将行添加到表单 [英] Add row to a form

问题描述

我正在创建一个订单表格，其中有两个下拉框，这些下拉框将从数据库中填充以供选择，还有一些文本框需要填写(所有框均水平排列) .我希望能够点击添加" 行"按钮并复制所有下拉菜单和文本框，以再次填写，并在订单中添加另一行.我有以下代码，但在弄清楚如何使其能够执行所需功能时遇到了一些麻烦.

I am in the process of creating an order form where I have a couple of drop-down boxes that will be populated from a database to select from and text boxes that need to be filled in (all horizontally alighned). I would like to be able to click an "add row" button and duplicate all of the drop-downs and text boxes to be filled in again and add another line to the order. I have the following code, but I am having a little trouble figuring out how I would make it do what I need.

        protected void addNewRow()
        {
            // Get Row Count
            int currentRowCount = 3;

            // Add 1 to row count
            string newRowCount = Convert.ToString(currentRowCount++);

            lblErrorMessage.Visible = true;
            lblErrorMessage.Text = "Row Count: " + newRowCount;

            try
            {
                // Add button
                //Button btnSave = new Button();
                //pnlTest.Controls.Add(btn);

                TextBox txtDescription = new TextBox();
                txtDescription.ID = "txtDescription" + newRowCount;
                pnlTest.Controls.Add(txtDescription);
            }
            catch (Exception ee)
            {
                // Add row error
                lblErrorMessage.Text = ee.Message.ToString();
            }
        }
