Я использовал найденный код здесь , перед которым элемент управления Grid
расширяется, чтобы включить свойства, которые позволяют указывать видимость, толщину и цвет GridLine
<local:GridEx ShowCustomGridLines="True"
GridLineBrush="#FF38B800"
GridLineThickness="2">
...
</local:GridEx>
В случае, если эта ссылка не работает, вот код:
public class GridControl : Grid
{
#region Properties
public bool ShowCustomGridLines
{
get { return (bool)GetValue(ShowCustomGridLinesProperty); }
set { SetValue(ShowCustomGridLinesProperty, value); }
}
public static readonly DependencyProperty ShowCustomGridLinesProperty =
DependencyProperty.Register("ShowCustomGridLines", typeof(bool), typeof(GridControl), new UIPropertyMetadata(false));
public Brush GridLineBrush
{
get { return (Brush)GetValue(GridLineBrushProperty); }
set { SetValue(GridLineBrushProperty, value); }
}
public static readonly DependencyProperty GridLineBrushProperty =
DependencyProperty.Register("GridLineBrush", typeof(Brush), typeof(GridControl), new UIPropertyMetadata(Brushes.Black));
public double GridLineThickness
{
get { return (double)GetValue(GridLineThicknessProperty); }
set { SetValue(GridLineThicknessProperty, value); }
}
public static readonly DependencyProperty GridLineThicknessProperty =
DependencyProperty.Register("GridLineThickness", typeof(double), typeof(GridControl), new UIPropertyMetadata(1.0));
#endregion
protected override void OnRender(DrawingContext dc)
{
if (ShowCustomGridLines)
{
foreach (var rowDefinition in RowDefinitions)
{
dc.DrawLine(new Pen(GridLineBrush, GridLineThickness), new Point(0, rowDefinition.Offset), new Point(ActualWidth, rowDefinition.Offset));
}
foreach (var columnDefinition in ColumnDefinitions)
{
dc.DrawLine(new Pen(GridLineBrush, GridLineThickness), new Point(columnDefinition.Offset, 0), new Point(columnDefinition.Offset, ActualHeight));
}
dc.DrawRectangle(Brushes.Transparent, new Pen(GridLineBrush, GridLineThickness), new Rect(0, 0, ActualWidth, ActualHeight));
}
base.OnRender(dc);
}
static GridControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(GridControl), new FrameworkPropertyMetadata(typeof(GridControl)));
}
}
