c# - WPF change background of a control with an attached property -

I need to change the background of the label and button when a boolean variable (the default color is returned to the wrong). So I have written an attached property so far this looks like this:

  public class BackgroundChanger: DependencyObject {#region dependency attribute // condition public static bool GetStatus (DependencyObject obj) {return (bool Obj.GetValue (StatusProperty); } Public static zero SetStatus (dependency object obj, boolean value) {obj.SetValue (StatusProperty, value); } Public static Read Only DependencyProperty StatusProperty = DependencyProperty.RegisterAttached ("status", typeof (bool), typeof (BackgroundChanger), new UIPropertyMetadata (incorrect, OnStatusChange)); #endregion Private Static Zero OnStatusChange (dependency object obj, DependencyPropertyChangedEventArgs e) {var element = obj; If (element! = Null) {if ((bool) e.NewValue) element.Background = Brushes.LimeGreen; Second element Background = default (brush); }}}  

And I use it like this:

This works fine when according to the variable test is set in viewmodel, background color changes for LimeGreen < P> My questions :.

Color LimeGreen is hard coded I would like to set that color (as well as the default color) in XML so that I can decide that two of the background Which two colors change between the colors How can I go about doing this?

You can have multiple attachments that are easy to access, go to static . and set. methods for which you supply the dependency object , which you want to assume an associated asset operated

  Public Square BackgroundChanger :. DependencyObject {// property brushes background // type "propdp", press "tab" and complete filling Private Static Zero OnStatusChange (DependencyObject obj, DependencyPropertyChangedEventArgs e) {Making var element = obj; If (element! = Null) {if ((bool) e.NewValue) element.Background = GetBrush (obj); // Another affiliate property value get other elements. Background = default (brush); }}}  

XAML will look like this
