If I understand you right, EF generates something like <blockquote> <pre><code>class YourStudent { public int studentId { get; set; } public string name { get; set; } public string lastName { get; set; } public virtual ICollection<Course> Courses { get; set; } } </code></pre> </blockquote> and there is <pre><code>class TheirStudent { public int studentId {get;set;} public string name { get; set; } public string lastName { get; set; } } </code></pre> and you want to stuff values from a TheirStudent instance into a YourStudent instance. Maybe something like <pre><code>YourStudent s1; TheirStudent s2; Type t = typeof(YourStudent); Type t2 = typeof(TheirStudent); foreach (PropertyInfo pinfo in t.GetProperties()) { if (pinfo.GetGetMethod().IsVirtual && pinfo.PropertyType.IsGenericType && pinfo.PropertyType.GetGenericTypeDefinition() == typeof(ICollection<>)) { // This is [probably] a nav property. Courses would be in here } else if (pinfo.GetGetMethod().IsVirtual) { // if you have 0..1 or 1..1 nav properties you might muck around in here } else if (!pinfo.GetGetMethod().IsVirtual) { // This is [probably] a column - studentId, name, etc would be here // you could pull values over like so: PropertyInfo pinfo2 = (from ps in t2.GetProperties() where ps.Name == pinfo.Name select ps).SingleOrDefault(); if (pinfo2 != null) { object value = pinfo2.GetValue(s2, new object[] { }); pinfo.SetValue(s1, value, new object[] { }); } } } </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.
