blocks|key|1543051|text|如果您已经在进行数据绑定：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1543052|<asp:Calendar+ID="Calendar1"+runat="server"++SelectedDate="<%25#+DateTime.Today+%25>"+/>|code-block|syntax|javascript|1543053|会去做的。这确实需要您在某个地方执行Page.DataBind()调用(或父控件上的数据绑定调用)。如果你不这样做，并且你绝对不想在页面上有任何代码隐藏，那么你必须创建一个包含日历控件的用户控件，并设置它的selecteddate。|1543054|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

If you are already doing databinding:

<pre><code>&lt;asp:Calendar ID="Calendar1" runat="server" SelectedDate="&lt;%# DateTime.Today %&gt;" /&gt;
</code></pre>

Will do it. This does require that somewhere you are doing a Page.DataBind() call (or a databind call on a parent control). If you are not doing that and you absolutely do not want any codebehind on the page, then you'll have to create a usercontrol that contains a calendar control and sets its selecteddate.

I was trying to make the calendar selects a date by default and highlights it for the user.
However, i tried using all the options above but i only managed to set the calendar's selected date.

<pre><code>protected void Page_Load(object sender, EventArgs e)
 Calendar1.SelectedDate = DateTime.Today;
}
</code></pre>

the previous code did NOT highlight the selection, although it set the SelectedDate to today.

However, to select and highlight the following code will work properly.

<pre><code>protected void Page_Load(object sender, EventArgs e)
{
 DateTime today = DateTime.Today;
 Calendar1.TodaysDate = today;
 Calendar1.SelectedDate = Calendar1.TodaysDate;
}
</code></pre>

blocks|key|1543201|text|我在2010年的VWD中也遇到了同样的问题，碰巧，我有两个控件。一个在后台代码中可用，另一个无法访问。我认为是控件中语句的顺序导致了这个问题。我把“runat”放在“SelectedDate”之前，这似乎解决了这个问题。当我把'runat‘放在'SelectedDate’后面的时候，它仍然有效！不幸的是，我现在不知道为什么它不起作用，也没有得到不起作用的原件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1543202|这些现在都可以工作了：|1543203|<asp:Calendar+ID="calDateFrom"+SelectedDate="08/02/2011"+SelectionMode="Day"+runat="server"></asp:Calendar>

I too had the same problem in VWD 2010 and, by chance, I had two controls. One was available in code behind and one wasn't accessible. I thought that the order of statements in the controls was causing the issue. I put 'runat' before 'SelectedDate' and that seemed to fix it. When I put 'runat' after 'SelectedDate' it still worked!
Unfortunately, I now don't know why it didn't work and haven't got the original that didn't work.

These now all work:-

<pre><code>&lt;asp:Calendar ID="calDateFrom" SelectedDate="08/02/2011" SelectionMode="Day" runat="server"&gt;&lt;/asp:Calendar&gt;
&lt;asp:Calendar runat="server" SelectionMode="Day" SelectedDate="08/15/2011 12:00:00 AM" ID="Calendar1" VisibleDate="08/03/2011 12:00:00 AM"&gt;&lt;/asp:Calendar&gt;
&lt;asp:Calendar SelectionMode="Day" SelectedDate="08/31/2011 12:00:00 AM" runat="server" ID="calDateTo"&gt;&lt;/asp:Calendar&gt;
</code></pre>

blocks|key|1543251|text|实际上，我无法在aspx中获得选定的日期。以下是在代码中设置选定日期的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1543252|protected+void+Page_Load(object+sender,+EventArgs+e)
{
+++if+(!Page.IsPostBack)
+++{
++++++DateTime+dt+=+DateTime.Now.AddDays(-1);

++++++Calendar1.SelectedDate+=+dt;
++++++Calendar1.TodaysDate+=+dt;
++++++...
++++}
+}|code-block|syntax|javascript|1543253|在上面的例子中，我需要将默认的选择日期设置为昨天。关键是设置TodayDate。否则，选定的日历日期始终为今天。|1543254|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Actually, I cannot get selected date in aspx. Here is the way to set selected date in codes:

<pre><code>protected void Page_Load(object sender, EventArgs e)
{
 if (!Page.IsPostBack)
 {
 DateTime dt = DateTime.Now.AddDays(-1);
 Calendar1.VisibleDate = dt;
 Calendar1.SelectedDate = dt;
 Calendar1.TodaysDate = dt;
 ...
 }
 }
</code></pre>

In above example, I need to set the default selected date to yesterday. The key point is to set TodayDate. Otherwise, the selected calendar date is always today.

blocks|key|1543323|text|我已经尝试了上面的代码，但不起作用，这里是解决方案设置当前日期选择在asp.net日历控件|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1543324|dtpStartDate.SelectedDate+=+Convert.ToDateTime(DateTime.Now.Date);

I have tried above with above code but not working ,Here is solution to set current date selected in asp.net calendar control

<pre><code>dtpStartDate.SelectedDate = Convert.ToDateTime(DateTime.Now.Date);
dtpStartDate.VisibleDate = Convert.ToDateTime(DateTime.Now.ToString());
</code></pre>

Let's say I have an aspx page with this calendar control:

<pre><code>&lt;asp:Calendar ID="Calendar1" runat="server" SelectedDate="" &gt;&lt;/asp:Calendar&gt;
</code></pre>

Is there anything I can put in for SelectedDate to make it use the current date by default, without having to use the code-behind?

Select current date by default in ASP.Net Calendar control

假设我有一个带有日历控件的aspx页面：<asp:Calendar ID="Calendar1" runat="server" SelectedDate="" ></asp:Calendar>有没有什么可以让SelectedDate默认使用当前日期，而不必使用代码隐藏？
