Button with round edge grid and set disable button color to green

I want to have a button with round edge grid and set disable button color to gray, green otherwise. Attached snippet of code. I don't know how to change the default. If I disable my button, I get the output as the image on the left, however, I want it to look like the image on the right!
<Button x:Name="button" Height="30" Width="100" Margin="825,0,0,0" Background="Transparent"
BorderThickness="0" BorderBrush="Transparent">
<Button.Content>
<Border CornerRadius="12.5" Height="25" Width="95" Margin="0" BorderBrush="Gray"
BorderThickness="4,4,4,4" Background="Gray">
<TextBlock Text="Back" HorizontalAlignment="Center" VerticalAlignment="Top"
Margin="12,0,13,0" Foreground="White"/>
</Border>
</Button.Content>
</Button>

Content is only one part of Button. The rest is determined by Template.
If multiple buttons should have custom apperance, the Template should be set in buttons Style. For one button it can be done inplace:
<Button x:Name="button" Content="Back" Height="30" Width="100" Margin="825,0,0,0" Background="Transparent"
BorderThickness="0" BorderBrush="Transparent">
<Button.Template>
<ControlTemplate TargetType="Button">
<Border CornerRadius="12.5" Height="25" Width="95" Margin="0" BorderBrush="Gray"
BorderThickness="4,4,4,4" Background="Gray">
<TextBlock Text="{TemplateBinding Content}"
HorizontalAlignment="Center" VerticalAlignment="Top"
Margin="12,0,13,0" Foreground="White"/>
</Border>
</ControlTemplate>
</Button.Template>
</Button>
if you are going to reuse the template, declare it as Resource
<Window.Resources>
<ControlTemplate TargetType="Button" x:Key="RoundBtn">
<Border Name="roundBorder" CornerRadius="12.5" Height="25" Width="95" Margin="0" BorderBrush="Gray"
BorderThickness="4,4,4,4" Background="Gray">
<TextBlock Text="{TemplateBinding Content}"
HorizontalAlignment="Center" VerticalAlignment="Top"
Margin="12,0,13,0" Foreground="White"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="roundBorder" Property="Background" Value="Green"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Window.Resources>
and set button Template using resource:
<Button x:Name="button" Content="Back" Height="30" Width="100"
Template="{StaticResource RoundBtn}"
Margin="825,0,0,0" Background="Transparent"
BorderThickness="0" BorderBrush="Transparent"/>

This should work for you. I've used an outer grid with a blue background so that I could be sure it was all working, but just remove that and move the style to whichever resources you need to. Explanation as comments within the xaml:
<Grid Background="Blue">
<Grid.Resources>
<!-- Override the default button style, otherwise you get a grey
rectangle behind the ellipse when disabled -->
<Style TargetType="Button" x:Key="MyButtonStyle">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="Transparent" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid Background="{TemplateBinding Background}">
<ContentPresenter x:Name="MyContentPresenter"
Content="{TemplateBinding Content}"
HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Grid.Resources>
<Button x:Name="button" Height="30" Width="100"
BorderThickness="0" BorderBrush="Transparent" IsEnabled="false"
Style="{StaticResource MyButtonStyle}">
<Button.Content>
<Border CornerRadius="12.5" Height="25" Width="95">
<Border.Style>
<Style TargetType="Border">
<!-- Button is gray by default, i.e. when enabled -->
<Setter Property="Background" Value="Gray"/>
<Style.Triggers>
<!-- If the button becomes disabled then it becomes green -->
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="Green" />
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
<TextBlock Text="Back" HorizontalAlignment="Center" VerticalAlignment="Center"
Foreground="White"/>
</Border>
</Button.Content>
</Button>
</Grid>

On click event to part of an image WPF

I've got an iPhone image that I'd like to place a click event on the home button.
How can I accomplish this with WPF? I've tried placing a button on the image but I didn't get the desired result.
What type of control do you use for your image?
<Window.Background>
<ImageBrush ImageSource="Images/Skin/full.png" Stretch="Fill">
</ImageBrush>
</Window.Background>

You can place the image in a suitable panel like Canvas or Grid and use invisible buttons as overlay.
In resources:
<Style x:Key="InvisibleButtonStyle" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="Transparent" BorderBrush="Red" BorderThickness="1"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Usage:
<Grid Width="150" Height="150">
<ImageBrush ImageSource="Images/Skin/full.png" Stretch="Fill"/>
<Button x:Name="TopLeft" Margin="0,0,100,100" Click="TopLeft_Click" Style="{StaticResource InvisibleButtonStyle}"/>
<Button x:Name="TopRight" HorizontalAlignment="Right" Click="TopRight_Click" Margin="0,0,0,100" Width="100" Style="{StaticResource InvisibleButtonStyle}"/>
<Button x:Name="BottomLeft" VerticalAlignment="Bottom" Click="BottomLeft_Click" Margin="0,0,100,0" Height="100" Style="{StaticResource InvisibleButtonStyle}"/>
<Button x:Name="BottomRight" HorizontalAlignment="Right" VerticalAlignment="Bottom" Click="BottomRight_Click" Margin="0,0,0,0" Width="100" Height="100" Style="{StaticResource InvisibleButtonStyle}"/>
</Grid>
Note I added a red border to the transparent button in order to highlight the clickable areas, in reality it would only be transparent background.

I've achieved this by doing the following:
<Canvas Height="30" VerticalAlignment="Top" Margin="0,394,0,0" Width="220">
<Button Content="" Canvas.Left="102" Canvas.Top="6" Background="Transparent" Width="16" BorderBrush="Transparent" Cursor="Hand" >
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Transparent"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</Canvas>
Just have to set your margins and Canvas left and top positions to overlay the clickable area.

Since you need a part of image to be clickable, I would suggest this solution.
C/P from link...
<Canvas>
<Image Source="background.png"/>
<Ellipse Canvas.Left="82" Canvas.Top="88" Width="442" Height="216" Fill="Transparent" Cursor="Hand" MouseDown="Ellipse_MouseDown_1"/>
<Ellipse Canvas.Left="305" Canvas.Top="309" Width="100" Height="50" Fill="Transparent" Cursor="Hand" MouseDown="Ellipse_MouseDown_2"/>
</Canvas>

Making a WPF combobox with rounded corners

In my application, I need to make the combobox that I am using have rounded corners. I started with the XAML posted in the answer to this question and have made some modifications. I decided I didn't like the way that one looked as much, so I tried to style it and make it look a bit more like the default combobox. Now my combobox looks like this: ,
and when dropped down:
The issue is that when the user places their mouse over the combobox, it looks like this: . If I use Snoop, I can see this info:
It says
that the value of that border background is being set to "#FFBEE6FD", which is the color that shows when the mouse is over the combobox. The value source is "ParentTemplateTrigger". My issue is that I don't know where this border is coming from or why it's getting that value. I have tried to add template triggers with setters to set the background to white, but I don't know where to set the value for this mysterious border.
Here is the XAML for my ComboBox:
<ComboBox x:Name="ScanSizesComboBox"
Style="{StaticResource roundedCornersComboBox}"
Grid.ZIndex="4"
ItemsSource="{Binding ScanSizes}"
SelectedItem="{Binding SelectedScanSize, Mode=TwoWay}"
ToolTip="{Binding (Validation.Errors)[0].ErrorContent}"
Margin="0,10,89,0"
HorizontalAlignment="Right"
Width="61"
Height="26"
VerticalAlignment="Top"
Grid.Row="4">
</ComboBox>
And here is the style:
<Style x:Key="ComboBoxTextBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Border Name="ComboBoxTextBoxStyleBorder" CornerRadius="2"
BorderThickness="0,1,0,1"
Margin="0,0,1,1"
Background="{TemplateBinding Background}">
<Border.Style>
<Style TargetType="Border">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="White"/>
</Trigger>

</Style>
Ultimately, I would like for the user to be able to place his/her mouse over the combobox, and have it just look the same as it does when it is not highlighted. Any help is appreciated. Thanks.

Continuing from our comments conversation (which generally SO tries to avoid so much noise) this may get on you track.
So if I grab just all the template stuff to a bare bones basic default ComboBox and ComboBoxItem from a fresh WPF app, this is the output. Granted you won't need all of it, but it should ensure to an extent all expected functionality and DOM parts are here for reference so you have all the stuff like Triggers, Template Binding pieces etc, all available.
Notice the various Border and Rectangle elements in the various parts that would need to be altered in order to achieve the rounding of everything. I can't however provide any insight into how it would effect anything with MahApps as my experience with that is pretty limited since I've always just made my own stuff to accomplish what it essentially does.
Hope it helps. It's too long for SO's submission requirements though so here's the PasteBin link.

Button Hover Override

I have a button, as such:
<Button HorizontalAlignment="Left" Margin="0,55,0,0" VerticalAlignment="Top" Width="350" Click="StartProcedure_Click" BorderThickness="0" Height="60" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" HorizontalContentAlignment="Left" ScrollViewer.VerticalScrollBarVisibility="Disabled" VerticalContentAlignment="Center" Padding="10,1,0,0" IsHitTestVisible="True">
<StackPanel Orientation="Horizontal">
<Image Source="resources\img_xraystarticon.png" Width="50" Height="50"/>
<TextBlock TextElement.Foreground="#6a6869" Padding="5,0,0,0" VerticalAlignment="Center" FontSize="30" FontFamily="Century Gothic">Start Procedure</TextBlock>
</StackPanel>
<Button.Background>
<ImageBrush ImageSource="resources\img_emptyrectbutton.png"/>
</Button.Background>
</Button>
Where I applied the Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" style to remove the mouseover effects defaulting with the Button. However, I still continue to experience a mouseover effect, as shown here:
Prior to Mouseover, and with Mouseover:
I have attempted to override the MouseEnter event with no success (I have confirmed my MouseEnter event is triggered but I can't seem to negate the property that is set with MouseEnter by default with the above).
What do I need to do to avoid the above?
Thanks!
EDIT:
I have entered the below code but I am now unable to get a MouseEnter function to execute properly (I want the text to change colors but I am not seeing it happen):
<Button Name="Button_StartMenu" HorizontalAlignment="Left" Margin="0,55,0,0" VerticalAlignment="Top" Width="350" Click="StartProcedure_Click" BorderThickness="0" Height="60" HorizontalContentAlignment="Left" ScrollViewer.VerticalScrollBarVisibility="Disabled" VerticalContentAlignment="Center" Padding="10,1,0,0" IsHitTestVisible="True" MouseEnter="Button_MouseEnter">

</StackPanel>
</Button>

Instead of trying to 'prevent' it I would define the mouseover event to display the same as the non-mouseover. You can set them both to be the same and while it will still switch, visually it appears the same.
How do you change Background for a Button MouseOver in WPF?
<Button.Style>
<Style TargetType="Button">
<Setter Property="Background" Value="Green"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Green"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>

C# multiple contentpresenter on a button style (windows 8.1)

I'm trying to display 2 data on a button, using custom style.
So, I wrote an XAML code like below, with one 'ContentPresenter.'
<Style x:Key="Num_of_Comments" TargetType="Button">
<Setter Property="Foreground" Value="{ThemeResource AppBarItemForegroundThemeBrush}"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
<Setter Property="FontWeight" Value="Normal"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="Transparent" x:Name="RootGrid">
<Grid
Height="42"
Width="42">
<Ellipse
x:Name="Ellipse"
Fill="{ThemeResource AppBarItemBackgroundThemeBrush}"
Stroke="{TemplateBinding Foreground}"
StrokeThickness="2"
UseLayoutRounding="False" />
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="21"/>
<RowDefinition Height="21"/>
</Grid.RowDefinitions>
<ContentPresenter
Grid.Row="0"
Foreground="{TemplateBinding Foreground}"
HorizontalAlignment="Center"
VerticalAlignment="Center">
</ContentPresenter>
</Grid>
</Grid>
<Rectangle x:Name="FocusVisualWhite" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="1.5" StrokeEndLineCap="Square" Stroke="{ThemeResource FocusVisualWhiteStrokeThemeBrush}" StrokeDashArray="1,1"/>
<Rectangle x:Name="FocusVisualBlack" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="0.5" StrokeEndLineCap="Square" Stroke="{ThemeResource FocusVisualBlackStrokeThemeBrush}" StrokeDashArray="1,1"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And I use this style like this.
<Button Grid.Column="1" Content="{Binding Comments}" Style="{StaticResource Num_of_Comments}" IsEnabled="False" Margin="10,0,0,0" VerticalAlignment="Center" Foreground="{Binding Comments_color}"/>
Then, this button looks like this
Original button
Anyway, I'd like to add one more 'ContentPresenter' in the style, and display one more different data on the button.
But if I add one more 'ContentPresenter' into the style, I don't know how to assign 2 different data on each 'ContentPresenter.'
This is the button what I want to make.
The button I want to make
Thanks in advance

You can use Tag property on button to assign additional data and bind the second ContentPresenter Content as follows:
<ContentPresenter
Grid.Row="1"
Content="{TemplateBinding Tag}"
HorizontalAlignment="Center"
VerticalAlignment="Center">
</ContentPresenter>
and on Button:
<Button Tag="{Binding OTHERDATAPROPERTY}" Content="{Binding Comments}"></Button>
