Telerik“Live Demos”解决方案 - 连接字符串和数据库设置

Question

寻找一个人谁设置的Telerik Rad Controls for ASP.NET AJAX Live Demos项目之前......我最近下载了Telerik Rad Controls for ASP.NET AJAX框架。我正在使用Telerik Rad Controls for ASP.NET（非AJAX）框架将我们公司的一些代码从大约5-6年前升级到新的AJAX框架。许多旧控件在最新的浏览器版本（Google Chrome 12，Mozilla Firefox，Internet Explorer）中无法使用。有些控件在某些浏览器中可用，但在其他浏览器中不起作用，有时并不总是与浏览器打开的浏览器相同。

我尽最大努力解决了我们公司框架中存在的问题，但我们仍然存在一些问题，以前我发布过的问题都是如此。这些正是我想要解决的问题。于是我开始安装演示项目。

我们公司还没有使用Visual Studio 2010，所以昨天我将Telerik Live Demos项目降级到Visual Studio 2008.我手动转换* .sln文件进行了3次更改。幸运的是，没有.csproj/ .vbproj文件（很明显，因为它们在他们的网站项目中都有这两种语言）。然后，我将.NET版本从4.0更改为3.5，对网站bin文件夹进行了必要的Bin35更新，删除了项目中的4个不同的.NET 4.0 dll，并使用这些程序集卸载了任何文件，在IIS 7中进行了必要的更改，编译的解决方案，一切都很好....

直到我试图查看一些控件。然后我发现他们有2个需要下载的数据库（Northwind & Telerik）（10.mdf/.ldf文件）和Attach to SQL Server 2008.我今天做了这个，更新了连接字符串，但是我仍然有一个问题。我希望这是我需要解决的许多问题中的最后一个，以使其正常工作，以便我可以理解该框架。

仅供参考：我现在使用web.config.35文件作为我的“web.config”文件。我还将解决方案/项目的.NET版本从2.0更改为3.5。这个可以吗？我认为这是因为2.0 dll仍然可以在3.5网站上正常运行，因为它仍然是2.0体系结构。

有人可以向我解释所有这些连接字符串的用途和必要的设置？我有连接到SQL Server的* .mdf和* .ldf文件，但它们仍处于集成模式（用于访问）。我也重新命名了数据库...在附加和添加* .mdf文件后，数据库名称真的很长！

web.config中的连接字符串：

<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="NorthwindConnectionString35" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Northwind.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> 
     <add name="TelerikConnectionString35" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Telerik.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> 
     <add name="NorthwindEntities" connectionString="metadata=res://*;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Northwind.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> 
     <add name="TelerikEntities" connectionString="metadata=res://*;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Telerik.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> 
     <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> 

在现场演示观看ComboBox控件时（运行现场演示网站时）仍收到此错误：

假设您拥有允许您的APP将.mdf文件附加到SQL Server的管理员凭据，请设置User Instance = false（编辑：在哟中将其更改为false你的连接字符串）。

我会认为这就是为什么你目前得到上面的错误。不是说这会完全解决你所有的问题，但它应该帮助你解决这个错误。
