how can I change the background of marked element(part of toolbar, in xaml)?
<ToolBar Grid.Column="1" x:Name="AdditionalModuleButtonsStackPanel" Background="{x:Null}"/>
I do not even know how that element is called. I need to make that background transparent.
According to this answer,
The overflow button unfortunately has a fixed background.
That means you must supply the entire template. Here is the style of the toolbar (long I know...), make sure to include it in your XAML (I added it to my Window.Resources):

Then you add the style by doing something like this:
<Grid>
<ToolBar x:Name="AdditionalModuleButtonsStackPanel" Background="{x:Null}" Style="{DynamicResource ToolBarStyle1}" />
</Grid>

I'm using a checkbox control like this:
<CheckBox VerticalAlignment="Bottom" IsChecked="{Binding Selected}"
Grid.Column="0"
FontSize="{StaticResource PhoneFontSizeLarge}"
Content="{Binding Name}">
</CheckBox>
The thing is that I change size to be a little bigger. In this case text is getting bigger, but tick itself remains the same. It looks ugly, can I resize checkbox somehow?
UPDATE
I'm doing it on windows phone so LayoutTransform not appropriate here
Try some thing like this:-
<CheckBox>
<CheckBox.LayoutTransform>
<ScaleTransform ScaleX="2" ScaleY="2" />
</CheckBox.LayoutTransform>
</CheckBox>
You can also check this link
<StackPanel Height="80"
Name="StackPanel1"
Orientation="Horizontal">
<Viewbox Height="{Binding Path=ActualHeight, ElementName=StackPanel1}">
<CheckBox />
</Viewbox>
</StackPanel>
Adjust the StackPanel height as needed.
Ended up with the following:
Add an empty checkbox
Open control in expression blend
Select checkbox there
Open Edit Template -> Edit Copy
It will create a new style with custom template that you will be able to assign to checkboxes.
It produced about 150 loc style, but I couldn't find another way
ScaleTransform scale = new ScaleTransform(2.0, 2.0);
yourCheckBox.RenderTransformOrigin = new Point(0.5, 0.5);
yourCheckBox.RenderTransform = scale;
Just add below mention codes in windows/usercontrol resource, it will automatically increase the default size of the []checkbox inside a Xaml control.

I have a C# application with a tick checkmark when user select the checkbox. The default color is black and not set by anyone. I would like to know the best approach to use to change the color of the checkmark, say to red instead of black.
I can't seem to find which part of the code is responsible for the color change. Tried finding resources online but it requires writing over hundred of lines of XAML just to set the color.
Any suggestion please.

I understand that you want to avoid writing over hundered of lines of XAML just to set the color, but from Visual Studio 2012 onwards, there's a feature where you can edit a copy of the control template. In Design mode, right click on the checkbox control, select Edit Template > Edit A Copy...
Then you can set where to define the template at, so you could either reuse it or just use it for one checkbox.
These are the colors you need to manipulate if you're on Windows 8 or above since the template varies base on Windows version. (The generated template has the following code)
<CheckBox.Resources>
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>

Hi I'm using XAML and C# to create a simple WPF demo. I want to toggle the visibility of just the arrow button of the expander. I've edited a custom template for the expander as seen below in the xaml code. I know I have to change the visibility of the ellipse and path.

I have a GridViewColumn with a HeaderTemplate that has an Image and a TextBlock. When the user hovers over the Image I am changing its opacity, but I am still getting the default header mouse over effect. How can I suppress this effect when the user hovers over the image?
The IsMouseOver Trigger is located inside the GridViewColumnHeader template. It looks like this
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="HeaderBorder" Value="{StaticResource GridViewColumnHeaderHoverBackground}"/>
<Setter Property="BorderBrush" TargetName="HeaderHoverBorder" Value="#FF88CBEB"/>
<Setter Property="Visibility" TargetName="UpperHighlight" Value="Visible"/>
<Setter Property="Background" TargetName="PART_HeaderGripper" Value="Transparent"/>
</Trigger>
Update
With a little code behind you can disable the IsMouseOver trigger in the Loaded event for GridViewColumnHeader. It's overriding the setters in the trigger by setting their values and this will work for the classic theme as well.
<ListView ...>
<ListView.Resources>
<Style TargetType="{x:Type GridViewColumnHeader}">
<EventSetter Event="Loaded" Handler="GridViewColumnHeader_Loaded"/>
</Style>
</ListView.Resources>
<!--...-->
</ListView>
Code behind event handler
private void GridViewColumnHeader_Loaded(object sender, RoutedEventArgs e)
{
GridViewColumnHeader columnHeader = sender as GridViewColumnHeader;
Border HeaderBorder = columnHeader.Template.FindName("HeaderBorder", columnHeader) as Border;
if (HeaderBorder != null)
{
HeaderBorder.Background = HeaderBorder.Background;
}
Border HeaderHoverBorder = columnHeader.Template.FindName("HeaderHoverBorder", columnHeader) as Border;
if (HeaderHoverBorder != null)
{
HeaderHoverBorder.BorderBrush = HeaderHoverBorder.BorderBrush;
}
Rectangle UpperHighlight = columnHeader.Template.FindName("UpperHighlight", columnHeader) as Rectangle;
if (UpperHighlight != null)
{
