System.Web.UI.ScriptManager not recognized

Hi All,

First of all I am new to using Ajax controls, and am having a bit of trouble trying to add them to an exsisting ASP.NET application.

I am using:

Windows Vista Business

IIS7

VS 2005 SP1

AJAX 1.0

When trying to add an Ajax script manager to a page i get an error in the designer.vb file saying that the System.web.ui.scriptmanager type is not recognized. Also when I try to run the app I get the "sys is not found" javascript error which I would expect is related to my issue.

I have searched the fourms etc for quite a while and have found one other post regarding this, although it didn't seem to solve my problem.

I have tried running a Ajax enabled project and tested it in both the VS and IIS webservers which works well. I have also copied a web.config file from an Ajax enabled site so I dont think it is the web.config file.

Could anyone shed some light on this?

Thanks in advance.

First of all When u create "AJAX Enabled Site", You don't have to manually include

ScriptManager Control. It will be automatically placed on the form.

Why do you want to place ScriptManager manually ?

You can use directly AJAX Enabled Web Site..

Hi Chetan,

I am adding Ajax controls to a "Standard" ASP.NET application and not a Ajax enabled app, when adding the control which i want to use (ModalPopup) it says that it requires an instance of the ScriptManager Control on the page which makes sense as to my understanding any page that uses Ajax controls needs a ScriptManager control or a ScriptManager Proxy.

The reason I mentioned the Ajax Enabled site is that I guess it illustrates the fact that its not a problem with the instalation of Ajax but rather an issue specifically with the app i am working with.

Can you think of anything that I might have missed that would cause this to happen?

Thanks again for your help.

Regards,

Glen

Tab Container/Panel with Master Page

I have a VB.Net/Asp.Net 2005 application and I would like to use a Master Page with a tab control

Inside the master page I have a tab control with five Tab Panels and I would like to put a ContentPlaceholder inside each tab's ContentTemplate but I am not allowed to do that. Does anyone have any good samples using Tab Containers/Panels inside a master page like this?

thanks

Hi,

As you've discovered, it can't be used this way unless you change the access modifier of TabPanelContainer to public and rebuild it.

Tab Control Problem

Hi

I m using Ajax Tab Control in my application it is working fine but with one problem. I have three tab pages on the tab control. Every tab page has a data grid and that cause the page to post back. The problem is when I do some post back on tab and then move to another tab and cause the page to post back the tab control select the previous tab on the current on which I am working.

Is there something that I m missing ??

hi

But the solution over there is not working for me. Any other idea/workaround??

Did you try the solution by Howeird? That worked for me.

Use updatepanels around your grids.. That should prevent full postbacks.. If I understood your problem right, that should solve it..

tab panel header text not changing programaticlly??

Hi All, I am using AJAX tabcontainer in my one of the web application. This application needs to be support english as well as japanese language. I had tried to change tabpanel1 text at run time by resource file(.resx file) and using Tabcontainer.Tabs[0].HeaderText property. But still tabpanel1 is coming on webpage. If i make the changes at design time, it is working fine. Please let me know if anyone has idea over same. Thanks In Advance Arnold

Can you post your code?

Hi,Pls find code for changing the tabpanel text at run time: TabContainer1.Tabs[0].HeaderText = Resources.Resource.tabpanel1; TabContainer1.Tabs[1].HeaderText = Resources.Resource.tabpanel2;Please let me know what I am doing wrong?Thanks Arnold.
Any idea?

In which event do you use the code you provided?

In page_load function.

Are you creating any of the objects dinamically?

No, I have created same at design time.Thanks & Regards,Arnold

Oh, yes. One more question... What version of Visual Studio are you using?

What version of the toolkit are you using?

Try just setting your header to a fixed string to eliminate the complexity, e.g. TabConainer.Tabs[0].HeaderText = "Testing" or TabPanel1.HeaderText = "Testing";

You also should be able to do something like HeaderText="<%$Resources:myResources, Welcome %>" in the ASPX. Seehttp://www.codeproject.com/useritems/localization.asp for more information.

Hi Guys,

I am using ASP.NET 2.0 AJAX Extensions toolkit and I had already tried both ways few days back, but this was not working, that's why I have droped a forum here :-)

Please let me know whether this is a bug, or how can i fix this?

Thanks & Regards,

Arnold.

When you set a static string (e.g. TabContainer.Tabs[0].HeaderText = "Testing" or TabPanel1.HeaderText = "Testing";), do you still have the issue?

Assuming you do, it sounds to me like something in your code is overwriting your dynamic assignment. This is not a bug with the Toolkit as I have done this with version 10920.

By the way, you are confusing two different technologies... "ASP.NET 2.0 AJAX Extensions toolkit" isn't a version of the Toolkit. TheASP.NET AJAX 1.0 Extensions provide you with the UpdatePanel, ScriptManager, etc. while theAJAX Control Toolkit gives you all the extra controls like the Tabs, Accodion, etc. When I asked what version of the Toolkit you were using I was refering to the build number.

I suggest you try the 10920 build and see if you still are having the issue:http://www.codeplex.com/AtlasControlToolkit/Release/ProjectReleases.aspx?ReleaseId=4941. If you are, all signs point to a bug in your code. In that case, step through your program putting a watch on the TabPanel1.HeaderText seeing where it ends up being changed.

Hi,I apologize for giving wrong information. Actually I am using ASP.NET 2.0 AJAX Extension and AJAX toolkit version 1.0.10920.0 both.And even I had tried in all the ways:TabContainer1.Tabs[0].HeaderText = "sample app";TabContainer1.Tabs[0].HeaderText = Resources.Resource.tabpanel1;in aspx file,">But nothing is working.In watch window, right value is displaying but on GUI, value is same as the design time value.Any efforts regarding same will be appreciated as this minor issue is taking so much of time.Thanks & Regards,Arnold

Ok, with 10920, I know for a fact it works. There is a problem somewhere in your code, something must be overwriting your tab's header. Do a search for "HeaderText" in your app to see if in fact it is being set somewhere else.

Hi Damien,Thanks for reply. Issue has been solved finally.Issue was with headertemplate. headertemplate in aspx. was overwriting the information.Thanks & Regards,Arnold
