问题描述
我正在搞clendar，在这里我有日历投降活动。
在dayrender事件中我分配了textbox1.Text =test;但在完成dayrender活动后它是不可见的？
我的代码是
<表>
< tr>
< td>
< / td>
< td>
< asp：TextBox ID =TextBox1runat =server>< / asp：TextBox>
< / td>
< / tr>
< tr>
< td>
< / td>
< td>
< asp：Calendar ID =AttenCalendarrunat =serverBackColor =WhiteBorderColor =SteelBlue
BorderWidth =1pxFont-Names =VerdanaFont-Size = 9ptForeColor =BlackHeight =275px
Width =100％FirstDayOfWeek =SundayNextMonthText =Next> PrevMonthText =< Prev
NextPrevFormat =ShortMonthShowGridLines =falseBorderStyle =NoneCssClass =monthCalendar
OnDayRender =AttenCalendar_DayRenderSelectionMode =NoneDayNameFormat =FirstLetter
OtherMonthDayStyle-CssClass =otherMonthStyleDayStyle-CssClass =dayStyleDayHeaderStyle-CssClass =dayHeaderStyle
WeekendDayStyle-CssClass =weekendDayStyleTodayDayStyle-CssClass =todayStyle
TitleStyle-CssClass = weekendDayStyle >
<％ - < TitleStyle BorderColor =SteelBlueBorderWidth =1pxFont-Bold =TrueFont-Size =10pt
Height =40pxBackColor =White ForeColor =BlackHorizontalAlign =CenterVerticalAlign =Middle/> - ％>
< / asp：日历>
< / td>
< / tr>
< / table>
使用System;
使用System.Collections.Generic;
使用System.Linq;
使用System.Web;
使用System.Web.UI;
使用System.Web.UI.WebControls;
public partial class Default3：System.Web.UI.Page
{
protected void Page_Load（object sender，EventArgs e）
{
}
protected void AttenCalendar_DayRender（对象发送者，DayRenderEventArgs e）
{
TextBox1.Text =hi;
}
}
我可能知道这有什么问题吗？

解决方案
这可能是一个错误。在我发现当我将TextBox1从AttenCalendar控件的上方移动到下面时，然后分配并显示值。
当我使用下面的代码时
< pre lang =xml> < div >
< asp：TextBox ID = txtId runat = 服务器 > < / asp：TextBox >
< < span class =code-leadattribute> / div> otherMonthStyle DayStyle-CssClass < span class =code-keyword> = dayStyle DayHeaderStyle-CssClass = dayHeaderStyle
< div >
< asp：Calendar ID = AttenCalendar runat = 服务器 BackColor = 白色 BorderColor = SteelBlue
< span class =code-attribute> BorderWidth = 1px 字体名称 = Verdana 字体-Size = 9pt ForeColor = 黑色 < span class =code-attribute> 高度 = 275px
< span class =code-attribute> 宽度 = 100％ FirstDayOfWeek < span class =code-keyword> = 星期日 NextMonthText = 下一页> PrevMonthText = < ;上一页
NextPrevFormat = ShortMonth ShowGridLines = < span class =code-keyword> false BorderStyle = 无 CssClass = monthCalendar
< span class =code-attribute> < span class =code-attribute> OnDayRender = AttenCalendar_DayRender SelectionMode = 无 DayNameFormat = FirstLetter
< span class =code-attribute> OtherMonthDayStyle-CssClass =
WeekendDayStyle-CssClass = weekendDayStyle TodayDayStyle-CssClass = todayStyle
< span class =code-attribute> TitleStyle-CssClass = weekendDayStyle >
< / asp：Calendar >
< / div >
未分配文本框值/由DayRender事件处理程序显示。
protected void AttenCalendar_DayRender（对象发件人，DayRe nderEventArgs e）
{
txtId.Text = hi;
}
但是当我的标记如下（只是textbox1是Calender控件的下方）时，同样的事情被分配了/>
< div >
< asp：Calendar ID = AttenCalendar runat = server BackColor < span class =code-keyword> = 白色 BorderColor = SteelBlue
< span class =code-attribute> BorderWidth = 1px 字体名称 = Verdana 字体 - 大小 = 9pt ForeColor = 黑色 高度 = 275px
< span class =code-attribute> 宽度 = 100％ FirstDayOfWeek = 星期日 NextMonthText = 下一页> PrevMonthText = <上一页
NextPrevFormat = ShortMonth ShowGridLines = < span class =code-keyword> false BorderStyle = 无 CssClass = monthCalendar
< span class =code-attribute> < span class =code-attribute> OnDayRender = AttenCalendar_DayRender SelectionMode = 无 DayNameFormat = FirstLetter
< span class =code-attribute> OtherMonthDayStyle-CssClass = otherMonthStyle DayStyle-CssClass < span class =code-keyword> = dayStyle DayHeaderStyle-CssClass = dayHeaderStyle
WeekendDayStyle-CssClass = weekendDayStyle TodayDayStyle-CssClass = todayStyle
< span class =code-attribute> TitleStyle-CssClass = weekendDayStyle >
< / asp：Calendar >
< / div >
< div >
< asp：TextBox ID = txtId runat = server > < / asp：TextBox >
< / div >
它已分配并显示在我的页面上。

解决方案
It might be a bug. After little rnd i found that when I move your TextBox1 from above of the AttenCalendar control to bellow, then value is assigned and displayed.
when I use the bellow code
<div> <asp:TextBox ID="txtId" runat="server"></asp:TextBox> </div> <div> <asp:Calendar ID="AttenCalendar" runat="server" BackColor="White" BorderColor="SteelBlue" BorderWidth="1px" Font-Names="Verdana" Font-Size="9pt" ForeColor="Black" Height="275px" Width="100%" FirstDayOfWeek="Sunday" NextMonthText="Next >" PrevMonthText="< Prev" NextPrevFormat="ShortMonth" ShowGridLines="false" BorderStyle="None" CssClass="monthCalendar" OnDayRender="AttenCalendar_DayRender" SelectionMode="None" DayNameFormat="FirstLetter" OtherMonthDayStyle-CssClass="otherMonthStyle" DayStyle-CssClass="dayStyle" DayHeaderStyle-CssClass="dayHeaderStyle" WeekendDayStyle-CssClass="weekendDayStyle" TodayDayStyle-CssClass="todayStyle" TitleStyle-CssClass="weekendDayStyle"> </asp:Calendar> </div>
The textbox value is not assigned/displayed by DayRender event handler.
protected void AttenCalendar_DayRender(object sender, DayRenderEventArgs e) { txtId.Text ="hi"; }
But same thing is assigned when my markup like as follows(just textbox1 is bellow of Calender control)
<div> <asp:Calendar ID="AttenCalendar" runat="server" BackColor="White" BorderColor="SteelBlue" BorderWidth="1px" Font-Names="Verdana" Font-Size="9pt" ForeColor="Black" Height="275px" Width="100%" FirstDayOfWeek="Sunday" NextMonthText="Next >" PrevMonthText="< Prev" NextPrevFormat="ShortMonth" ShowGridLines="false" BorderStyle="None" CssClass="monthCalendar" OnDayRender="AttenCalendar_DayRender" SelectionMode="None" DayNameFormat="FirstLetter" OtherMonthDayStyle-CssClass="otherMonthStyle" DayStyle-CssClass="dayStyle" DayHeaderStyle-CssClass="dayHeaderStyle" WeekendDayStyle-CssClass="weekendDayStyle" TodayDayStyle-CssClass="todayStyle" TitleStyle-CssClass="weekendDayStyle"> </asp:Calendar> </div> <div> <asp:TextBox ID="txtId" runat="server"></asp:TextBox> </div>
It is assigned and displayed to my page.
