AJAX :: Flex Desktop App With Embedded Browser Incompatible With .net ToolkitScriptManager?

Feb 4, 2010

I have a website that's developed in ASP.NET and uses the AJAX Toolkit (asp:ToolkitScriptManager) for a couple of extenders. The AJAX effects (e.g. ) work perfectly across IE 7, IE8, FF3.5, Safari, and Chrome. However, I embedded my site in a desktop Flex-AdobeAir application using the component which is able to run the entire site including javascript except where the AJAX is used.

I narrowed the source of the problem down to the difference between using asp:ToolkitScriptManager and asp:ScriptManager. Here's an example page that will display "Safari" in the embedded flex browser as the result of document.write(Sys.Browser.name):

<%@ Page Language="C#" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">[code]...

However, if you change

<asp:ScriptManager ID="TheScriptManager" runat="server"></asp:ScriptManager>

to

<asp:ToolkitScriptManager ID="TheScriptManager" runat="server"></asp:ToolkitScriptManager>

it suddenly does not display anything on the flex browser.

Embed Remote Desktop In Browser?

Jun 3, 2010

I would like to embed a Remote Desktop session within my browser. I must use remote desktop because my clients can't install any additional software on the server.

Here are some problems that I can already foresee:

1) I believe that I can embed an RDP ActiveX control, but then all I could support is IE. And even then, IE lockdown may forbid ActiveX controls.

2) I don't know anything about Apple computers, but I presume that they don't inherently run RDP?

3) I think there are ways to run RDP through a Java control. I don't have experience to know if this is a good or bad idea. I suppose that Java may even be disabled on some browsers, but don't know if this is a common case?

Drag And Drop Files FROM A Browser TO Desktop / App?

Aug 18, 2010

I've seen many articles about dragging files INTO a browser, but none about dragging files FROM the browser to a windows application or the desktop/windows-explorer.

I'm looking for a cross-browser solution but IE8 is our main browser. If I create a link in a web page and then drag that link from the page into Microsoft Word, it inserts a link. However, if that link is pointing at a PDF document, I would like it to embed the PDF doc inside the Word doc, as if I'd dragged it from Windows Explorer, into MS Word. Is that possible?

I've even tried pointing the link at an ASP page which returns "application/pdf" data but I still just get a link in my word doc so I suspect that links are the wrong way to go.

AJAX :: Are ModalPopupExtender And AsyncFileUpload.OnClientUploadComplete Incompatible?

Aug 28, 2010

A ModalPopupExtender works fine with a panel as the target control and the panel has an AsyncFileUpload control.

However as soon as AsyncFileUpload.OnClientUploadComplete is set to something (e.g. onclientuploadcomplete="alert('hello');"), the panel is not hidden on page load.

Is there any compatibility issue here?

AJAX :: ToolkitScriptManager/ScriptManager?

Jun 7, 2010

I have a form which I am using the RoundedCornersExtender, If I am using the ScriptManager control I am getting the following error-Error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.I googled it and found that one way to overcome this is to use the ToolkitScripyManager, I replaced the ScriptManager with the ToolkitScriptManager and I dont get the above error anymore. On this same form I am using an UpdatePanel control but from some reason I am not getting a partial render but always a full page render.

AJAX :: ToolkitScriptManager CombineScript Causes High CPU?

May 19, 2010

We have a website which uses a lot of AJAX, specifically update panels, modal popup extenders and a few other extenders. Let me give you a really brief overview of the application structure. We have a master page which hosts the ToolkitScriptManager object and then all the other pages in the site are children of this master page. We have specified the CombineScripts property to True and we have also specified the CombineScriptsHandlerUrl property to point to the handler that comes with the sample AJAX website. We have set the enableCompression and enableCaching properties to True in the web.config file.

We are trying to determine application performance on this site and we have found out that on each page request, the CPU utilization goes up to a 50% which is really very strange (as this is only for 1 user). When we change the CombinScripts property to false, the CPU utilization comes down to 3-4% for each request. The problem which we cannot understand is why is the server not able to cache the combined scripts and why does it try to combine the scripts on each request which is taking the utilization to a very high percentage. I have read a lot on the internet that if we use a handler for combining scripts, it will cache the combine scripts on the server and it will be served from the cache but clearly in our case it does not seem to be working.

We have also tried to use ScriptManager instead and include all the script references (using the ScriptReferenceProfiler) we could in the CompositeScript tag but that does the same thing to CPU as the CombineScripts.

AJAX :: Adding To ToolkitScriptManager Combined Scripts?

Jan 6, 2011

I need to $create Ajax Control Toolkit extenders (i.e. DropDown Extender) manually in JavaScript. To do so, the appropriate ACT scripts need to be loaded (i.e. DropDown.DropDownBehavior.js) manually since they are not declared in the page.

Prior to 3.5, I was loading these using the ScriptManager

[Code]....

My manually added DropDownBehavior.js script is loaded **before** the combined script containing all the ACT base classes resulting in a Value cannot be undefined. Parameter name: baseType

error in JavaScript. If I manually load the base types before DropDown.DropDownBehavior.js, I get Sys.InvalidOperationException:

Type Sys.Extended.UI.BehaviorBase has already been registered.

Is there some way to add these scripts either after the `_TSM_CombinedScripts_` or append to the end of it?

AJAX :: ToolkitScriptManager Fails On Updating UpdatePanel?

Oct 21, 2010

this is my first post in this forum, even though I often search for helps and clarifications over its threads. And many times they are definitely useful!!I had a <asp:ScriptManager> in may MasterPage, wich was used to manage various UpdatePanels I have either in Content pages or in MasterPage.Today I inserted a CalendarExtender, so I had to replace the ScriptManeger with the AJAX ToolkitScriptManager.

At the beginning it seemed to work fine (the calendar pop up and others controls got updated properly). Then I noticed that the nodes in various TreeView are not expanding any more. The TreeViews objects are placed inside an UpdatePanel, in order to expand each node without refreshing the whole content page. And, while a node expands, an UpdatePanel containing a GridView in the content page gets updated.Now, with the new ScriptManager they do not expand, but when clicking on a single node the GridView is updated properly.Here some pieces of code:

Controls registered as triggers.I know I can use only one script manager per page,

AJAX :: ToolKitScriptManager Breaking Dynamic Data Site?

Jun 25, 2010

I've got a dynamic data application that I would like to use several Ajax Controls on (I.E. combo box with auto complete instead of dropdown for foreign key edit fields). I'm running into problems when I try to edit tables. I replaced the regular script manager with the one defined in the AJAX tool kit on the master page (Site.master). The combobox displays, and the table gets updated when you click update/insert, BUT, when the site tries to redirect back to the list view it barfs up a funny URL that the browser can't resolve. EX: www.example.com/TABLENAME/%2fTABLENAME%2fList.aspx when it should be www.example.com/TABLENAME/List.aspx. It works fine with the standard scriptmanager, but the ToolKit's manager doesn't. I'm using Visual Web Developer 2010 express, language is VB, DynamicData application uses LINQ to SQL.

AJAX :: ToolkitScriptManager Extender Control Not Working In Nested Master Pages

Jan 6, 2010

I am using v3.0.31106.0 of the AjaxControlTookkit.dlll. I have nested master pages. The site Master page has the only ScriptManager & holds the oneColumn & twoColumn master pages. The twoColumn master page holds content pages. In the content page there is a update panel.

Before the update page I put the ToolkitScriptManager. In the update panel I put a button with a ConfirmBox Extender.

If I take the ToolkitScriptManager out this error goes away but then I get an error saying The ConfirmBox Extender is not recognized.According to all the posts I have read the last 24hours the master page should have the ScriptManager and the content page should hold the toolkitScriptManager.Here is my content page:
