    <p>I've got a set of classes with propperties and a main class which has lists of the set of classes.</p> <pre><code>public class MainClass { public List&lt;ClassA&gt; listA {get;set;} public List&lt;ClassB&gt; listB {get;set;} public List&lt;ClassC&gt; listC {get;set;} public object[] loop = {listA, listB, listC}; } class ClassA { public Guid id {get;set;} public string text {get;set;} public int number {get;set} public status {get;set;} public object[] loop = {id, text, number}; } class ClassB { public Guid id {get;set;} public string text {get;set;} public Image pic {get;set} public status {get;set;} public object[] loop = {id, text, pic}; } class ClassC { public Guid id {get;set;} public byte[] data {get;set;} public DateTime date {get;set;} public status {get;set;} public object[] loop = {id, data, date}; } public enum status { nothing=0, instert=1, delete=2, edit=3 } </code></pre> <p>Situation has changed since yesterday but still, i'd like to index my class, my idea was by adding this line:</p> <pre><code>public object[] loop = {listA, listB, listC}; </code></pre> <p>to MainClass, archieving this goal, after changing the whole thing to an non static class it seems forbidden. also when i was trying this with a static class i cant adress my lists directly. could this be done any how?</p> <p>finaly i want to adress a specific property inside the list like this:</p> <pre><code>MainClass mc = new MainClass(); DateTime dt = mc.loop[2][5].loop[2]; </code></pre> <p>even if it would be nicer to do this without the loop property, like:</p> <pre><code>DateTime dt = mc[2][5][2]; </code></pre> <p>how i want to loop it finaly:</p> <pre><code>for(int i=0; i&lt;mc.loop.count(); i++) { for (int j=0; j&lt;mc.loop[i].Count(); i++) { switch(mc.loop[i][j].loop[3]) { case: delete doSomething1(mc.loop[i][j]) case: insert doSomething2(mc.loop[i][j]) case: edit doSomething3(mc.loop[i][j]) default break; } } } </code></pre>

    1. COYour code is fundamentally confused. Is your goal to set default values on the properties on the classes? Just do it in the constructors of `ClassA`, `ClassB`, etc. instead.

    2. COactualy my plan is to fill a class based copy of a multi-table sql-database with a short code, where i dont need to adress every class and its property individualy. instead i want to loop through the parent class and fill the lists of childclasses from its fitting datatable, so i need not only a loop, i also need to recognize which kind of class im using at the specific moment to take the specific sql-table

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.
