[ASP.NET] The Calender Control

November 9, 2004

Hey, just learning ASP.NET with VB.NET/VS.NET atm (im following a Wrox book)... got a calender web control on my page but it doesn't seem to change the month when I hit >> or << at the top of the calender. Simple problem probably but grrrrr... :angry:

Here's my code:

&lt;%@ Page Language="vb" AutoEventWireup="false" Codebehind="News.aspx.vb" Inherits="FriendsReunionUI.News"%>;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"&gt;
&lt;HTML&gt;
	&lt;HEAD&gt;
  &lt;title&gt;News&lt;/title&gt;
  &lt;meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1"&gt;
  &lt;meta name="CODE_LANGUAGE" content="Visual Basic .NET 7.1"&gt;
  &lt;meta name="vs_defaultClientScript" content="JavaScript"&gt;
  &lt;meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">t;/HEAD&gt;

	&lt;body ms_positioning="FlowLayout"&gt;
  Calender Control Test...
  &lt;form id="Form1" method="post" runat="server"&gt;
 	 &lt;P&gt;&lt;asp:Calendar id="calDates" runat="server"&gt;&lt;/asp:Calendar&gt;&lt;/P&gt;
 	 &lt;P&gt;&lt;asp:Label id="Label1" runat="server"&gt;Date Selected: &lt;/asp:Label&gt;
    &lt;asp:DropDownList id="cbDay" runat="server" AutoPostBack="True"&gt;
   	 &lt;asp:ListItem Value="0" Selected="True"&gt;Today&lt;/asp:ListItem&gt;
   	 &lt;asp:ListItem Value="1"&gt;Tomorrow&lt;/asp:ListItem&gt;
   	 &lt;asp:ListItem Value="-1"&gt;Yesterday&lt;/asp:ListItem&gt;
    &lt;/asp:DropDownList&gt;
 	 &lt;/P&gt;
  &lt;/form&gt;
	&lt;/body&gt;
&lt;/HTML&gt;

Not that long eh :p Any help is appreciated :)

BTW: 1) Do I really need all that META stuff in the <HEAD> part? 2) What does AutoEventWireup="false" do? 3) What does Inherits="FriendsReunionUI.News" actually inherit? Cheers :yes:

I assume you're doing this in .NET 1.1.

First, I'll answer your bottom two questions:

When you have an ASPX file, you have to files. FileName.aspx and FileName.aspx.vb (or FileName.aspx.cs if you're using C#). One is the markup file, and the other is the code-behind file.

When you click a button on your markup file, it has to call a method in the code-behind file. It does this by "wiring" up the events of the markup file to the code-behind file. AutoPageEventWireup will automatically wireup page events (such as Page_Load) in the code-behind file. Inherits just means the code-behind file.

It's hard to explain.

Anyway, do you have Javascript enabled? You'll need it to change dates on the Calendar control.

Yeah my calendar control moves between months when I press the next and previous buttons. Don't forget yo must wire up the Calendar1_SelectionChanged method when you want to select a date. Otherwise you won't be able to get the date the user selects

Oh yep gotcha - nah makes perfect sense to me :) Hmm, as for the Calendar control month thing still no changing - very bizarre cause yep JS is enabled. I'll try doing it again... :unsure:

Yup, about to wireup the Calendar1_SelectionChanged() method in the next step of the book, lol.

The code above works find for me. The month change when you click on the < or >.

By any change did you install the SP for .NET 1.1? You might want to take a look at this

Hmm very strange... I figured out what the problem is but not sure why it's happening?!

- I can go http://mywebsite/.../News.aspx and my page opens fine from another PC on the internet

- I can go http://mycomputername/.../News.aspx from any computer on my network (including this one which I host IIS on) and it works fine

- But if I go http://localhost/.../News.aspx it doesn't work! And the month won't change when I click << or >>

Any particular reason for this? :( I'm using IIS 5.1 that comes with WinXP Pro.

I'm normaly using a win2003 server, but for a while I ran dev server on xp and suddenly I encounted the same problem, I found no way to get localhost to work, so I just just the machine name.
