JavaScript and ASP.NET Calendar

[Blazej]

Struggling with an ASP.NET Calendar which closes when I press the "previous/next month".

I will allow it to be closed, but closed only when a select date.

<script type="text/javascript"> 
var timeout = 300; 
was close hours = 0; 
var dropdown = 0; 

mopen function (id) 
{
mcancelclosetime (); 
if (drop down) dropdown.style.visibility = 'hidden'; 
dropdown = document.getElementById (id); 
dropdown.style.visibility = 'visible'; 
}

function mclose () 
{
if (drop down) dropdown.style.visibility = 'hidden'; 
}

function mclosetime () 
{
close hours = window.setTimeout (mclose, timeout); 
} 

function mcancelclosetime () 
{
if (close hours) 
{
window.clearTimeout (close hours); 
close hours = null; 
}
} 
document.onclick = mclose; 
</script>

<div id="drop"> 
<p href="#" onmouseover="mopen('1')" onmouseout="mclosetime()"> Choose date </p> 
<div id="1" onmouseover="mcancelclosetime()" onmouseout="mclosetime()"> 
<asp:Calendar ID="Calendar1" runat="server" BackColor="Red"> </asp:Calendar> 
</div> 
</div>

I do not think the JavaScript is able to distinguish between the different places to click on the calendar, so when I had a similar case, I chose to add the calendar in an update panel to run postbacks by click on the day and the changing of the month. That way I could control the visibility, the text field value, etc backend.

You did that in AJAX?

Yes, Update Panel is an AJAX component. When you are using ASP.net 3.5 flows of these components together with the very common, and the use of the go a breeze

Have read some about such partial-page-postbacks using updatepanels genes is a whole bunch of data at every post back, so that the load on the server eventually can become great. That is why I mentioned this to use: we should be careful to use updatepanels sections of the website where there is heavy traffic. This is not the case for management systems, or other type of web applications where only a select group has access to the website.

Have tried to insert AJAX components, first, because I thought this is the easiest way, but will typically Prefix error message:

"This control can not be displayed because its TagPrefix is not registered in this Web Form."

So I registered:

<%@ Register Assembly = "AjaxControlToolkit" Namespace = "AjaxControlToolkit" TagPrefix = "id"%>

but it will still not use the controller.
