Question

我遇到的问题是动态生成的Button控件只出现在最后一行。我看过这篇文章

但它建议使用ListView，我不认为我可以在这种情况下使用。我使用Panel控件和SQL数据生成一个HTML表格，在我看来它非常具体。这是我的代码背后：

//declare a dynamic button
    Button btn_continue = new Button();
    btn_continue.Click += Btn_continue_Click;
    btn_continue.CssClass = "controlButtons";
    btn_continue.Font.Size = 20;
    btn_continue.Text = "Continue this job";

    //formatting for the rows
    int oddNumber = 1;

    foreach (DataRow row in dtGetIncompleteJobs.Rows)
    {
        //grab the date and make it shorter
        DateTime date = Convert.ToDateTime(row[3].ToString());

        pnl_jobList.Controls.Add(new LiteralControl("<tr>"));
        if (centralFunctions.OddNumberCheck(oddNumber) == true)
        {
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m lightRow'>" + row[5].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + date.ToShortDateString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[0].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[1].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[2].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m lightRow'>" + row[4].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m'>"));
            btn_continue.ID = row[5].ToString();
            pnl_jobList.Controls.Add(btn_continue);
            pnl_jobList.Controls.Add(new LiteralControl("</td>"));
            oddNumber++;
        }
        else
        {
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m darkRow'>" + row[5].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[3].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[0].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[2].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[2].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m darkRow'>" + row[4].ToString() + "</td>"));
            pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m'>"));
            btn_continue.ID = row[5].ToString();
            pnl_jobList.Controls.Add(btn_continue);
            pnl_jobList.Controls.Add(new LiteralControl("</td>"));
            oddNumber++;

        }

        pnl_jobList.Controls.Add(new LiteralControl("</tr>"));
    }

这就是它的样子： html output

是否有可能按照我正在进行的方式对每行进行Button控制？我有一种感觉，我要么缺少一些简单的东西，要么走错了路。如果我遗漏任何细节，请告诉我。谢谢您的帮助。

看起来您需要将btn_continue的创建代码移动到foreach循环

//formatting for the rows
int oddNumber = 1;

//declate the button
Button btn_continue
foreach (DataRow row in dtGetIncompleteJobs.Rows)
{
    //grab the date and make it shorter
    DateTime date = Convert.ToDateTime(row[3].ToString());

    //create the button
    btn_continue = new Button();
    btn_continue.Click += Btn_continue_Click;
    btn_continue.CssClass = "controlButtons";
    btn_continue.Font.Size = 20;
    btn_continue.Text = "Continue this job";

    pnl_jobList.Controls.Add(new LiteralControl("<tr>"));
    if (centralFunctions.OddNumberCheck(oddNumber) == true)
    {
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m lightRow'>" + row[5].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + date.ToShortDateString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[0].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[1].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m lightRow'>" + row[2].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m lightRow'>" + row[4].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m'>"));
        btn_continue.ID = row[5].ToString();
        pnl_jobList.Controls.Add(btn_continue);
        pnl_jobList.Controls.Add(new LiteralControl("</td>"));
        oddNumber++;
    }
    else
    {
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m darkRow'>" + row[5].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[3].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[0].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[2].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m darkRow'>" + row[2].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-1 col-1-m darkRow'>" + row[4].ToString() + "</td>"));
        pnl_jobList.Controls.Add(new LiteralControl("<td class='col-2 col-2-m'>"));
        btn_continue.ID = row[5].ToString();
        pnl_jobList.Controls.Add(btn_continue);
        pnl_jobList.Controls.Add(new LiteralControl("</td>"));
        oddNumber++;

    }

    pnl_jobList.Controls.Add(new LiteralControl("</tr>"));
}

动态按钮控件仅出现在最后一行
