链接按钮里面的html表格单元格asp.net

Question

您好我正在动态创建链接按钮，如下所示。问题是如何在“linktopage”的位置添加链接按钮。目前，链接按钮添加在表格下方。

for(i=0;i<100;i++)
{
LinkButton lnk = new LinkButton();
lnk.ID = "lnk" + i;
lnk.Text = "open profile";
lnk.Click += new System.EventHandler(lnk_click);
this.Page.Form.Controls.Add(lnk);

htmlstring += "<tr style='height:30px;'>" +
              "<td>" + firstname + "</td>" +
              "<td>" + surname + "</td>" +
              "<td>" + email + "</td>" +
              "<td>" + mobile + "</td>" +
              **"<td>" + linktopage + "</td>" +**
              "</tr>";
                  }

        if (!Page.IsPostBack)
            Populate();

    private void Populate()
    {
        List<MyTableData> list = new List<MyTableData>();

        for (int i = 0; i < 10; i++)
        {
            list.Add(
                new MyTableData()
                {
                    FirstName = "Firstname " + i.ToString(),

                });
        }

        gv.DataSource = list;
        gv.DataBind();
    }

    protected void lnkBtn_Command(object sender, CommandEventArgs e)
    {
        string btnNumber = e.CommandArgument.ToString();

        // more code...

        lit.Text = "Button pressed <b>" + btnNumber + "</b>";
    }
}

public class MyTableData
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string Mobile { get; set; }
    public string CmdArgument { get; set; }
}

中的

<div>
    <asp:GridView ID="gv" runat="server" AutoGenerateColumns="False" CellPadding="5">
        <Columns>
            <asp:BoundField DataField="FirstName" HeaderText="First name" />

怎么样：

用**"<td>" + linktopage + "</td>" +**替换<td><asp:Panel id="lnktoPage" /></td> 并从代码中添加lnktoPage.Controls.Add(lnk);

请注意，Panel在客户端呈现为DIV。

或者......你可以动态创建html链接：

string strID = "someID";
string strLink = @"<a id=""" + strID + @"" +
                @" onclick="" " + lnk_clickMethodName + @" "" " +
                @"href=""http://www.w3schools.com"">Visit W3Schools.com!</a>";

所以，你的最终方法看起来像是：

for (int i = 0; i < 100; i++)
{
    string strID = "lnk" + i.ToString();
    string strLink = @"<a id=""" + strID + @"" +
                    @" onclick="" " + lnk_clickMethodName + @" "" " +
                    @"href=""http://www.w3schools.com"">Visit W3Schools.com!</a>";
    StringBuilder html = new StringBuilder();

    html.Append(@"<tr style='height:30px;'>");
    html.Append(@"<td>" + firstname + "</td>");
    html.Append(@"<td>" + surname + "</td>");
    html.Append(@"<td>" + email + "</td>");
    html.Append(@"<td>" + mobile + "</td>");
    html.Append(@"<td>" + strLink + "</td>");
    html.Append(@"</tr>");
}

代替链接按钮，使用href标记;这很容易......
