I'm not entirely sure what I'm doing incorrect but it appears that my style trigger is not being recognized. I want to change the color of the Stroke when the listbox item is selected.
<ListBox ItemsSource="{Binding CityList}" DisplayMemberPath="Name" SelectionMode="Extended"

<Setter Property="BorderThickness" Value="3" />
<Setter Property="ContentTemplate">

</DataTemplate>
</Setter.Value>
</Setter>

</ListBox>
You can't use TargetName in a Style Setter.
Instead of setting the ContentTemplate property, you may set the Template property and add the Trigger to the ControlTemplate.Triggers collection:
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid>
<Ellipse x:Name="indicator"
Fill="#FF000000"
Height="10"
Width="10"
Stroke="Transparent"
StrokeThickness="2"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="indicator" Property="Stroke" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
You may also add a ContentPresenter to the Grid in the ControlTemplate, which would display the elements of the ItemTemplate (if you later decide to declare one).
I am currently using the XAML below to change the image on a toggle button for each state. How can I define a template or style that will allow me to define the images that are to be used in the button definition such that I don't have to repeat everything below for each button. Is this even possible ?
Ideally I would like to define a template with properties such as 'checkedImage', 'uncheckedImage' and then set these properties in the button definition in Designer.
I would also like the button to prevent the display of any other states or animations but I can't seem to prevent the background changing when the button is selected or when there is a mouseover. Are there some additional states that I don't have defined below?
Sample code (XAML, C#) for the style or template and for the actual toggle button definition would be appreciated. Also any references to 'simple' samples and explanations would be appreciated.
Thanks
EDIT: Update with my latest attempt...
This almost works - the correct image never gets displayed when the button is Checked. Any ideas what I am missing here?
<Style x:Key="ImgToggleButton" TargetType="ToggleButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Grid x:Name="GD" Background="White">
<ContentPresenter x:Name="CP" Content="{TemplateBinding Content}"></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content">
<Setter.Value>
<Image Source="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType=ToggleButton}}" Stretch="Uniform"/>
</Setter.Value>
</Setter>
<Setter TargetName="GD" Property="Background" Value="{DynamicResource ThemeSolidColorBrushBlue}"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="GD" Property="Background" Value="White"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<!-- Nothing so we have no change-->
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And here is the button definition
<ToggleButton x:Name="allTestsToggleButton" Tag="Asset/AllTestsButton_1.png" Style="{DynamicResource ImgToggleButton}" ClickMode="Press" Checked="allTestsToggleButton_Checked" Unchecked="allTestsToggleButton_Unchecked" Grid.Row="2" Grid.Column="3" Grid.ColumnSpan="5">
<ToggleButton.Content>
<Image Source="Assets/AllTestsButton_0.png" Stretch="Uniform"/>
</ToggleButton.Content>
</ToggleButton>
Setting TargetName="CP" does not work either
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="CP" Property="Content">
<Setter.Value>
<Image Source="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType=ToggleButton}}" Stretch="Uniform"/>
</Setter.Value>
</Setter>
<Setter TargetName="GD" Property="Background" Value="{DynamicResource ThemeSolidColorBrushBlue}"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="GD" Property="Background" Value="White"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<!-- Nothing so we have no change-->
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
Update1
You can use this style for multiple button with different images and I have used tag for storing image for checked state true and use templatebinding for default look i.e state=false
<Window.Resources>
<BitmapImage x:Key="imag1" UriSource="image1.jpg"></BitmapImage>
<BitmapImage x:Key="imag2" UriSource="path.jpg"></BitmapImage>
<Style TargetType="ToggleButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Grid x:Name="GD" Background="{TemplateBinding Background}">
<ContentPresenter></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="GD" Property="Background">
<Setter.Value>
<ImageBrush ImageSource="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType=ToggleButton}}"></ImageBrush>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<ToggleButton x:Name="sampleTestToggleButton" Tag="{StaticResource imag2}" ClickMode="Press" Grid.Row="4" Grid.Column="3" BorderBrush="Transparent" Foreground="Transparent">
<ToggleButton.Background>

</ToggleButton.Background>
</ToggleButton>

I think, you need for the ability to use vector graphics in WPF. In this case, to use the Path, where in Data to the specified coordinates on which the object is drawn MSDN.
Advantages:
Do not store it in the files, smaller size
Do not store this files in Resources
Dynamically changing color, size and the whole shape
The Minuses, in my opinion:
You can not always find the right Data for the Path
About minus: There are special sites, like www.modernuiicons.com and utilities for converting the image to Data. For converting Image to Vector graphics (Path) use Inkscape, him free and very useful. For more information see this link:
Vectorize Bitmaps to XAML using Potrace and Inkscape

Output
I have a treeview with buckets and parts. Everything looks great except one feature. A property on bucket (bool IsEditable) allows the user to toggle editing on or off within the tree view for that node. But for some reason when wpf displays the collection of buckets in the treeview the togglebuttons do not show the proper text
Here is my xaml:
<Style TargetType="{x:Type ToggleButton}" x:Key="Editor">
<Style.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Content">
<Setter.Value>
<TextBlock Text="Edit"/>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content">
<Setter.Value>
<TextBlock Text="Done"/>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
<DataTemplate x:Key="HierarchialItemTemplate">

<TextBlock Text="{Binding PartNum}"/>

</DataTemplate>
<DataTemplate x:Key="DisplayBucket">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Sequence}"/>
<TextBlock Text=" "/>
<TextBlock Text="{Binding Description}"/>
<ToggleButton IsChecked="{Binding IsEditable}" Width="25" Style="{StaticResource Editor}"/>
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="EditBucket">
<StackPanel Orientation="Horizontal">
<TextBox Text="{Binding Sequence}"/>
<TextBlock Text=" "/>
<TextBox Text="{Binding Description}"/>
<ToggleButton IsChecked="{Binding IsEditable}" Width="25" Style="{StaticResource Editor}"/>
</StackPanel>
</DataTemplate>
<HierarchicalDataTemplate x:Key="TreeTemplate"

ItemsSource="{Binding Parts}"
ItemTemplate="{StaticResource HierarchialItemTemplate}"

<ContentPresenter Content="{Binding}"

</HierarchicalDataTemplate>
<Style TargetType="{x:Type ContentPresenter}" x:Key="TreeNodeStyle">
<Setter Property="ContentTemplate" Value="{StaticResource DisplayBucket}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding IsEditable}" Value="True">
<Setter Property="ContentTemplate" Value="{StaticResource EditBucket}"/>
</DataTrigger>
</Style.Triggers>
</Style>
The above is window.resources. In the Grid is
<TreeView x:Name="Buckets"
ItemsSource="{Binding Model.Job.Buckets}"
ItemTemplate="{StaticResource TreeTemplate}"
>
So for whatever reason when I add nodes I get a bucket with a toggle button, but the toggle button text only shows up for the last node added. If I click a toggle button, the text disappears out of the previous toggle button and shows up in the one just clicked. The effect is similar to what this person experienced, but I have no idea what the guy was talking about who answered the question ToggleButton Style only works on last ToggleButton.
Any thoughts?
You have couple of options (ordered from least to most dramatic):
1) Content
<Style TargetType="{x:Type ToggleButton}" x:Key="Editor">
<Style.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Content" Value="Edit" />
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="Done" />
</Trigger>
</Style.Triggers>
</Style>
2) ContentTemplate
<Style TargetType="{x:Type ToggleButton}" x:Key="Editor">
<Style.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="Edit"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="Done"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
3) ControlTemplate
<Style TargetType="{x:Type ToggleButton}" x:Key="Editor">
<Style.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<TextBlock Text="Edit"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<TextBlock Text="Done"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
The reason why your approach didn't work is that TextBlock control is created only once (i.e. not created as part of template - ControlTemplate or DataTemplate).
I created a custom WPF control which displays the value of the Weight property which is an int. When the user clicks on the custom control or when the control gets the focus, the user should be able to edit the value of the Weight property.
To accomplish this, I tried the following:
If the control is "inactive", the Weight property will be displayed
in a TextBlock.
If the control gets the focus, the Weight property
will be displayed in a TextBox.

The problem with this custom control style is that when the user clicks into the TextBox, the trigger will change the control template to the TextBlock. How can I fix this?
Try using the IsKeyboardFocusWithin property instead. I believe this will do what you need.
<Style.Triggers>
<Trigger Property="IsKeyboardFocusWithin" Value="True">
<Setter Property="Template" Value="{StaticResource Control_Focused}" ></Setter>
</Trigger>
<Trigger Property="IsKeyboardFocusWithin" Value="False">
<Setter Property="Template" Value="{StaticResource Control}" ></Setter>
</Trigger>
</Style.Triggers>
