操作另一窗体的变量事件

窗体间要相互传递数据时，比如在ERP系中常见单据流中的数据传递，可设计窗体中的数据变量的访问属性为public

/// <summary>
        /// 双击表格行穿透查询到单据
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            
            if (e.RowIndex > -1)
            {
                
                var voucherNo = this.dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();
                Frm_income frm_income = new Frm_income();
                string tabPageText = frm_income.Text;
                Utility.UI.EmbedForm embedForm = new Utility.UI.EmbedForm();
                //使用母窗体的属性信息，实现动态创建插入页签式窗体
                embedForm.openForm(frm_income, tabPageText, (TabControl)this.Parent.Parent.Parent.Controls["tabControl1"], (Panel)this.TopLevelControl.Controls["panel1"]);
                ToolStrip t = (ToolStrip)frm_income.Controls["ts_income"];
            
                frm_income.tsb_query.PerformClick();
                frm_income.rtxt_voucherNO.Text = voucherNo;
                frm_income.btn_query.PerformClick();

            }
        }
