AJAX :: ToolScriptManager Is A Unknown After Upgrade To VS2010?

Jun 14, 2010

I just upgraded a project which was working fine using some ajax control toolkit components. When upgrading the project from VS2008 to VS2010 now I get an error stating that the 'ToolScriptManager is no a known element'...?My ajaxcontroltoolkit.dll is in the bin folder of the website (as it was before) but that doesn't seem to satisfy the VS2010...

The exact error is:

'ToolScriptManager is not a known element. This can occur if there is a compilation error in the website or the web.config file is missing.

In the build errors I have this error:

Error 17 Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. C:ProjectsmedlemsportalumbracoMembersEnrolment.aspx 10

Does anyone know what should be done to resolve this...?

Crystal Reports :: How To Prevent VS2010 From Asking To Upgrade

May 24, 2010

So I can't use Crystal Reports 2010, tried it, spend 8 hours debugging problems, then I rolled back. I refuse to use it now, what I have works, so I'm good with old crystal.

Ok, my problem now is that Visual Studio 2010 asks me if I want to migrate to CR2010 every single time I open the solution. Is there somewhere I can tell it not to ask me if I want to migrate the project? I never intend to upgrade, and I'd prefer it if other developers in my team don't accidentally click convert.

Ajax - UpdatePanel Works In VS2010 Development Server But Not IIS 6?

Feb 26, 2011

have a Visual Studio 2010 project which targets v4.0 of the .NET framework.In the project, I have a page with an ASP.NET UpdatePanel - which works perfectly within VS2010's development server.However, when deployed to an IIS 6 server, the controls in the UpdatePanel cause a full-page postback - not an async postback.The site has its own application pool.I've tried visiting the ScriptResource.axd URLs which are present in the rendered page and they all produce valid looking JavaScript files.I can't see any Javascript or other errors.

UpdatePanel AsyncTriggers Not Working After Upgrade To 4.0?

Mar 8, 2011

Recently, I upgraded my solution to 4.0 and everything seems to have upgraded smoothly but for ASP.NET AJAX.

I have an UpdatePanel like so:

<asp:UpdatePanel ID="pnlAdvSearch" UpdateMode="conditional" runat="server">
<asp:Button ID="btnHidden" Runat="server" OnClick="btnHidden_Click"
<asp:AsyncPostBackTrigger ControlID="btnHidden" EventName="Click"/>

I have a type-ahead textbox which triggers the btnHidden_Click event on Click/Enter etc. I'm calling the following method on textbox click/enter.

function getSelectionId() {
document.getElementById('<%=txtLocation.ClientID %>').value
theForm.__EVENTARGUMENT.value = "";

I can see a postback happening and the Page_Load executing. However, the server-side btnHidden_Click never gets fired. I do not want to disable event-validation at the page-level. What am I doing wrong here?

AJAX :: Bug In UpdatePanel Containing A Control That Has Javascript?

Apr 23, 2010

I cannot determine why this is happening, but I have narrowed it down to the javascript in one of the controls in an updatepanel.

ASP.NET 2.0 aspx structure:

A formview contains a large updatepanel. The updatepanel contains all the controls on the page. Only three controls are autopostback=true: two dropdowns and a checkbox.

The last three controls in the updatepanel are textboxes. Their autopostback=false. Each textbox has an anchor whose javascript launches a pop-up calendar window. The pop-up calendar selection populates the corresponding textbox. No problems there.

The bug happens whenever I fill in all three dates at once (I launch the calendar three times and select a date each time), and then I click Save. The form's save action fails because the code can no longer get to the controls in the formview. The formview.controls.count is zero.

It works if I fill in any two of the three dates *or* I fill in all three dates by typing the values into the textboxes (bypassing the pop-up calendar). I can fill them in random order, and any one or two are fine, but all three at once triggers the error.

AJAX :: Don't Update Control Within UpdatePanel?

Apr 14, 2010

This sounds weird, but I would like to NOT update a control that's within an update panel. Is this possible? basically the way facebook works, facebook controls are rendered on a "get" command. but I have controls within the same update panel that cause AJAX postbacks. When the postback's happen, I lose my facebook server-side controls. I am wondering if I can "unregister" a control from an update panel? Or do I just have to redesign that page.

AJAX :: How To Control Inside UpdatePanel Menu

May 28, 2010

I started a new project using VS2010. I have a menu control connected with an XML datasource inside UpdatePanel, Menu control works fine, problem is the styling. using a StaticHoverStyle Css works only after the page reloads, when I click a menu entry, the entry is selected but StaticHoverStyle does not reflects the menu items anymore (of course when I hover the items) Same behave with both Net versions 3.5 and 4. When I remove the UpdatePanel the StaticHoverStyle comes back to life ( post back occurs ).
