Namespace: DevExpress.Mvvm.UI

Assembly: DevExpress.Xpf.Core.v23.1.dll

NuGet Package: DevExpress.Wpf.Core


public IEventArgsConverter EventArgsConverter { get; set; }

Property Value

Type Description

An object that implements the IEventArgsConverter interface.


The EventToCommand behavior allows you to pass an event’s arguments to a command. If you want to maintain the clean MVVM pattern and convert the event’s arguments to an object suitable for the command, specify the EventArgsConverter property as follows:

<ListBox x:Name="list">
        <dxmvvm:EventToCommand EventName="MouseDoubleClick" Command="{Binding EditCommand}" EventArgsConverter="{dxmvvm:ItemsControlMouseEventArgsConverter}"/>

The defined EventArgsConverter should implement the IEventArgsConverter interface. You can also derive the converter from the EventArgsConverterBase<TArgs> class, which already implements the IEventArgsConverter interface.

public interface IEventArgsConverter {
    object Convert(object sender, object args);
public abstract class EventArgsConverterBase<TArgs> : IEventArgsConverter {
    protected EventArgsConverterBase();
    protected abstract object Convert(object sender, TArgs args);

A parameter that a command processes may indicate to the source object how to implement a certain action. You can pass the parameter from the command to the bound event, so that the source object can determine how to proceed. Create a converter class that implements IEventArgsTwoWayConverter and assign the class object to the EventArgsConverter property.
