DataTrigger Binding in WPF Style

Question

I have the following Button and Style in WPF and I need to generalize the Binding in the DataTrigger section because I have near 10 similar buttons in the same Window and ea

Answer 1

could you provide me an example of what you explained?

Sure,

1 - Using Tag

In your Style have your DataTrigger as:

  ...

as for usage:

2 - Using Attached Property:

"local:" refers to the xaml namespace alias of your application or if you use different namespaces, the namespace where MyCustomPropertyCollection is declared.

code-behind:

public class MyCustomPropertyCollection {
  public static readonly DependencyProperty SomeStringProperty =
    DependencyProperty.RegisterAttached(
      "SomeString",
      typeof(string),
      typeof(MyCustomPropertyCollection),
      new FrameworkPropertyMetadata(string.Empty));

  public static void SetSomeString(UIElement element, string value) {
    element.SetValue(SomeStringProperty, value);
  }

  public static string GetSomeString(UIElement element) {
    return (string)element.GetValue(SomeStringProperty);
  }
}

Style.DataTrigger

  ...

usage:

3 - Normal Dependency Property

custom Button class:

public class MyButton : Button {
  public static readonly DependencyProperty SomeStringProperty =
    DependencyProperty.Register(
      "SomeString",
      typeof(string),
      typeof(MyButton),
      new FrameworkPropertyMetadata(string.Empty));

  public string SomeString {
    get {
      return (string)GetValue(SomeStringProperty);
    }
    set {
      SetValue(SomeStringProperty, value);
    }
  }
}

Style in xaml not only needs DataTrigger updated but Style definition too.

so switch
