Can a link be set on a drive parameter?
My understanding is: ‘ConverterParameter is not a dependency property and is not bindable’. {“Cannot set a ‘Binding’ on property ‘ConverterParameter’ of type ‘Binding’. A ‘Binding’ can only be set on a DependencyProperty of a DependencyObject.”}

How to associate a custom value converter with a link?
If you want to associate a custom value converter with a binding, you must create a class that implements the IValueConverter interface and provides implementations for the Convert and ConvertBack methods.
How are value converters used in WPF data binding?
Value converters are classes that implement the IValueConverter interface. This interface includes two methods. Convert is used to transform a source value to a suitable type for the target dependency property. ConvertBack reverses the process. Usually you will implement both.
How does the interaction between the data binding and the value converter work?
Since the Text DP is found first, it will try to set its value first, and the DataContext is not set to the TextBlock yet, so it will inherit from its parent window whose DataContext is set to the MainWindowViewModel. So you will see the MainWindowViewModel printed to your converter.
Can you bind the width to a converter parameter in Java?
Width is a dependency property. So you can bind the width to a converter parameter. Something like that, anyway. I hope that helps. My understanding is: ‘ConverterParameter is not a dependency property and is not bindable’.
Can a link be the target object of another link?
Since Binding does not derive from DependencyObject, none of its properties can be a dependency property. As a consequence, a Binding can never be the target object of another Binding. However, there is an alternative solution. You could use a MultiBinding with a multivalue converter instead of a normal Binding:
Why is the converter parameter not a dependency property?
I simply need to send the Label of the top level parent and the Label of the control itself to my converter class. The ConverterParameter property cannot be bound because it is not a dependency property. Since Binding does not derive from DependencyObject, none of its properties can be a dependency property.
Why does the trigger not work on the converter?
The converter looks fine, however the activator is not applied for some reason. You must set the Foreground property in your style to change it dynamically at runtime. If you are trying to change the property value dynamically, the corresponding property should be held only in the Setter tag.
Can a link be set on a dependency?
A ‘Binding’ can only be set on a DependencyProperty of a DependencyObject.”} Lead Software Engineer:…
How do you set the listview.itemtemplate property in XAML?
The ListView.ItemTemplate property can also be set on a DataTemplate that is created from a cell type. The advantage of this approach is that the appearance defined by the cell type can be reused by multiple data templates throughout the application. The following XAML shows an example of this approach:
How do you create a data template in C#?
In C#, a DataTemplate is created using a constructor overload that specifies the cell type as an argument. The cell type must derive from the ViewCell type, as shown in the following code example:
How to link a linked object to a converter?
If you still want to follow the path of the converter, pass the entire bound object to the converter and then you can do your calculation that way. Another option is to get fancy by creating a custom converter that wraps your other converter and passes a converter parameter of a property.
When to use ivalueconverter in WPF Scott Logic?
This post provides a simple implementation of IValueConverter that makes use of framework type converters to convert between a wide range of source/target types. This converter can be used both within bindings and in the code behind to provide more concise property setters.
How does calcbinding support static properties in the binding expression?
As of version 2.3, CalcBinding supports static properties on the binding expression. You can write routes that start with the static property of any class and have any number of properties after the static property. CalcBinding uses the following static property path declaration syntax: ‘xmlNamespace:Class.StaticProperty.NestedProperty’, etc.
How to create an interceptor method in Java?
The javax.interceptor.AroundConstruct annotation designates the method as an interceptor method that stands in the way of invoking the target class’s constructor. The javax.annotation.PostConstruct annotation is used to designate a method as an interceptor for post-construction lifecycle events.
How are converters used in the link engine?
Commonly used converters that allow data to be modified as it passes through the binding engine. Converts a boolean value to an object. The converted value is selected from the values of the TrueValue and FalseValue properties
How is data shared in a chain of interceptors?
Data can be shared between interceptors. The same InvocationContext instance is passed as an input parameter to each interceptor method in the chain of interceptors for a particular target method. The contextData property of the InvocationContext instance is used to pass data through interceptor methods.
How to avoid memory leaks when using data binding and view binding?
LeakCanary tells us that our binding keeps a reference to our view ( mRoot) after the Fragment’s onDestroyView() has been called and this could cause a memory leak. When it comes to View Binding, Google’s own docs are teaching us how to do it the right way to avoid memory leaks:
