wpf - How do I reset a DependencyProperty back to it's default value in XAML -


I am using a user-adjustable effect sliders and I have a reset button Slider's The idea is to allow users to reset the effect property as specified in the metadata to the default value of the property.

I think it might be trivial to do this in XML.

Dependency attributes are not actually the default values, if there is no local value in a dependency property It will receive the value of the property based on the success of the property either through the successor or fortune.

You actually have the local value of the property XAML - for which you will need to call ClearValue on the property, and there is no way to find the object and any method on this Call declaratively, but as long as the value of the property's property (instead of forcibly price) is being received, you can force the property by complying with the original property to the property,

For example, here's a style that you use to create a ListBox , which sets the foreground color of all the items Not is selected:

  & lt; ListBox.ItemContainerStyle & gt; & Lt; Style TargetType = "ListBoxItem" & gt; & Lt; Setter property = "foreground" value = "red" /> & Lt; Style.Triggers & gt; & Lt; Trigger Property = "Iceded" value = "true" & gt; & Lt; Setter Property = "Foreground" value = "{Compulsive Relative Soros = {ResultualSource SearchInter, Ancestor Type = List Box}, Path = Foreground}" /> & Lt; / Catalyst & gt; & Lt; /Style.Triggers> & Lt; / Style & gt; & Lt; /ListBox.ItemContainerStyle>  

It basically applies value inheritance through binding. This means that the ListBoxItem.Foreground property is now a local value, and whenever you change the property on Foreground on the ListBox It is compulsive to update ListBoxItem.Foreground and not dependency-asset system if you have hundreds of thousands of items in your ListBox It may be important but in most real-world cases, you will never pay attention to the difference.
