winform 的 datagridview 动态刷新

要实现在 datagridview 中动态的增删改查，目前能用的比较友好的方案似乎只有 datatable，网上有人说用 BindingList 的，我替你们试过了，无法筛选，坑很多

public partial class Form1 : Form
    {
        private DataTable dataTable = new DataTable();
        private BindingSource bindingSource;

        public Form1()
        {
            InitializeComponent();
            dataGridView1.AllowUserToAddRows = false;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            //创建自增列
            dataTable.Columns.Add(new DataColumn("Id", typeof(int)) { Caption = "ID", AutoIncrement = true, AutoIncrementSeed = 1 });

            //创建字符串列
            dataTable.Columns.Add(new DataColumn("Name", typeof(string)) { Caption = "姓名" });

            //创建一个数值列
            dataTable.Columns.Add(new DataColumn("Age", typeof(int)) { Caption = "年龄" });

            //创建一个object列
            dataTable.Columns.Add(new DataColumn("Data", typeof(object)) { Caption = "数据" });

            //添加一个计算列，由其它列数据生成
            dataTable.Columns.Add(new DataColumn("BirthYear", typeof(int), DateTime.Now.Year.ToString() + " - Age") { Caption = "出生年份" });

            //创建数据
            for (var i = 0; i < 10; i++)
            {
                var row = dataTable.NewRow();
                row["Name"] = "Name" + (i + 1).ToString();
                row["Age"] = i + 20;
                dataTable.Rows.Add(row);
            }

            bindingSource = new BindingSource();
            bindingSource.DataSource = new DataView(dataTable);
            dataGridView1.DataSource = bindingSource;

            //更新表头
            foreach (DataColumn column in dataTable.Columns)
            {
                string columnName = column.ColumnName;
                string columnCaption = column.Caption;

                //隐藏显示不同的列
                if (columnName == "Data")
                    column.ExtendedProperties["Visible"] = false;
                else
                    column.ExtendedProperties["Visible"] = true;

                dataGridView1.Columns[columnName].Visible = Convert.ToBoolean(column.ExtendedProperties["Visible"]);

                // 使用 Caption 属性作为列标题，如果 Caption 为空，则使用 ColumnName
                dataGridView1.Columns[columnName].HeaderText = string.IsNullOrEmpty(columnCaption) ? columnName : columnCaption;
            }
        }

        private void btnFilter_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrWhiteSpace(bindingSource.Filter))
                bindingSource.Filter = "Age > 25";
            else
                bindingSource.Filter = string.Empty;
        }

        private void btnAdd_Click(object sender, EventArgs e)
        {
            var i = dataTable.Rows.Count ;
            var row = dataTable.NewRow();
            row["Name"] = "Name" + (i + 1).ToString();
            row["Age"] = i + 20;
            dataTable.Rows.Add(row);
        }

        private void dataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
        {
            var column = dataGridView1.Columns[e.ColumnIndex];
            if (column.HeaderCell.Tag == null)
            {
                column.HeaderCell.Tag = 1;
                column.HeaderCell.SortGlyphDirection = SortOrder.Ascending;
            }
            else
            {
                column.HeaderCell.Tag = null;
                column.HeaderCell.SortGlyphDirection = SortOrder.Descending;
            }

            // 执行排序
            var direction = column.HeaderCell.SortGlyphDirection == SortOrder.Ascending ? ListSortDirection.Ascending : ListSortDirection.Descending;
            dataGridView1.Sort(column, direction);
        }

        private void btnDelete_Click(object sender, EventArgs e)
        {
            if (dataTable.Rows.Count > 0)
            {
                dataTable.Rows[0].Delete();
                dataTable.AcceptChanges();
            }
        }

        private void btnQuery_Click(object sender, EventArgs e)
        {
            DataRow[] rows = dataTable.Select("Age = 25");
            foreach (var row in rows)
            {
                Console.WriteLine("Name:" + row["Name"].ToString());
             }
        }
    }
