Question

我正在创建一个项目，我正在创建一个动态表。现在根据我的情况，我将链接按钮添加到表格单元格，但我的链接按钮的点击事件不起作用。我不明白为什么它不是工作，既不显示任何错误。以下是我的代码

public void makeCalendar()
{
    tblcalendar.Rows.Clear();
    //for current month
    DateTime startingdate = StartDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    DateTime enddate = EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    string startingday = startingdate.DayOfWeek.ToString();
    int startingdayno = Convert.ToInt32(startingdate.DayOfWeek);
    string endday = enddate.DayOfWeek.ToString();//like saturday is 6,stating is from monday with 1 and ending is sunday with 7
    int enddayno = Convert.ToInt32(enddate.DayOfWeek);
    //for prevoius month
    DateTime enddateprevious = (EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno)));
    //for next month
    DateTime startingdatenext = StartDateOfMonth(DateTime.Now.AddMonths(1));
    DateTime dtstart=startingdate.AddDays(-(startingdayno+1));
    //sMonthName = "January";
    //int iMonthNo = Convert.ToDateTime("01-" + sMonthName + "-2011").Month; 
    for (int i = 0; i <7;i++)
    {
        TableRow tr = new TableRow();
        for (int j = 0; j < 7;j++ )

听起来你正在添加一个按钮，但没有将事件监听器绑定到它。我不太了解asp.net如何进行事件绑定，但听起来这可能是你的问题。

也许这个链接有帮助？
