如何使用特定方案将行添加到表 [英] how to add row to table with specific scheme

问题描述

我有一个包含此div的asp页，此表默认包含两行:

Hi, i have an asp page that contains this div, this table by default contains two rows:

<div>
        <table border="1"  runat="server" id="tblInfo">
            <tr>
                <td>Row 1</td>
            </tr>
            <tr>
                <td>Row 2</td>
            </tr>
        </table>
        <asp:Button runat="server" ID="btnAdd" OnClick="AddNewBtnClick" Text="Add Row"/>
    </div>

这是此页后面的代码:

and this is the code behind of this page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;


namespace OTED
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        public static int counter = 0;
        protected void Page_Load(object sender, EventArgs e)
        {
            rebuildMyTable();
        }

        protected void rebuildMyTable()
        {
            if (this.ViewState["TableRowCount"] == null)
                this.ViewState["TableRowCount"] = 0;
            for (int i = 0; i < Int32.Parse(this.ViewState["TableRowCount"].ToString()); i++)
                AddNewRow();
        }
        protected void AddNewBtnClick(object sender, EventArgs e)
        {
            AddNewRow();
            if (this.ViewState["TableRowCount"] == null)
                this.ViewState["TableRowCount"] = 1;
            else
            {
                this.ViewState["TableRowCount"] = Int32.Parse((this.ViewState["TableRowCount"].ToString())) + 1;
            }
        }
        protected void AddNewRow()
        {
            HtmlTableCell cell = new HtmlTableCell();
            HtmlTableRow row = new HtmlTableRow();
            TextBox txt = new TextBox();
            txt.ID = counter.ToString();
            cell.Controls.Add(txt);
            row.Controls.Add(cell);
            int abc = tblInfo.Rows.Count;
            tblInfo.Controls.AddAt(abc, row);
            counter = counter + 1;
        }

    }
}

最后，我想这样做，当用户单击"btnAdd"时，将每次单击添加一行到表中，但是此代码无法正常工作，请问每个人都可以帮助我吗?

推荐答案

更改

int abc = tblInfo.Rows.Count;
            tblInfo.Controls.AddAt(abc, row);

致

To

tblInfo.Rows.Add(row);

您需要添加行，因为控件已经添加到行中，因此无需将控件添加到表中.

You need to add the row, because the controls are already added to the row so no need to add controls to the table.
