    <p>When running the following code it leaves out one row. When I do a files.Count it says there are 4 rows but there is no data stored for the 4th row. When I run the stored procedure from within SQL Manager it returns all 4 rows and all the data. Any help?</p> <pre><code> List&lt;File&gt; files = new List&lt;File&gt;(); SqlConnection active_connection = new SqlConnection(m_connection_string); SqlCommand cmd = new SqlCommand(); SqlDataReader dr = null; try { active_connection.Open(); cmd.Connection = active_connection; cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "dalsp_Select_Organization_Files"; SqlParameter param; param = cmd.Parameters.Add("@p_organization_guid", SqlDbType.UniqueIdentifier); param.Value = new Guid(organization_guid); param = cmd.Parameters.Add("@p_file_type", SqlDbType.NVarChar, 50); param.Value = file_type; dr = cmd.ExecuteReader(CommandBehavior.CloseConnection); if (dr.HasRows) { while (dr.Read()) { File file = new File(); file.OrganizationGuid = dr["OrganizationGuid"].ToString(); file.FileGuid = dr["FileGuid"].ToString(); file.FileLocation = dr["FileLocation"].ToString(); file.FileName = dr["FileName"].ToString(); file.FileType = (FileTypeEnum)Enum.Parse(typeof(FileTypeEnum), dr["FileType"].ToString()); file.FileExtension = dr["FileExtension"].ToString(); file.FileDescription = dr["FileDescription"].ToString(); file.ThumbnailPath = dr["ThumbnailPath"].ToString(); files.Add(file); } } dr.Close(); dr = null; active_connection.Close(); cmd = null; } catch (Exception) { throw; } finally { if (active_connection.State != ConnectionState.Closed) { active_connection.Close(); active_connection.Dispose(); } } return files; </code></pre>

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.
