Hi guys.
I have a String variable which works like a Boolean. The data will be "Male" or "Female".
So I Bind RadioButton to it in two way mode.
But I don't know it doesn't work!
Any Help please?

UPDATE:
I changed the IsChecked to Visibility. And it works!!! I mean it changes the visibility!!!
I got confused!

What I have tried:

XML

<RadioButton x:Name="RadioButtonGenderInSubtitleDataGridFEMALE"
             Grid.Row="1"
             Grid.Column="0"
             HorizontalAlignment="Right"
             VerticalAlignment="Stretch"
             HorizontalContentAlignment="Center"
             VerticalContentAlignment="Center"
             Foreground="White" 
             BorderThickness="1"
             Content=""
             ClickMode="Release" 
             IsChecked="False">
    <RadioButton.Style>
        <Style TargetType="RadioButton">
            <Style.Triggers>
                <DataTrigger Binding="{Binding GenderOfCharacter}" Value="Female">
                    <Setter Property="IsChecked" Value="True"/>
                 </DataTrigger>
                 <DataTrigger Binding="{Binding GenderOfCharacter}" Value="Male">
                     <Setter Property="IsChecked" Value="False"/>
                 </DataTrigger>
             </Style.Triggers>
        </Style>
     </RadioButton.Style>
</RadioButton>

You're treating a RadioButton like a CheckBox. It only has meaning in the context of 2+ RadioButtons.

Because it expects a boolean value?

Use an IValueConverter for binding conversions. Here is more information: Value conversion with IValueConverter - The complete WPF tutorial[^]

@Maciej
What do you mean by 5ed! ?

I voted for that answer: 5 stars (see right-top corner).

No it doesn't related to boolean value. I tested with a boolean but no luck.
Also as I mentioned in Update, I accidentally changed the IsChecked to Visibility. And it works!!! I mean when I set to change the Visibility, it works. But when I set IsChecked, it doesn't work.

I did not check the value type. However, unless you're passing the right value type at the binding, you need to use a converter to convert from one value type to another.

I have pointed you to a WPF tutorial site that explains all of this.
