[DevExpress控件应用]XtraGrid: 改变当前单元格外框的颜色

代码：

using DevExpress.Utils.Paint;

    public class CustomXPaint : XPaint
    ...{
        public override void DrawFocusRectangle(Graphics g, Rectangle rect, Color foreColor, Color backColor)
        ...{
            if (CanDraw(rect) == false)
                return;
            Brush brush = Brushes.Red;    //红色外框
            g.FillRectangle(brush, new Rectangle(rect.X, rect.Y, 1, rect.Height - 1));          // left
            g.FillRectangle(brush, new Rectangle(rect.X, rect.Y, rect.Width - 1, 1));           // top
            g.FillRectangle(brush, new Rectangle(rect.Right - 1, rect.Y, 1, rect.Height - 1));  // right
            g.FillRectangle(brush, new Rectangle(rect.X, rect.Bottom - 1, rect.Width, 1));      // bottom
        }
    }

    public partial class Form1 : Form
    ...{
        构造函数#region 构造函数
        public Form1()
        ...{
            InitializeComponent();
        }
        #endregion
        画面激活时#region 画面激活时
        void Form1_Activated(object sender, EventArgs e)
        ...{
            //设自定义边框    
            FieldInfo fi = typeof(XPaint).GetField("graphics", BindingFlags.Static | BindingFlags.NonPublic);
            fi.SetValue(null, new CustomXPaint());
        }
        #endregion
        画面非激活时#region 画面非激活时
        void Form1_Deactivate(object sender, EventArgs e)
        ...{
            //恢复原样
            FieldInfo fi = typeof(XPaint).GetField("graphics", BindingFlags.Static | BindingFlags.NonPublic);
            fi.SetValue(null, new XPaint());
        }
        #endregion
    }

如果是只读的查询表格，可以添加如下的代码：

        画面加载时#region 画面加载时
        private void FormProjectBrowser_Load(object sender, EventArgs e)
        ...{
        gridView1.OptionsBehavior.Editable = false;
            gridView1.OptionsCustomization.AllowFilter = false;
            gridView1.OptionsSelection.EnableAppearanceFocusedRow = true;
            gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;
            gridView1.FocusRectStyle = DrawFocusRectStyle.RowFocus;

            gridView1.Appearance.FocusedRow.BackColor = Color.PowderBlue;
            gridView1.Appearance.FocusedRow.ForeColor = Color.Red;
            //gridView1.Appearance.FocusedRow.Font = new Font(gridView1.Appearance.FocusedRow.Font, FontStyle.Bold);

            gridView1.Appearance.HideSelectionRow.Assign(gridView1.Appearance.FocusedRow);

        //...
        }

 

达到行选择的效果。(效果图上传不了)
