    <p>I am currently working on a project which creates a dictionary with an int index of the instance and a complex type as the value. Since this is a huge school project I do not want to post a ton of code as I have a logic problem rather than a "I need code". I'll try to be as clear as I can and if there is something I need to explain better please let me know.</p> <p>First off. I have a dictionary in my server:</p> <pre><code>private Dictionary&lt;int,List&lt;complexType&gt;&gt; dictName = new Dictionary&lt;int,List&lt;complexType&gt;&gt; </code></pre> <p>Every time a client starts up it registers with the dictionary (i create a blank complex type to instantiate it then i load the dictionary):</p> <pre><code>List&lt;complexType&gt; temp = null; dictName.Add(id,temp) </code></pre> <p>Then when the time comes that I want to add to the list for a particular instance I do this:</p> <pre><code>complexType myItem = new complexType(); dictName[id].Add(myItem); </code></pre> <p>When I run this code I get an error when a second client tries to run: </p> <blockquote> <p>"An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll. Additional information: Exception has been thrown by the target of an invocation.</p> </blockquote> <p>Now this happens when the second user hits: <code>dictName.Add(id,temp)</code> from the first part. </p> <p>If i change the instantiation of temp to <code>List&lt;complexType&gt; temp = new List&lt;complexType&gt;();</code></p> <p>then it passes that spot but I get the same error again when it updates the clients.</p> <p>I am currently using this way of passing data with int and string (dictionary) and they work fine but when I added in a List of a complex type in the dictionary I got the above error.</p> <p>If anyone has any suggestions I would greatly appreciate it. I'm hoping it has something to do with my initial load of a blank list. If there is anything else you need to know please Ask Thanks!</p>

    1. COWhat's the exception? The posted exception *should* have an InnerException property. Can you tell us what it is?

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.
