Getting rid of borders in GridView, WPF/WinForms issues

[ris-work]

Expected Behavior

The borders are gone.

Actual Behavior

The borders are still there. I don't know what those black and white boxes are.
I even tried setting WPF GridView's border brush to transparent. Didn't work.
What are those? On WinForms, I am unable to style the selected row, but the borders aren't there.

Steps to Reproduce the Problem

Create a GridView.
Load it up with random entries.

Code that Demonstrates the Problem

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Eto.Forms;
using Eto;
using System.IO;

namespace HealthMonitorLogViewer
{
    public class NavigableListFormMinimal: Form
    {
        public NavigableListFormMinimal()
        {
            GridView LB = new GridView() { ShowHeader = false, GridLines = GridLines.None };
            LB.Size = new Eto.Drawing.Size(200, 600);
            LB.Columns.Add(new GridColumn() { HeaderText = "Navigate to...", DataCell = new TextBoxCell(0){ } });
            LB.BackgroundColor = Eto.Drawing.Colors.Black;
            //LB.TextColor = Eto.Drawing.Colors.White;
            //LB.Font = new Eto.Drawing.Font("Courier", 18);
            
            Panel CurrentPanel = new Panel();
            
            var loadOncePanels = new List<string>() {
                "Network Stats Panel",
                "Network Stats Panel 2",
                "Network Stats Panel 3",
                "Network Stats Panel 4"
            };
            LB.DataStore = loadOncePanels.Select(x => new List<string>() { x  }).ToList();
            Content = new StackLayout(new StackLayoutItem(LB), new StackLayoutItem(CurrentPanel)) { Orientation = Orientation.Horizontal, Spacing = 10 };
            LB.GridLines = GridLines.None;

            LB.CellFormatting += (e, a) => {
                if (a.Row == LB.SelectedRow)
                {
                    a.ForegroundColor = Eto.Drawing.Colors.Black;
                    a.BackgroundColor = Eto.Drawing.Colors.White;
                    
                }
                else
                {
                    a.ForegroundColor = Eto.Drawing.Colors.Wheat;
                    a.BackgroundColor = Eto.Drawing.Colors.Black;
                }
                a.Font = new Eto.Drawing.Font("Segoe UI", 10, Eto.Drawing.FontStyle.Bold, Eto.Drawing.FontDecoration.None);
            };
            BackgroundColor = Eto.Drawing.Colors.Black;
            Padding = 10;
        }
    }
}

Hi @ris-work

Have you tried the RowFormatting event instead? The CellFormatting only applies to the actual cell and not the row, and since the cells don't occupy the entire content of the row that color shows up.

As for the border, there's a Border property you can set to BorderType.None

Hope this helps
