I need to upgrade my web solution ASP.NET 3.5 to 4.0 currently used VS 2010. Earlier upgraded from VS2008 ASP.NET 2.0 to 3.5.So project currently used in VS 2010 with ASP.NET 3.5.
Visual Studio Conversation Wizard does not pop up, when I am chancing the version number in the solution file from 11 to 10 the wizzard pop up, but it doesn't do the upgrade to 4.0.
I have a webform that has a formview (fvwContract) and inside itemtemplate there is a Tabcontainer with three tabs (invoice (spanish: factura), receipt (spanish: recibo) and beneficiary (spanish: beneficiario). I have another formview inside invoice tab (fvwFactura) with many textboxes that I need to manipulate in code behind. The thing is that I canīt reference any of them like the following:
protected void DropDownList1_SelectedIndexChanged2(object sender, EventArgs e)
{
AjaxControlToolkit.TabContainer container = (AjaxControlToolkit.TabContainer)fvwContract.FindControl("TabContainer1");
[Code]....
how to reference any control inside frwContract.TabContainer1.fvwFactura?
I have installed VSPro 2010 on my workstation. It comes with .NET 4 framework. How to I need to install .NET on the web server?
View 1 RepliesI have a gridview that was displaying and handling postbacks correctly, that is, until I upgraded to .net 4.0 (vs 2010) from .net 3.5. Now I am getting the classic (and in this context meaningless) "Input string was not in a correct format" error upon postback. The postback is initiated by a command button and the row command event handles everything nicely.
The trace shows internal grid postback handling and nothing else:
[FormatException: Input string was not in a correct format.]
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +9594283
System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +119
System.Convert.ToInt32(String value, IFormatProvider provider) +48
System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +1047....
From experience, I know this happens on late binding with wrong type casting on the ASPX side of things. However, nothing has changed. The code is the same, the only thing that changed is the upgrade to 4.0.
I have tried everything I (and a coleague) can think of to figure out what the issue is without luck. No error is raised on the code behind in any method. The only error raised is the Page_Error event and the error object contains the same crap you see in the yellow screen dump (above).
UPDATE: I narrowed the issue down to the RaisePostBackEvent method. I had to reflect the System.Web (for educational purposes of course :) assembly to figure out the code executing after my RowCommand logic(which is fine) breaks. This happens in the HandleEvent method. It checks for known command names (e.g. Select) and if it can't find a match, it defaults to the following:
[Code]....
Is this a bug or am I doing something wrong? The row object is NULL which is why it defaults to the cast. The cast assumes the argument to be an integer however and in my case I am passing a string as an argument?

to get that value entered and store it into the enteredValue variable (and yes, I know I have to do validation, etc). But when this runs, the value of the text in the textbox is "". I tried to put this up in the page load event, but then I get an error about declaring New.

i created a web setup project for my asp.net application. am trying to create an upgrade MSI that will only replace some few files in my initial installation (very minor upgrade). right now, am not getting it right because the whole initial set of files is been replaced. i guess i only need to change the package code, but i cant do this in VS.NET 2008.
View 6 RepliesWe currently have two web servers that are load balancing a website. Each server at the moment has its own copy of the site on their own hard drives. We have recently installed a SAN thats accessible by both servers so what I would like to do is move the website files on to the SAN for easy management of upgrades to the site. What steps should I take to ensure this works correctly with IIS7 and the web.config files and possibily machine.config files. For additional information the web.config's on each server is currently encrypted, how would I be able to achieve this with a SAN?
View 2 RepliesI have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.
I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.
Here is my linqkit query:
Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))
Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.
My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.
I need to upgrade a ASP.NET website for IE8. it works fine in IE6, but not in IE8. I don't want to run it in any backward compatibility mode. I would like to make any code changes that are required to make it fully compliant with IE8/Firefox. what is the best and/or easiest way to do that? is it just a case of going through each of the things that are broken and fixing them one by one or is there a more efficient way to fix these issues (some kind of utility??).

My company is looking to upgrade the web server from Server 2003 to 2008 (along with IIS of course). Currenty the websites are built using ASP.NET 3.5 (and a blog in PHP), is there anything that needs to be done to ensure the sites (forget the blog) still work on the new server? I'll no doubt upgrade the sites over time to use .Net 4 or MVC, but for the moment the transition needs to be almost seamless.
View 2 RepliesI upgraded a Website to use ASP.NET 4.0, from 3.5. This involved setting it up on a different server, with the same hosting company. I'm using a shared hosting plan on Windows Server 2008.
Since migrating, it gives an error message when I try to login to the site:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I'm using the same connection string as I did in the old version, which always worked. I also changed the permissions for the database to allow connections from the redeployed Website, via the host's control panel.
I have searched the web.config, and the source for the site, and I haven't been able to find a connection string that looks incorrect.
I've contacted the host about it, in case it is a configuration issue on their side.

I have a c# control class inside of a dll, then this control is embedded in a web page in an asp.net application by using the object tag. When the dll is compiled with .net 3.5 sp1 and the web application also runs in .net 3.5 sp1, the code works fine. But when the dll is compiled in .net 4.0 and the web application runs in 4.0, the control does not show up in the web page. All I see is a box with an object icon in the upper left corner.
