C# WPF MouseEnter 및 MouseLeave on Grid

Question

2 개의 MouseEvent를 만들었지 만 문제는 그것이 내가 예상 한 것처럼 작동하지 않는다는 것입니다. 내 마우스 포인터가 Grid Space에서 오른쪽 일 때이 2 개의 이벤트가 활성화되어 있어야하지만 포인터가 모든 라인에있는 경우에만 작동합니다.

내 코드 : 투명로 그리드의 배경색을 설정

  // Grid 3 Rows. 
     Grid grid_Edit = new Grid(); 
     Grid.SetRow(grid_Edit, 0); 
     Grid.SetColumn(grid_Edit, 1); 
     RowDefinition rowDef1 = new RowDefinition(); 
     RowDefinition rowDef2 = new RowDefinition(); 
     RowDefinition rowDef3 = new RowDefinition(); 
     grid_Edit.RowDefinitions.Add(rowDef1); 
     grid_Edit.RowDefinitions.Add(rowDef2); 
     grid_Edit.RowDefinitions.Add(rowDef3); 
     grid_Edit.RowDefinitions[0].Height = new GridLength(1, GridUnitType.Star); 
     grid_Edit.RowDefinitions[1].Height = new GridLength(1, GridUnitType.Star); 
     grid_Edit.RowDefinitions[2].Height = new GridLength(1, GridUnitType.Star); 
     grid_Edit.MouseEnter += new MouseEventHandler(gridEdit_MouseEnter); 
     grid_Edit.MouseLeave += new MouseEventHandler(gridEdit_MouseLeave); 
     mainWindow_ref.Children.Add(grid_Edit); 

     // 3 lines 
     line1.Stroke = Brushes.White; 
     line1.X1 = 1; 
     line1.Stretch = Stretch.Fill; 
     Grid.SetRow(line1, 0); 
     line1.VerticalAlignment = VerticalAlignment.Center; 

     line2.Stroke = Brushes.White; 
     line2.X1 = 1; 
     line2.Stretch = Stretch.Fill; 
     Grid.SetRow(line2, 1); 
     line2.VerticalAlignment = VerticalAlignment.Center; 

     line3.Stroke = Brushes.White; 
     line3.X1 = 1; 
     line3.Stretch = Stretch.Fill; 
     Grid.SetRow(line3, 2); 
     line3.VerticalAlignment = VerticalAlignment.Center; 

     // add lines to grid_Edit 
     grid_Edit.Children.Add(line1); 
     grid_Edit.Children.Add(line2); 
     grid_Edit.Children.Add(line3); 



    private static void gridEdit_MouseLeave(object sender, MouseEventArgs e) 
    { 
     line1.Stroke = Brushes.White; 
     line2.Stroke = Brushes.White; 
     line3.Stroke = Brushes.White; 
    } 

    private static void gridEdit_MouseEnter(object sender, MouseEventArgs e) 
    { 
     line1.Stroke = Brushes.Black; 
     line2.Stroke = Brushes.Black; 
     line3.Stroke = Brushes.Black; 
    }

,이 그리드는 마우스 이벤트를 캡처 할 수 있습니다.
