WPF: The Simplest Way to Get the Default Template of a Control as XAML
Every WPF Developer has probably faced this issue before. You want to change the default template of a control and need it in XAML. Where can you get the default template? There are multiple ways:
- Find the correct MSDN page for your framework version
- Use a tool
- Use Expression Blend
In my opinion, none of these solutions is very convenient. I always end up either not finding the correct version, not having blend installed, etc…
Alas, there is a much easier way. You can use the XamlWriter class to serialize the default template of your control:
1 public static void SaveDefaultTemplate() 2 { 3 var control = Application.Current.FindResource(typeof(ProgressBar)); 4 using (XmlTextWriter writer = new XmlTextWriter(@"defaultTemplate.xml", System.Text.Encoding.UTF8)) 5 { 6 writer.Formatting = Formatting.Indented; 7 XamlWriter.Save(control, writer); 8 } 9 }
This will produce the following file for the ProgressBar in the sample code:
1 <Style TargetType="Button" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib">
