These three (Plot, Space and Tenant) of Report Views use the same base LedgerView that contains Header, Entries and Footer sections:

Date, Particulars, ... are in Header, Total is in Footer and a ListBox in Entries section. The Header and Footers are aligned but the ListBoxItems are not, probably, because those ListBoxItems use some Padding by default. I want to get ListBoxItem's left and right padding and set those as the left/right padding of my Header and Footer in order to get everything aligned.
How to get that Padding?
EDIT
After some trials, looks like 5 in left/right padding makes it aligned properly. Is there anything in the SystemParameters or somewhere, I can get the value from?
