WPF binding StringFormat syntax

Question

How can I format a decimal value conditionally in a WPF window?

1. Value should be rounded to a whole number (Ex: 1,234)
2. When the value is 0.00, it shoul

Answer 1

The extra 0 comes from the 0 after the colon.

Instead, try {}{0:#,0}.

From the MSDN docs on Custom Numeric String formats (emphasis added):

"0" | Zero placeholder | Replaces the zero with the corresponding digit if one is present; otherwise, zero appears in the result string.
