问题继续待解决

Question

上次提出的问题，其中还是遇到很多问题，小弟现在把问题说全，请各位帮忙，感激
问题如下：
在新增时
输入一个开始时间，一个结束时间，得到这个时间段所有的天数比如：2010-05-10~2010-11-11这个时间段的天数，然后月份显示出来，其中每一个日期还要对应每一周的星期，大致如下图描述：
，在开始日期前的天数不用显示，在结束日期后的日期不用显示，进行新增操作时，如果没有选中一个日期，则提示至少选中一个日期，然后将选中的日期插入数据库，
更新时，从数据库里读出日期信息，并如图所示，把对应日期勾选上，修改后，提交更新，更新数据库，问题大致如下了，谢谢大家帮忙，求具体实例代码，3Q

Answer 3

就相当于画时间控件，其实可以通过自己画的，选择完时间，然后画日期控件（拼HTML），input type='checkbox'

Answer 4

    protected void gdvAdd_RowCommand(object sender, GridViewCommandEventArgs e)
    {        Button btn = e.CommandSource as Button;
        DateTime Table_Date = DateTime.Parse(btn.Text);
        ViewState["Table_Date"] = Table_Date;
        dataBind(sender, e);
        Label2.Text = Table_Date.ToLongDateString();
            }
    protected void gdvAdd_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        for (int i = 1; i <= 7; i++)
        {
            string t = "Button" + i.ToString();
            Button btn = e.Row.FindControl(t) as Button;
            if (btn != null)
            {
                if (btn.Text == "")
                {
                    btn.Visible = false;
                }
            }
        }

Answer 5

Count 长度 方法 网上找   /// <summary>
       /// 比较日期相差的天数
       /// </summary>
       public enum DateInterval
       {
           Second, Minute, Hour, Day, Week, Month, Quarter, Year
       }       public sealed class DateTimeManger
       {           public static long DateDiff(DateInterval Interval, System.DateTime StartDate, System.DateTime EndDate)
           {
               long lngDateDiffValue = 0;
               System.TimeSpan TS = new System.TimeSpan(EndDate.Ticks - StartDate.Ticks);
               switch (Interval)
               {
                   case DateInterval.Second:
                       lngDateDiffValue = (long)TS.TotalSeconds;
                       break;
                   case DateInterval.Minute:
                       lngDateDiffValue = (long)TS.TotalMinutes;
                       break;
                   case DateInterval.Hour:
                       lngDateDiffValue = (long)TS.TotalHours;
                       break;
                   case DateInterval.Day:
                       lngDateDiffValue = (long)TS.Days;
                       break;
                   case DateInterval.Week:
                       lngDateDiffValue = (long)(TS.Days / 7);
                       break;
                   case DateInterval.Month:
                       lngDateDiffValue = (long)(TS.Days / 30);
                       break;
                   case DateInterval.Quarter:
                       lngDateDiffValue = (long)((TS.Days / 30) / 3);
                       break;
                   case DateInterval.Year:
                       lngDateDiffValue = (long)(TS.Days / 365);
                       break;
               }
               return (lngDateDiffValue);
           }       }

Answer 6

多选 可以用ArrayList  插入判断是否为空就好了
代码如下：protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
                      ArrayList arr =null;        if (ViewState["AttendanceDays"] != null)
        {
            arr = ViewState["AttendanceDays"] as ArrayList;
        }
        if (arr == null)
        {
            arr = new ArrayList();
        }
        Button btn = e.CommandSource as Button;
        
        if (btn != null)
        {
            string t = e.CommandArgument.ToString();
            if (arr.Contains(t))
            {
                btn.BackColor = System.Drawing.Color.Empty;
                arr.Remove(t);
            }
            else
            {
                btn.BackColor = System.Drawing.Color.Red;
                arr.Add(t);
            }
        }
        ViewState["AttendanceDays"] = arr;
    }
插入时判断就好了
 if (ViewState["AttendanceDays"] != null)
        {
            arr = ViewState["AttendanceDays"] as ArrayList;
        }
        if (arr != null)
        {
            foreach (string t in arr)
            {
            
            }
        }

asp.net的calendar是可以扩展的。随便搜一下“asp.net dayrender”！
