I'm trying to replace the checkmark of the standard WPF checkbox by my own checkmark (actually a Path). The checkbox should look like the standard one.
Where can I find the Microsoft xaml template of the checkbox, so I could modify it in the xaml? Or is there an more elegant way of doing this?
Note: I found already a template on MSDN ( http://msdn.microsoft.com/en-us/library/ms752319%28v=vs.110%29.aspx ), but it looks completely different.

The linked template is simply some random template. It's not default CheckBox template.
You can easily extract templates yourself (see here for a full source, the page is in Russian, but code with English comments):
// get all control types
Type typeControl = typeof(Control);
List<Type> myTypes = new List<Type>();
Assembly assembly = Assembly.GetAssembly(typeof(Control));
foreach (Type type in assembly.GetTypes())
{
if (type.IsSubclassOf(typeControl) && !type.IsAbstract && type.IsPublic)
myTypes.Add(type);
}
Then for any specific type
// Instantiate the type.
ConstructorInfo info = type.GetConstructor(System.Type.EmptyTypes);
Control control = (Control)info.Invoke(null);
// Get the template.
ControlTemplate template = control.Template;
// Get the XAML for the template.
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb, settings);
XamlWriter.Save(template, writer);
// Display the template.
someControl.Text = sb.ToString();
Here is my CheckBox template:
<?xml version="1.0" encoding="utf-16"?>

There are tools that extract the original XAML templates from System.Windows.Controls but ultimately, it's down to you as Microsoft as far as I know provide that anywhere. You will need to redefine the entire CheckBox template to achieve what you want.
There are a few websites that list the reflected source code for the .NET Framework assemblies that you could try for an original "generic.xaml" file.
Step1 : Please Open New Project and Write Down Checkbox tag.
Designer View will look
Step 2: In Designer view ----Right click on CheckBox ->Edit Template->Edit A Copy
Step 3: Give name to style ->select resource window/checkobx ->ok
and Finally you can change/replace path by changing path in x:Name="markGrid"
