Looking for a person who’s setup the Telerik Rad Controls for ASP.NET AJAX Live Demos project before… I recently downloaded the Telerik Rad Controls for ASP.NET AJAX framework. I’m in the process of upgrading some of our company’s code using the Telerik Rad Controls for ASP.NET (non-AJAX) framework from about 5-6 years ago to the new AJAX framework. Many of the old controls don’t work in the latest browser releases (Google Chrome 12, Mozilla Firefox, Internet Explorer). Some controls work in some browsers but not others, and sometimes it’s not always the same browser where it broke.
I did the best I could to fix the existing issues from our company’s framework, but we still have some remaining issues, previously posted as questions by me. Those are what I’m trying to fix. So then I proceeded to get the demo project installed.
Our company doesn’t use Visual Studio 2010 yet, so yesterday, I downgraded the Telerik Live Demos project to Visual Studio 2008. I manually converted the *.sln file by making 3 changes. Luckily there wasn’t a .csproj/.vbproj files (obviously since they have both languages in their website project). I then changed the .NET version from 4.0 to 3.5, made the necessary Bin35 updates to the web site bin folder, removed 4 different .NET 4.0 dlls in the project and unloaded any files using those assemblies, made the necessary changes in IIS 7, compiled the solution and all was well….
Until I tried to view some of the controls. I then discovered they have 2 databases (Northwind & Telerik) you need to download (.mdf/.ldf files) and Attach to SQL Server 2008. I did that today, updated the connection strings, but I’m still having an issue. I’m hoping this is the last of many issues I need to fix to get this working so I can understand the framework.
FYI: I’m using the web.config.35 file as my “web.config” file right now. I also changed the solution/project’s .NET version from 2.0 to 3.5. Is this okay? I figured it would be since 2.0 dlls can still function okay in a 3.5 site.. since it’s still the 2.0 architecture.
Can someone explain to me what all of these connections strings are for and the necessary setup? I have the *.mdf and *.ldf files attached to SQL Server, but they are still in integrated mode (for access). I also renamed the databases… after attaching and adding the *.mdf files, the database names were REALLY LONG!
web.config connection strings:
<connectionStrings>
<add name="NorthwindConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Northwind.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
<add name="TelerikConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Telerik.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />

<add name="QSFRatingsConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|QSFRatings.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
<add name="SelfReferencingDbConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|TelerikSelfReferencingDb.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
</connectionStrings>
Still getting this error when viewing the ComboBox control in the Live Demos (when running the Live Demos website):
Server Error in '/' Application.

Assuming you have admin credentials that allow your APP to attach the .mdf files to SQL server, set User Instance = false (Edit: change this to false in your connection strings).
I would assume that is why you are currently getting that error you see above. Not saying this will completely fix all of your problems, but it should help you with that error.
-Hope that helps
