WPF binding - binding to A when checking X and also binding to B

Basically I have a TextBlock that displays the microphone gain.

<TextBlock FontFamily="Calibri Light" FontSize="20" Foreground="#FFF65B60" FontWeight="Bold" Height="35"><Run Text="{Binding AudioRecorder.Gain, StringFormat={}Microphone Gain: {0:#} %}"/></TextBlock>

As you can see it is related to "AudioRecorder.Gain", however I only want to bind to this value if this checkbox is NOT checked.

<CheckBox IsChecked="{Binding Recognizer.AutoGainControl}"

if it is installed i want to bind to

"Recognizer.Gain"

Is something like this possible or do I need to combine two variable gains together?

I'm not sure if you succeeded or not, but some example should stay here for others who may be looking for the same thing:

I gathered some information and created a version of this:

<Window x:Class="ComboItems.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:windows="clr-namespace:System.Windows;assembly=PresentationCore"
    xmlns:system="clr-namespace:System;assembly=mscorlib"
    Title="MainWindow" Width="525">
<Window.Resources>
    <x:Array x:Key="data1" Type="{x:Type system:String}">
        <system:String>Item1</system:String>
        <system:String>Item2</system:String>
        <system:String>Item3</system:String>
    </x:Array>
    <ObjectDataProvider x:Key="visibilityValues" 
                            ObjectType="{x:Type system:Enum}"
                            MethodName="GetValues">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="windows:Visibility" />
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>
</Window.Resources>

<Grid>
      <StackPanel>
        <RadioButton Content="RadioButton1" Name="Radio1" GroupName="radio"  />
        <RadioButton Content="RadioButton2" Name="Radio2"   GroupName="radio"  />
        <ListBox Name="listbox">
            <ListBox.Style>
                <Style TargetType="ListBox">
                    <Setter Property="ItemsSource">
                        <Setter.Value>
                            <Binding Source="{StaticResource data1}" />
                        </Setter.Value>
                    </Setter>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Path=IsChecked, ElementName=Radio1}" Value="True" >
                            <Setter Property="ItemsSource">
                                <Setter.Value>
                                    <Binding Source="{StaticResource data1}" />
                                </Setter.Value>
                            </Setter>
                        </DataTrigger>
                        <DataTrigger Binding="{Binding Path=IsChecked, ElementName=Radio2}" Value="True" >
                            <Setter Property="ItemsSource">
                                <Setter.Value>
                                    <Binding Source="{StaticResource visibilityValues}" />
                                </Setter.Value>
                            </Setter>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </ListBox.Style>
        </ListBox>
    </StackPanel>
  </Grid>
</Window>


DataTrigger

will do the job here and according to the property IsChecked

how RadioButton

it will change the source ListBox

.

Also, I used to bind to enums with the System.Enum

types method GetValues

, which accepts Type

so that it knows what enum values ​​it should return.

The above sample should work without any modification.
