formview控件使用问题

Question

我用formview控件做一个提交的页面，默认显示的insert。
现在遇到3个问题大家看是否能帮忙下
1我编辑模板中的insert。需要把第一个textbox值让他自动获取当前日期时间
2对这些内置的控件如何编写代码，比如在formview中放一个按钮1个日历控件。需要点按钮才让日历控件下显示，如果不用formview直接就可以通过做按钮事件了，但是将按钮放在控件里面则无法
3日历控件我如何设置让他的默认日期是当前日期谢谢

例如你的TextBox的id为selecta,Calendar的id为Calendar1
则在1,3问题在FormView1的DataBound事件中解决,
    protected void FormView1_DataBound(object sender, EventArgs e)
    {
        ((TextBox)FormView1.FindControl("selecta")).Text = DateTime.Today.ToString();
        ((Calendar)FormView1.FindControl("Calendar1")).SelectedDate = DateTime.Today;
    }2的问题在Calendar的SelectionChanged事件中解决,
    protected void Calendar1_SelectionChanged(object sender, EventArgs e)
    {
        ((TextBox)FormView1.FindControl("selecta")).Text = ((Calendar)FormView1.FindControl("Calendar1")).SelectedDate.ToString();
    }
