Web Forms :: StyleSheetTheme Is No Longer Working
May 25, 2010
I have been maintaining a web application that is written using C# in VS2005 for about a year. Recently TFS was reorganized and my supervisor moved all the source code from one lacation to another. Since then I have not been able to get the application to display properly. It took me a while but I finally figured out that the issue is tied to the StyleSheetTheme property of the page declarative tag. When I removed it I can compile but the page doesn't render properly. When i add it almost all of the controls fail with this error: "An unhandled exception has occured. Cannot instantiate type 'WebPart' because there is no public parameterless constructor". This even happens on standard ASP.NET controls. I started to upgrade the application to VS 2008 but that has opened up all sorts of problems. I need to get this application running so I can continue to maintain the application.

I moved from VS2008 running on XP 32 bit to VS2010 running on Win7 64 bit and just noticed that I can't debug in NUnit like I used to.
On my old system, I just went to Debug|Attach to Process, chose NUnit.exe, and ran my tests from the NUnit GUI. VS2008 would stop at the breakpoints just as normal.
Now when I try this using NUnit 2.5.5.10112 on the new configuraiton it just skips over my breakpoints.

I'll use a default Theme in the web.config
<pages styleSheetTheme="deftheme">
But on a admin directory, i use a different theme. So i change the aspx file header:
theme="themeAdmin"
But right now he uses both themes. I would like to change it so in the admin directory he should use 1 theme and not the default one. How can i change that ?
of course by deleting it from the web.config and adding it to all other aspx files. But i want to use it in the web.config for the deftheme items.

I got a new computer with vs2008 and moved my app onto it for development. I can navigate pages but none of the AJAX is working. I get these IE errors "sys is undefined" and "webpartmanager" is undefined. I found lots of info on the web but none seemed to work/be applicable to my situation. My web.config file looks to be fine and I kept the application at asp.net 2.0.

My background image is not being applied when I switch over to using the local IIS server.
It's defined as:
<%@ Page Language="C#" StylesheetTheme="Common"...%>
VS Web Server: http://localhost:33174/Index.aspx = OK
Local IIS Server: http://localhost/MyApp/Index.aspx = background not showing
My Common.css class is defined as:
#masthead {
height:60px;
background-image:url(/images/bg_masthead.gif);
background-repeat:repeat-x;

I have three asp.net 2.0 websites running on the same host server and recently upgraded to 3.5. After making changes necessary in the root web.config all sites run, but I've lost the stylesheet for the primary site.
Before the upgrade I had the following in the root web.config
<pages styleSheetTheme="Red" />
I got errors on this line because the upgraded web.config had another <pages> section. I tried adding the stylesheetTheme='Red" to that section and the primary website ran and looked right, but the subs got an error that there was no StyleSheetTheme="Red".
Each site has it's own stylesheets. How can I restore the stylesheettheme to the primary site without putting it in the root webconfig? Or, is there another way to handle this?

I've tried various paths to the image.

Last week I posted this thread - I was having a problem with duplicate class attributes being added to my controls. I suspected theming but setting EnableTheming="false" did nothing fix the problem so I started troubleshooting elsewhere.I eventually found that setting Theme ="" should disable themeing still no luck. At that point I was sure theming was not the issue. To make a long (painful) story short I wasted a day beating my head against the wall....I eventually traced the problem back to theming and found that setting StylesheetTheme="" would kill that beast.
Well it looks like I got more than I bargained for because now when I submit my page I find that viewstate is broken. Yes, setting StylesheetTheme="" breaks viewstate. I can demonstrate 100% of the time that when StylesheetTheme="" viewstate does not work in my user control that is inside a repeater. It does work however with controls on the page. I have no idea why.
Here is Default.aspx with some controls removed[Code]....
Here is the user control:

I'm using VS 2008 with the AjaxControlToolkit and at design time I am dragging some regex validators on the page.
Prior to yesterday, when I did this, the design time control allowed me to click a little arrow in the upper right hand of the control and add an extender.
Well, now that ability to add an extender at design time is gone, and I don't know what happened.

I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

When user log's in with it's emaild and password, I have stored it's email id in session variable as: Session("user"). After logged in, If i leave the page kept opened OR ideal for sometime and after thatt if I select any option from user profile, the session variable get expired and send's me back to login page. I want that if I would create 2 to 3 session variable's it should remain activated for longer period. So that even if page kept ideal for longer period and then if selects any option, the session variable's should not be expired soon.

I had a web application that was binding a IDataReader to a repeater control. I converted the project from 3.5(2.0) to 4.0 and then I received the error:
An invalid data source is being used for rptData. A valid data source must implement either IListSource or IEnumerable.
So, I used a datatable instead and the binding worked. So it seems that they have removed this functionality with .NET 4.0.

I have a login page inside of a master page. On the left-hand side of the master page in side a navigation menu, there is a search box with a button that is set to be the default submit button via code when text has been entered into the search text box.
[Code]....
ABOVE the search box is a ASP:LoginStatus control that when the user clicks "Login" it takes you to a login.aspx page which contains a ASP:Login control inside the same master page. Without setting the LoginImageUrl and LogoutImageUrl properties of the ASP:LoginStatus, the login/logout appears as text. And the enter button works when a user enters text into the search box (submits info to search service and takes user to search results) OR if the user enters their user name and password into the Login control and hits enter (logs in and redirects user based upon role). Everything works fine. Once I set the loginImageUrl and LogoutImageUrl properties of the ASP:LoginStatus though, the enter key no longer submits anything. It will just postback the page.
I'm guessing that adding an image to those properties cause the loginstatus to take the default behavior of a button. How do I prevent it from breaking the behavior of the enter key on everything else?

I am trying to add row in DataTable CartDT using row[], which is a string array.
DataTable CartDT = new DataTable();
public void DataTableColumn()
{
CartDT.Columns.Add("Product_Name", typeof(string));
CartDT.Columns.Add("Product_ID", typeof(string));
CartDT.Columns.Add("ItemQTY", typeof(string));
CartDT.Columns.Add("Price", typeof(string));
CartDT.Columns.Add("TotalPrice", typeof(string));
[CODE]..
Now when I execute it, it gives the error that "Input array is longer than the number of columns in this table" The array row[] has exactly 5 elements in it & also DataTable CartDT has also 5 columns. Now i am not able to find exactly where i am wrong.

I have a small obsticle. I use labels to present data from database. Some data strings from database are very long which makes the labels very long too so it looks ugly because label is pushing everything to the side of the webpage. Setting label width works only when text is less then width which i set. How can i make the label only show text no longer then labels width?

I have a page that has a formview on it. Client info, name, address, usual stuff. The formview is populated by a DataSource, that calls a SQL stored procedure for the client info. It all works great.Within the formview, I have a dropdownlist for the Staff assigned to the client (StaffId is a member of the Client record called during the Formview binding). When the formview is in Item mode, the Staff name appears in a label, when in Edit mode, the dropdownlist
is bound and populated by another DataSource that calls a stored procedure of ActiveStaff. When the assigned staff exists, the StaffId is correctly bound to the DDL SelectedValue and the current staff name appears selected in the DDL when in edit mode, as it should.

I have the following code in my Global.asax file:
[code]....
To provide neat and tidy error urls like "/Error/404/TheNameOfTheRequestedPage". This works fine from VS 2008, but once published to my local machine, I get the default error page:
Error Summary
HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or
is temporarily unavailable
I've chosen not to use system.web/customErrors because I don't have access to Server.GetLastError() from there (or at least it's never worked for me) and I want to get the http code.

I had to disable cookies for some testing in a web application. now for some reason in IE I cannot get cookies working on localhost any more. They work as expected in Safari, Firefox, and Chrome, but for some unknown reason I cannot for the life of me get cookies working on localhost. I have tried literally every setting imaginable with absolutely no luck. If I change the Url to 'localhost." it works as expected, but when I just use "localhost", without the "." period, cookies are absolutely not written. What the heck did i do? I tried upgrading to IE 9 and that didn't work. I reverted back to IE 8 and still have the same problem. I'm going absolutely mad trying to firgure out what is causing this. I tried tools, internet options, privacy, advanced, and explicit tell the browser to accept all 1st and 3rd party cookies and I'll be damned if I'm on a localhost site, the cookies are not written. This has worked perfect in the past, so it's no doubt some setting I changed but I cannot for the life of me figure out what the hell is going on. If anyone has any idea of how I can remedy this, please do let me know. I've tried every setting imaginable with absolutely no luck. I hate internet explorer but that a conversation for a different day.

I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview
gridview.DataSource = myDataTable;
gridview.Databound.
If I write the following code, teh gridview will no longer show the data
gridview.DataSource = null;
gridview.Databound.
My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.

I have uploaded the WCAT results run on windows 7, same script, to http://d1yb9lkqglrfzu.cloudfront.net/IISExpress-100VU-MachineConfig.zip ts: included XSL in zip.
1.IIS Express has slighter higher requests per second, and total transactions served than normal IIS.
2.IIS Express is executing up to 100 requests at a time, while normal IIS on windows 7 is limited to 10 as designed.
3.IIS express is using 30% higher cpu, probably because of additional requests it handles at a time.
4.But on average Express requests take much longer to complete..up to 4 times longer. see Request Execution Time performance counter and time analysis (first and last byte). Express is only able to beat IIS in total requests served because it can handle more requests at a time! Theories
1.Could the fact that IIS express is printing each request to command line window even with trace set none be slowing it down.
2.I also noticed a lot of additional modules registered in IIS express applicationhost.config that are not in IIS applicationhost.config. Could then extra debugging/tracing modules be causing the problem.
3.I notice IIS express does not have FileCache and HTTPCache modules. Could that be why?
