大家好，

我想以编程方式在Panel中添加Calendar控件.

当我按下显示"按钮时，我想在面板的这两个日期之间添加日历，例如开始日期"是"2012年8月1日"，结束日期"是"2012年9月25日"，那么此时面板中有两个日历控件. > 在这两个日历中，每个星期日的背景颜色也有一个改变的条件.

大家好，
我了解了如何在这样的面板中添加日历的逻辑，
在我的ASPX"页面中，

Hi all,
I Got logic for how to add Calendar in panel like this,
In My ASPX page looks Like,

<table>
       <tr>
           <td>
               <asp:label id="Label1" runat="server" text="Start Date:" xmlns:asp="#unknown"></asp:label>
               <asp:textbox runat="server" id="txtStart" xmlns:asp="#unknown"></asp:textbox>
               <asp:calendar id="Calendar1" runat="server" onselectionchanged="Calendar1_SelectionChanged" xmlns:asp="#unknown">
               </asp:calendar>
           </td>
           <td rowspan="3">
               <asp:panel id="pnlContaint" runat="server" height="100%" width="100%" xmlns:asp="#unknown">
               </asp:panel>
           </td>
       </tr>
       <tr>
           <td>
               <asp:label id="Label2" runat="server" text="End Date:" xmlns:asp="#unknown"></asp:label>
               <asp:textbox runat="server" id="txtEndDate" xmlns:asp="#unknown"></asp:textbox>
               <asp:calendar id="Calendar2" runat="server" onselectionchanged="Calendar2_SelectionChanged" xmlns:asp="#unknown">
               </asp:calendar>
           </td>
           <td>
           </td>
       </tr>
       <tr>
           <td>
               <asp:label id="Label3" runat="server" text="Every:" xmlns:asp="#unknown"></asp:label>
               <asp:dropdownlist id="DropDownList1" runat="server" xmlns:asp="#unknown">
                   <asp:listitem value="1">Every</asp:listitem>
                   <asp:listitem value="2">Every 2nd</asp:listitem>
                   <asp:listitem value="3">Every 3rd</asp:listitem>
               </asp:dropdownlist>
               <asp:button id="Button1" runat="server" text="Show" onclick="Button1_Click" xmlns:asp="#unknown" />
           </td>
           <td>
           </td>
       </tr>
       <tr>
           <td colspan="2">
           </td>
       </tr>
   </table>

在我的代码中，

In My Code,

protected void Calendar1_SelectionChanged(object sender, EventArgs e)
   {
       txtStart.Text = Calendar1.SelectedDate.ToShortDateString();
   }
   protected void Calendar2_SelectionChanged(object sender, EventArgs e)
   {
       txtEndDate.Text = Calendar2.SelectedDate.ToShortDateString();
   }
   protected void Button1_Click(object sender, EventArgs e)
   {

       DateTime dtTemp = new DateTime(Calendar1.SelectedDate.Year, Calendar1.SelectedDate.Month, 1);
       while (dtTemp < Calendar2.SelectedDate)
       {

           Calendar cal = new Calendar();
           cal.ShowNextPrevMonth = false;
           cal.TodaysDate = dtTemp.Date;
           cal.DayRender += new DayRenderEventHandler(cal_DayRender);
           pnlContaint.Controls.Add(cal);
           dtTemp = dtTemp.AddMonths(1);
       }
   }

   void cal_DayRender(object sender, DayRenderEventArgs e)
   {
       e.Day.IsSelectable = false;
   }
