Telerik“Live Demos”解决方案 - 连接字符串＆amp;数据库设置

寻找一位为ASP.NET AJAX Live Demos项目设置Telerik Rad Controls的人......我最近下载了用于ASP.NET AJAX框架的Telerik Rad Controls。我正在使用Telerik Rad Controls for ASP.NET（非AJAX）框架从大约5-6年前升级到我们公司的一些代码到新的AJAX框架。许多旧控件在最新的浏览器版本（Google Chrome 12，Mozilla Firefox，Internet Explorer）中不起作用。有些控件在某些浏览器中有效但在其他浏览器中无效，有时它并不总是与它破坏的浏览器相同。

我尽我所能来解决公司框架中存在的问题，但我们仍然存在一些问题，以前是我的问题。这些是我想要解决的问题。然后我开始安装演示项目。

我们公司尚未使用Visual Studio 2010，所以昨天我将Telerik Live Demos项目降级为Visual Studio 2008.我通过进行3次更改手动转换了* .sln文件。幸运的是，没有 .csproj / .vbproj文件（显然，因为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所有文件，在IIS 7中进行了必要的更改，编制了解决方案，一切都很顺利......

直到我尝试查看某些控件。然后我发现他们有2个数据库（Northwind＆amp; Telerik）你需要下载（ .mdf / .ldf文件）和附加到SQL Server 2008.我今天做了，更新了连接字符串，但是我还有问题。我希望这是我需要解决的许多问题中的最后一个，以使其工作，以便我能理解框架。

仅供参考：我现在正在使用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？我认为这将是因为2.0 dll仍然可以在3.5站点中运行..因为它仍然是2.0架构。

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吗？我将* .mdf和* .ldf文件附加到SQL Server，但它们仍处于集成模式（用于访问）。我还重命名了数据库...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Live Demos中查看ComboBox控件时（运行Live Demos网站时）仍然出现此错误：

答案 0 :(得分：1)

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

我认为这就是您目前收到上述错误的原因。不是说这会完全解决你的所有问题，但它可以帮助你解决这个错误。
