C# 'if' Binding value

Question

I've got a list view that is populated by a Binding, on a class named House.

Here's an example of my code:

<DataTemplate DataType="house">
    <TextBlock Text="{Binding sold_status}" />
</DataTemplate>

As you can see, one of my variable names is sold_status. This is a bool.

I want to show either "SOLD" or "NOT SOLD" for 1 and 0 respectively.

Is it possible to fashion an if statement based on the value?

So just so that you can visualise what I want to achieve:

<DataTemplate DataType="house">
    <TextBlock Text="({Binding sold_status} == 1) 'SOLD' else 'NOT SOLD'" />
</DataTemplate>

Answer 1

You'll want to create a Style with DataTriggers in to set the properties as needed. You could also use a converter, but changing UI control properties based on underlying data is exactly what triggers/styles are all about.

..In fact, I can see you're basically 'converting' sold_status to a bit of text. For that, use a converter. I'll post a quick example..

See the top answer here: WPF: Display a bool value as "Yes" / "No" - it has an example converter class you could repurpose.

Answer 2

Look up the IValueConverter interface for an example. Implement the Convert method to return the text you want to display.
