    <p>Fairly new to programming. I just can't wrap my head around how to get this to work in reverse. I have a save method and an open method. Save:</p> <pre><code>IDictionary&lt;string, IDictionary&lt;string, object&gt;&gt; pluginStates = new Dictionary&lt;string, IDictionary&lt;string, object&gt;&gt;(); signaller.RaiseSaveRequest(pluginStates); &lt;--goes out and gets packed plugins //loop through plugins to get values and types //holds all of the plugin arrays Dictionary&lt;string, object&gt; dictProjectState = new Dictionary&lt;string, object&gt;(); foreach (KeyValuePair&lt;string,IDictionary&lt;string,object&gt;&gt; plugin in pluginStates) { //holds jsonRepresented values Dictionary&lt;string, object&gt; dictJsonRep = new Dictionary&lt;string, object&gt;(); //holds object types Dictionary&lt;string, object&gt; dictObjRep = new Dictionary&lt;string, object&gt;(); object[] arrayDictHolder = new object[2]; //holds all of the dictionaries string pluginKey = plugin.Key; IDictionary&lt;string, object&gt; pluginValue = new Dictionary&lt;string, object&gt;(); pluginValue = plugin.Value; foreach (KeyValuePair&lt;string, object&gt; element in pluginValue) { string jsonRepresentation = JsonConvert.SerializeObject(element); object objType = element.Value.GetType().ToString(); dictJsonRep.Add(element.Key, jsonRepresentation); dictObjRep.Add(element.Key, objType); } arrayDictHolder[0] = dictJsonRep; arrayDictHolder[1] = dictObjRep; dictProjectState.Add(pluginKey, arrayDictHolder); } JsonSerializer serializer = new JsonSerializer(); using (StreamWriter sw = new StreamWriter(strPathName)) using (JsonWriter writer = new JsonTextWriter(sw)) { serializer.Serialize(writer, dictProjectState); } </code></pre> <p>So, when someone saves, an event handler goes out and gets the packedState of each plugin, adds it to a dictionary pluginStates. I then go through each plugin in the pluginStates, adding the key, and json string version of the value to 1 dictionary and the key, object type to another dictionary, add those 2 dictionaries to an array and then pack up a dictionary that contains the pluginKey and the array for each plugin. Reasoning: when deserializing, I'm hitting problems going from JArray to type DataTable and other types that are within the dictionary that gets passed back to the plugin to unpack itself upon opening. I'm trying to figure out how to reverse this, so that when user opens project, I have the dictProjectState and need to bring it all the way back through the code to end up with 1 dictionary containing the plugins. How do I mirror this save in the open?? Thanks!</p>

    1. COJust a note: You shouldn't initialize `pluginValue` to a new dictionary, since you're assigning it to `plugin.Value` in the next line. You can combine those two lines into a single line: `IDictionary<string, object> pluginValue = plugin.Value;`

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.
