The goal is to indicate InputSimulator.SimulateMouseMoveEvent to user. So, i need to get coursor position on document on every move event, iam using EventListener with DOMEventType.OnMouseMove. But can`t get if DOMEventArgs contains MouseEvent properties?

Is it posible to do my way at all? Is there are any solutions to do this?

For the described purpose you need to subscribe to the mentioned event on the JavaScript side and uses the JS-.NET bridge.

This code sample demonstrates how to obtain the mouse position with the mousemove event: XAML

<Window x:Class="WpfApplication33.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:wpf="clr-namespace:DotNetBrowser.WPF;assembly=DotNetBrowser"
        xmlns:local="clr-namespace:WpfApplication33"
        mc:Ignorable="d"
        Title="MainWindow" Height="600" Width="900">
    <Grid Name="mainLayout">
        <Grid.RowDefinitions>
            <RowDefinition Height="24*"/>
            <RowDefinition Height="295*"/>
        </Grid.RowDefinitions>
        <Button x:Name="button" Content="Button" Grid.Row="0" Click="button_Click"/>
        <wpf:WPFBrowserView Name="browserView" Grid.Row="1"/>
    </Grid>
</Window>

C#

using System;
using System.Diagnostics;
using System.Windows;
using DotNetBrowser;
using DotNetBrowser.DOM;
using DotNetBrowser.DOM.Events;

namespace WpfApplication33
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            browserView.Browser.FinishLoadingFrameEvent += (s, e) =>
            {
                if(e.IsMainFrame)
                {
                    JSValue window = e.Browser.ExecuteJavaScriptAndReturnValue("window");
                    window.AsObject().SetProperty("CoordinatesObject", new CoordinatesObject());


                    //This code only notified that the onmousemove event was fired.
                    //It can't return the current mouse position.
                    //    DOMDocument document = browserView.Browser.GetDocument();
                    //    DOMElement documentElement = document.DocumentElement;
                    //    DOMEventHandler eventHandler = (sender, args) =>
                    //    {
                    //        Debug.WriteLine("OnMouseMove Fired");
                    //    };
                    //    documentElement.AddEventListener(DOMEventType.OnMouseMove, eventHandler, false);
                }
            };

            browserView.Browser.ScriptContextCreated += (sender, args) =>
            {
                args.Browser.ExecuteJavaScript(@"
                        document.onmousemove = getMouseXY;
                        function getMouseXY(e) {
                        CoordinatesObject.MousePosition(e.pageX, e.pageY);
                        }");
            };
            browserView.Browser.LoadURL("google.com");
        }

        private void button_Click(object sender, RoutedEventArgs e)
        {
            browserView.InputSimulator.SimulateMouseMoveEvent(200, 150);
        }
    }

    internal class CoordinatesObject
    {
        public void MousePosition(int X, int Y)
        {
            Debug.WriteLine("X=" + X + " Y=" + Y);
        }
    }
}
