gridcontrol 添加行删除行

一、添加行

       注意，必须先绑定数据源（可以是一个空的Datatable）；然后再执行添加行的动作，否则不会成功；

 

    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
            this.gridView1.InitNewRow += gridView1_InitNewRow;
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            //设置数据结构
            DataTable dt = new DataTable();
            dt.Columns.Add("GCol1", Type.GetType("System.String"));
            dt.Columns.Add("GCol2", Type.GetType("System.String"));
            //必须有此行代码，绑定数据源，否则gridView1添加不了数据行
            this.gridControl1.DataSource = dt;
        }

        /// <summary>
        /// 添加行 执行动态绑定数据
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
        {
            DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView;
            view.SetRowCellValue(e.RowHandle, view.Columns["GCol1"], "123"+DateTime.Now.ToString("HHmmss"));
            view.SetRowCellValue(e.RowHandle, view.Columns["GCol2"], "456" + DateTime.Now.ToString("HHmmss"));
        }
        /// <summary>
        /// 事件：添加按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button1_Click(object sender, EventArgs e)
        {
            //添加一行的命令
            this.gridView1.AddNewRow();
        }
    }
