test.aspx页面调用

html页面写入:<asp:textbox id="StockTime" runat="server" onfocus="calendar();" ReadOnly=True></asp:textbox>

即可调用梅花雨日历控件显示.其中必须加入charset="gb2312" 如果没有该句,无法调用；另外如果使用的是vs2005的话，还必须把test.aspx页面里的<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
这句去掉，否则在vs2005无法显示日历。

protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = Request.Form["StockTime"];
    }

上面这段代码可以在点击按钮后将日历控件的日期值赋给Label1控件显示出来。
