Hide zero values with StringFormat

Question

I made a similar question months ago

In this case I have a textblock like this

<TextBlock FontSize="28" Text="{Binding DataPoint.Y, StringFormat=\{0:0\\%\}}" Foreground="Black">

As you can see, my StringFormat puts a '%' sign after the number, if my data is 0.0 (I fill the component in code behind, my variable is a double) I get "0%"

But now I want to get "" if my text is 0.0

So far I have this:

 Text="{Binding DataPoint.Y, StringFormat=\{0:#.#\\%\}}"

But this retrieves "%", how can I get ""?

Answer 1

This worked for me

{0:#\\%;0:#;#}

Answer 2

None of these worked for simple positive integers. I had a field which would always default to 0. To hide it, but not add any decimals places, I use:

Text="{Binding BuyerNumber, StringFormat=0;;#}"

Hope this helps someone out who is looking for integers only.

Answer 3

Use Custom Numeric Format Strings. Specifically, see the ";" Section Separator.

Using {0:#.#\\%;-#.#\\%;} will give you the desired output, I believe.
