I have a WPF application and one page shows two stack panels with radio buttons in them. I want to have it so that the visibility of the second stack panel is dependent on whether certain radio buttons are selected or not.
<Grid Background="#F8FBFD">
<StackPanel x:Name="StackType" HorizontalAlignment="Center" Orientation="Horizontal" Margin="0,93,0,428">
<materialDesign:Card Padding="32" Margin="16">
<StackPanel>
<TextBlock HorizontalAlignment="Left" Style="{DynamicResource MaterialDesignTitleTextBlock}" >Installation Type</TextBlock>
<RadioButton Checked="NewMode_Checked" Content="New " x:Name="rbtnNew" GroupName="InstallType" IsChecked="{Binding newMode, Mode=TwoWay, Source={StaticResource modes}}"/>
<RadioButton Checked="UpgradeMode_Checked" Content="Update" x:Name="rbtnUpgrade" GroupName="InstallType" IsChecked="{Binding upgradeMode, Mode=TwoWay, Source={StaticResource modes}}" />
<RadioButton Checked="ChangeMode_Checked" Content="Change" x:Name="rbtnChange" GroupName="InstallType" IsChecked="{Binding changeMode, Mode=TwoWay, Source={StaticResource modes}}" />
</StackPanel>
</materialDesign:Card>
</StackPanel>
<StackPanel x:Name="StackMode" HorizontalAlignment="Center" VerticalAlignment="Center" Orientation="Horizontal" Visibility="Visible">
<materialDesign:Card Padding="32" Margin="16" Width="204" Height="147">
<StackPanel>
<TextBlock HorizontalAlignment="Left" Style="{DynamicResource MaterialDesignTitleTextBlock}" >Installation Mode</TextBlock>
<RadioButton Content="Default Settings" Name="rbtnDefaultMode" IsChecked="{Binding defaultMode, Source={StaticResource modes}, Mode=TwoWay}" Checked="defaultSettings_Checked"/>
<RadioButton Content="Custom Settings" Name="rbtnCustomMode" IsChecked="{Binding customMode, Source={StaticResource modes}, Mode=TwoWay}" Checked="customSettings_Checked"/>
</StackPanel>
</materialDesign:Card>
</StackPanel>
</Grid>
In this, I want to have it in a way so that if rbtnNew
or rbtnUpgrade
are selected, only then should the StackMode
panel be should be visible. And if rbtnChange
is selected, the panel StackMode
panel should stay hidden.
You can add a custom style with a DataTrigger
:
Visibility="Visible"
from the StackMode
panel.Setter
that sets the default value of Visibility
of the StackPanel
to Visible
.DataTrigger
that sets its value to Collapsed
(or Hidden
) if the IsChecked
value of rbtnChange
is true
. You can refer to the element with ElementName
in the binding.<Grid Background="#F8FBFD">
