    <p>I am beginning to make friends with SubSonic 3.0.0.3 - SimpleRepository. Since you/I have to create every object class, so I made a simple code below, just to save some time.</p> <p>My only question is, does my mapping are correct (DB DataType to .Net DataType)?</p> <p><strong>Here's the simple code:</strong></p> <pre><code>public string CreateClassEntity(string ConnectionSring, string TableName) { SqlDatabase db = new SqlDatabase(ConnectionSring); string sqlCommand = "SELECT TOP 1 * FROM " + TableName + ""; DbCommand dbCommand = db.GetSqlStringCommand(sqlCommand); DataSet subsonicDataSet = db.ExecuteDataSet(dbCommand); DataTable subsonicDataTable = subsonicDataSet.Tables[0].Clone(); string classEntity = "public class " + TableName + " \n{"; foreach(DataColumn column in subsonicDataTable.Columns) { classEntity += "\n\tpublic "; classEntity += column.DataType.ToString().Replace("System.", string.Empty) + " "; classEntity += column.ColumnName + " "; classEntity += "{ get; set; }"; } classEntity += "\n}"; return classEntity; } </code></pre> <p><strong>Sample target Table (SQL 2008):</strong></p> <pre><code>CREATE TABLE [kiss].[Users]( [ID] [int] IDENTITY(1,1) NOT NULL, [UserName] [nvarchar](20) NOT NULL, [UserPassword] [varbinary](128) NULL, [UserTypeID] [tinyint] NOT NULL, [ByPassAccessRestrictionsFlag] [bit] NOT NULL, [IsEnforcePasswordPolicy] [bit] NOT NULL, [PasswordExpirationDate] [datetime] NULL, [IsPwdChangeNextLogin] [bit] NOT NULL, [ShowLatestNewsFlag] [bit] NOT NULL, [SortRowNumber] [int] NOT NULL, [CreatedDate] [datetime] NOT NULL, [CreatedBy] [nvarchar](20) NOT NULL, [UpdatedDate] [datetime] NOT NULL, [UpdatedBy] [nvarchar](20) NOT NULL, [DeletedDate] [int] NULL, [EntityTypeID] [int] NOT NULL ) </code></pre> <p><strong>Sample Class Output:</strong></p> <pre><code>public class Users { public Int32 ID { get; set; } public String UserName { get; set; } public Byte[] UserPassword { get; set; } public Byte UserTypeID { get; set; } public Boolean ByPassAccessRestrictionsFlag { get; set; } public Boolean IsEnforcePasswordPolicy { get; set; } public DateTime PasswordExpirationDate { get; set; } public Boolean IsPwdChangeNextLogin { get; set; } public Boolean ShowLatestNewsFlag { get; set; } public Int32 SortRowNumber { get; set; } public DateTime CreatedDate { get; set; } public String CreatedBy { get; set; } public DateTime UpdatedDate { get; set; } public String UpdatedBy { get; set; } public Int32 DeletedDate { get; set; } public Int32 EntityTypeID { get; set; } } </code></pre>

    1. COIt looks like you're trying to replicate the code generation provided by the linq template. I don't understand why you're doing this?

    2. COFirst of all, I got no idea, that is existing in linq template, since I never have a success running it and same as with ActiveRecords (dragging those .TT files) =(. That is why I end up in SimpleRepository and force creating a class object by hand. If you can help me run Linq Templates & ActiveRecords that would be cool.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
