1、主要代码:

private void Form1_Load(object sender, EventArgs e)        {            DataTable dt = new DataTable();            dt.Columns.Add("A");            dt.Columns.Add("B");            for (int i = 0; i < 20; i++)            {                dt.Rows.Add(i + 1, "测试数据0000" + i);            }            gridControl1.DataSource = dt;                    }        private void txt_MouseUp(object sender, MouseEventArgs e)        {            TextEdit txt = gridView1.ActiveEditor as TextEdit;            int a = txt.SelectionStart;            MessageBox.Show("鼠标当前坐标"+a);        }
