Apparantly when users right-click in our WPF application, and they use the Windows Classic theme, the default ContextMenu of the TextBox (which contains Copy, Cut and Paste) has a black background.
I know this works well:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<TextBox ContextMenu="{x:Null}"/>
</Page>
But this doesn't work:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Page.Resources>
<Style x:Key="{x:Type TextBox}" TargetType="{x:Type TextBox}">
<Setter Property="ContextMenu" Value="{x:Null}"/>
</Style>
</Page.Resources>
<TextBox/>
</Page>
Does anyone know how to style or disable the default ContextMenu for all TextBoxes in WPF?

This is way is what I always use:
<TextBox x:Name="MyTextbox">
<TextBox.ContextMenu>
<ContextMenu Visibility="Hidden"/>
</TextBox.ContextMenu>
</TextBox>
And also can use:
MyTextbox.ContextMenu.Visibility = Visibility.Hidden;
MyTextbox.ContextMenu.Visibility = Visibility.Visble;

Doesn't matter, if you do not provide a key, it will use the TargetType
as key just the same way my example uses :)
Taken from MSDN on Style:
Setting the
TargetType
property to theTextBlock
type without setting anx:Key
implicitly sets thex:Key
to{x:Type TextBlock}
. This also means that if you > > give the above Style anx:Key
value of anything other than{x:Type TextBlock}
, the Style would not be applied to all TextBlock elements automatically. Instead, you need to apply the style to theTextBlock
elements explicitly.

Bizarre. ContextMenu="{x:Null}"
doesn't do the trick.
This does, however:
<TextBox.ContextMenu>
<ContextMenu Visibility="Collapsed">
</ContextMenu>
</TextBox.ContextMenu>

Due to a late bug report we discovered that we cannot use the ApplicationComands Cut Paste and Copy directly in a partial trusted application. Therefor, using these commands in any Commmand of your controls will do absolutely nothing when executed.
So in essence Brads answer was almost there, it sure looked the right way i.e. no black background, but did not fix the problem.
We decided to "remove" the menu based on Brads answer, like so:
<ContextMenu x:Key="TextBoxContextMenu" Width="0" Height="0" />
And use this empty context menu like so:
<Style TargetType="{x:Type TextBox}">
<Setter Property="ContextMenu" Value="{StaticResource TextBoxContextMenu}" />
</Style>

To style ContextMenu's for all TextBoxes, I would do something like the following:
First, in the resources section, add a ContextMenu which you plan to use as your standard ContextMenu in a textbox.
e.g.
<ContextMenu x:Key="TextBoxContextMenu" Background="White">
<MenuItem Command="ApplicationCommands.Copy" />
<MenuItem Command="ApplicationCommands.Cut" />
<MenuItem Command="ApplicationCommands.Paste" />
</ContextMenu>
Secondly, create a style for your TextBoxes, which uses the context menu resource:
<Style TargetType="{x:Type TextBox}">
<Setter Property="ContextMenu" Value="{StaticResource TextBoxContextMenu}" />
</Style>
Finally, use your text box as normal:
<TextBox />
If instead you want to apply this context menu to only some of your textboxes, do not create the style above, and add the following to your TextBox markup:
<TextBox ContextMenu="{StaticResource TextBoxContextMenu}" />
Hope this helps!

Try removing the x:Key attribute from the Style resource, leaving TargetType. I know, you're supposed to have that x:Key for a resource, but if you have it along with your TargetType the Key prevails.
Here's a sample style that I use in a project to skin all tooltips in one of my apps (this is in App.Resources--notice, no Key)
<Style
TargetType="{x:Type ToolTip}">
<Setter
Property="Template">
<Setter.Value>
<ControlTemplate
TargetType="{x:Type ToolTip}">
<Grid
Width="{TemplateBinding Width}"
Height="{TemplateBinding Height}">
<Rectangle
RadiusX="9"
RadiusY="9"
Stroke="LightGray"
StrokeThickness="2">
<Rectangle.Fill>
<RadialGradientBrush>
<GradientStop />
<GradientStop
Color="FloralWhite"
Offset="0" />
<GradientStop
Color="Cornsilk"
Offset="2" />
</RadialGradientBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter
Margin="6 4 6 4" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
