[asp.net] Select current date by default in ASP.Net Calendar control

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

<asp:Calendar ID="Calendar1" runat="server"  SelectedDate="" ></asp:Calendar>

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?

DateTime.Now will not work, use DateTime.Today instead.

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.

protected void Page_Load(object sender, EventArgs e)
    Calendar1.SelectedDate = DateTime.Today;
}

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.

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

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

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;
      ...
    }
 }

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.

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:-

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

Two ways of doing it.

Late binding

<asp:Calendar ID="planning" runat="server" SelectedDate="<%# DateTime.Now %>"></asp:Calendar>

Code behind way (Page_Load solution)

protected void Page_Load(object sender, EventArgs e)
{
    BindCalendar();
}

private void BindCalendar()
{
    planning.SelectedDate = DateTime.Today;
}

Altough, I strongly recommend to do it from a BindMyStuff way. Single entry point easier to debug. But since you seems to know your game, you're all set.

DateTime.Now will not work, use DateTime.Today instead.

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

dtpStartDate.SelectedDate = Convert.ToDateTime(DateTime.Now.Date);
dtpStartDate.VisibleDate = Convert.ToDateTime(DateTime.Now.ToString());
