Telerik「Live Demos」解決方案 - 連接字符串和數據庫設置

Question

尋找一個人誰設置的Telerik Rad Controls for ASP.NET AJAX Live Demos項目之前......我最近下載了Telerik Rad Controls for ASP.NET AJAX框架。我正在使用Telerik Rad Controls for ASP.NET（非AJAX）框架將我們公司的一些代碼從大約5-6年前升級到新的AJAX框架。許多舊控件在最新的瀏覽器版本（Google Chrome 12，Mozilla Firefox，Internet Explorer）中無法使用。有些控件在某些瀏覽器中可用，但在其他瀏覽器中不起作用，有時並不總是與瀏覽器打開的瀏覽器相同。

我盡最大努力解決了我們公司框架中存在的問題，但我們仍然存在一些問題，以前我發佈過的問題都是如此。這些正是我想要解決的問題。於是我開始安裝演示項目。

我們公司還沒有使用Visual Studio 2010，所以昨天我將Telerik Live Demos項目降級到Visual Studio 2008.我手動轉換* .sln文件進行了3次更改。幸運的是，沒有.csproj/ .vbproj文件（很明顯，因爲它們在他們的網站項目中都有這兩種語言）。然後，我將.NET版本從4.0更改爲3.5，對網站bin文件夾進行了必要的Bin35更新，刪除了項目中的4個不同的.NET 4.0 dll，並使用這些程序集卸載了任何文件，在IIS 7中進行了必要的更改，編譯的解決方案，一切都很好....

直到我試圖查看一些控件。然後我發現他們有2個需要下載的數據庫（Northwind & Telerik）（10.mdf/.ldf文件）和Attach to SQL Server 2008.我今天做了這個，更新了連接字符串，但是我仍然有一個問題。我希望這是我需要解決的許多問題中的最後一個，以使其正常工作，以便我可以理解該框架。

僅供參考：我現在使用web.config.35文件作爲我的「web.config」文件。我還將解決方案/項目的.NET版本從2.0更改爲3.5。這個可以嗎？我認爲這是因爲2.0 dll仍然可以在3.5網站上正常運行，因爲它仍然是2.0體系結構。

有人可以向我解釋所有這些連接字符串的用途和必要的設置？我有連接到SQL Server的* .mdf和* .ldf文件，但它們仍處於集成模式（用於訪問）。我也重新命名了數據庫...在附加和添加* .mdf文件後，數據庫名稱真的很長！

web.config中的連接字符串：

<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> 

在現場演示觀看ComboBox控件時（運行現場演示網站時）仍收到此錯誤：

假設您擁有允許您的APP將.mdf文件附加到SQL Server的管理員憑據，請設置User Instance = false（編輯：在喲中將其更改爲false你的連接字符串）。

我會認爲這就是爲什麼你目前得到上面的錯誤。不是說這會完全解決你所有的問題，但它應該幫助你解決這個錯誤。

-Hope，幫助 -J
