that number by the total amount of rows filled. Heres a small example.

Subject____Hours___Grade

MATH_____11______4
COMM____11______4.5
DBAS_____9_______3
GNED_____8 _______5

If those are the values in the ListView I would need to do the calculation for those + each time a new row is added the final result is updated.

11 x 4 = 44
11 x 4.5 = 49.5
9 x 3 = 81
8 x 5 = 40

total points = 214.5

final result = total points / number of rows

Two ways I can think of are either:

1. Sum up the items manually when you add each new item. You can loop the items in the ListView and obtain each columns value from the SubItem property.

2. Create your own custom ListView control that will expose an OnItemAdded event to allow you to update only when needed and such.

Btw 9 x 3 = 81 isn't correct

How would I go about multiplying the hours and GPA columns together for each row... Could you show me an example (code) what it would look like.

Lets say your ListView is named listView1. You can loop each item using:

Alright that worked but the first value is always 0...

^^ Fixed that ^^

Now I need to limit the amount of items in the viewlist to 40.

Inside your 'Add' button call at the top, check if the listView1.Items.Count == 40, if it is just exit the function.
