Hi all

 I'm trying to recreate one of the examples from the Developing Enhanced Web Experiences with Microsoft? ASP.NET AJAX Extensions clinic.

 I have the following javascript code in my page:

<script language="javascript" type="text/javascript">
	<!--
		var helpButton;
		var helpDiv;
		
		var hoverBehavior;
		var popupBehavior;
		var chooseANumber;
		var toolTipDiv;
		
		function pageLoad (sender, e)
		{
			// rollover and popup behaviour
			toolTipDiv = $get('tooltipDiv');
			chooseANumber = $get('chooseANumber');
			
			popupBehavior = $create(Sys.Preview.UI.PopupBehavior, 
				{'parentElement':$get('chooseANumber'),
				'positioningMode':Sys.Preview.UI.PositioningMode.BottomLeft},
				null, null, toolTipDiv);
			
			hoverBehavior = $create(Sys.Preview.UI.HoverBehavior,
				null,
				{'hover':onHover, 'unHover':onUnhover},
				null, chooseANumber);
			
			// Click behaviour
			helpDiv = $create(Sys.Preview.UI.Label, null, null, null, $get('helpDiv'));
			helpDiv.set_visibilityMode(Sys.UI.VisibilityMode.collapse);
			helpButton = $create(Sys.Preview.UI.Button, null, {'click':onClick},
				null, $get('helpButton'));
		}
		
		function onClick()
		{
			if (helpDiv.get_visible())
			{
				helpDiv.set_visible(false);
			}
			else
			{
				helpDiv.set_visible(true);
			}
		}
		
		function onHover()
		{
			popupBehaviour.show();
		}
		
		function onUnhover()
		{
			popupBehaviour.hide();
		}
	//-->
    </script> 

I get an error on the popupBehavior = $create(Sys.Preview.UI.PopupBehavior ... line:

Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: type

Can anyone help with this, please?

Thanks as always

Hi,

This error 'usually' occurs if your web.config is not updated with ajax configuration settings.

To make your site ajax enabled, you have to make some changes in the web.config. Hope you have done that.

HTH.

Hi all

Thanks for the responses. I created the project as a new ASP AJAX Futures Web Application Project so that should have added everything necessary to the web.config. I did go to the site referenced and changed my web.config as follows just in case:

Still gives me the same JavaScript error though.

Thanks as always

Anyone able to assist with this please?

 Hi Shivonne,

I don't have this version on my machine yet. But my suggestions for you is to debug your script to find out the actual cause.

Please refer to this documentation for more information: http://msdn2.microsoft.com/en-us/library/k2h50zzs(VS.80).aspx
 

Thanks Raymond. I'll check that out and see what I can find. 

It fails in the $create function on line 15:

1    var $create = Sys.Component.create = function Sys$Component$create(type, properties, events, references, element) {
2        /// <param name="type" type="Type"></param>
3        /// <param name="properties" optional="true" mayBeNull="true"></param>
4        /// <param name="events" optional="true" mayBeNull="true"></param>
5        /// <param name="references" optional="true" mayBeNull="true"></param>
6        /// <param name="element" domElement="true" optional="true" mayBeNull="true"></param>
7        /// <returns type="Sys.UI.Component"></returns>
8        var e = Function._validateParams(arguments, [
9            {name: "type", type: Type},
10           {name: "properties", mayBeNull: true, optional: true},
11           {name: "events", mayBeNull: true, optional: true},
12           {name: "references", mayBeNull: true, optional: true},
13           {name: "element", mayBeNull: true, domElement: true, optional: true}
14       ]);
15       if (e) throw e;

 It looks like it doesn't recognise the Sys.Preview.UI.Data.PopupBehavior value I am passing in.

I have the following ScriptManager in my code:

<asp:ScriptManager ID="ScriptManager1" runat="server" enablepagemethods="true" enablepartialrendering="true" scriptmode="Debug">
   <Scripts>
      <asp:ScriptReference Assembly="Microsoft.Web.Preview" Name="PreviewScript.js" />
   </Scripts>
</asp:ScriptManager>

 Is there anything else I should have configured in the ScriptManager besides this? 

I'm receiving the same JavaScript error. I've gone through the same steps as above, I installed the ASP.NET Futures (July 2007) release, and created a new ASP.NET AJAX Futures Web Application via Visual Studio New Projects templates. I've successfully got other components working such as the TimerControl (part of ASP.NET Futures) on the same ASP.NET page. Searching on Google for "Sys.Preview.UI.PopupBehavior" I see other people with the same with issue, unresolved.

I assume it is reference missing, but I cannot find any docs that list requirements to use this object. Has anyone resolved this problem?
