thanks, you saved me a bunch of time with this!

Hey.Thanks, It save a lot of time..
Nice article for wpf beginner.

thanks a lot. it was very annoying

Not sure what the underlying problem is... but it fixed it for me as well.

Thanks! it really helped :)

If you want to use image as a content - the "Content" property don't gives you expected result. You may use "ContentTemplate" property. For example:
<ToggleButton Width="32" Height="32">
<ToggleButton.Style>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="ContentTemplate" >
<Setter.Value>
<DataTemplate>
<Image Source="{StaticResource imgToggle1}"/>
</DataTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Image Source="{StaticResource imgToggle2}"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ToggleButton.Style>
</ToggleButton>

I tried this and it didn't work for me at all. I have no idea what I'm doing wrong...

<Style x:Key="MyToggleButton" TargetType="{x:Type ToggleButton}">
<Setter Property="Foreground" Value="White"/>
<Setter Property="MinWidth" Value="80"/>
<Setter Property="MinHeight" Value="26"/>
<Setter Property="Margin" Value="4"/>
<Setter Property="Background" Value="#FFE54C4C"/>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Background" Value="#FF8BBA7C"/>
</Trigger>
</Style.Triggers>
</Style>

You need to "show" to Content how it will be changing (change-rule) when some trigger is a rising. So use ContentTemplate like some posted above.

Victor's answer was a simply true. You should use a ContentTemplate. And in the ContentTemplate you should reassign Triggers rules and style propertyes. Thanks!
