Greetings All,
I have a window with a datawindow that presents a grid to a user. When they enter a base rate, it triggers the change event which does a lot of calculations and does setitem on a bunch of other columns as shown here:
BASE GRATUITY DISCOUNT TAX TOTAL
100 20 10 6 116
50 10 5 3 58
ETC...
So the value of gratuity, discount, tax and total comes from the user entering or changing the base rate. The value of gratuity percent, discount percent and tax percent are handled in a different window and stored in a different table.
And here is the problem. The user might create a few hundred rates. And a week later the tax rate changes in their state and instead of the tax being 6% it is now 7%. So I need to pull all of the rates in either a hidden window or a datastore effect the original calculations on every single row using the new tax percent (or new gratuity percent or new discount percent) and have all of the values recalculated and saved to the database.
Just as a note, if I made the user redo the calculations it would not work because they can only enter the base rate and in this case it is not changing so the changed event would never fire.
So I am looking for a way to pull up all of these rows in a window/datawindow and fire the changed event so that every row is automatically recalculated using the same value for base rate and the current values for gratuity, discount and tax.
Can someone kindly suggest how best to do this? BELOW IS THE CODE IN THE CURRENT ITEMCHANGED EVENT...
Thank you!!
Paul
