ASP.NET Web Pages - Connecting to the Database

ASP.NET Web Pages - Connecting to the Database

For this sample application, I have used Visual Studio 2012 RC, ASP.Net Web Page2 Beta and .Net 4.5 framework RC.
Step 1To learn more about the basics of ASP.Net web pages, please refer to my previous blog:

Step 2Add a new page in the ASP.Net web pages demo project.

    <add name="StarterSite" connectionString="Data Source=|DataDirectory|\StarterSite.sdf" providerName="System.Data.SqlServerCe.4.0" />
    <add name="student" connectionString ="Server=(local);Database=student;Trusted_Connection=True;"
         providerName="System.Data.SqlClient" />
Step 4Add the following code to get the data from the student database.
 @{            var db = Database.Open("student"); //Open the database here
            var selectedData = db.Query("SELECT * FROM student"); //get the data from student table
            var grid = new WebGrid(source: selectedData); //set the data source to the data grid

Step 7Applying styles to the WebGrid.
Add the following style information in the head section.
            <style type="text/css">
               .grid { margin: 4px; border-collapse: collapse; width: 600px; font-family:Calibri; }
               .grid th, .grid td { border: 1px solid #C0C0C0; padding: 5px; }
               .head {  background-color:Gray;  font-weight: bold; color: black; }
               .alt { background-color: #E8E8E8; color: #000; }
Step 8Add the style information to the webgrid. 

                        tableStyle: "grid",
                        headerStyle: "head",
                        alternatingRowStyle: "alt",
