    <p>You have a couple options here. </p> <p><strong>1)</strong> You could let ServiceStack take care of this for you by using the high level Redis API. </p> <pre><code>public class Poco { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } ... // Client var client = new RedisClient("localhost", 6379); // This will store the object for you in a Redis hash. client.StoreAsHash(new Poco { Id = 1, Name = "Test Name", Description = "Test Description" }); // This will fetch it back for you. var result = client.GetFromHash&lt;Poco&gt;(1); </code></pre> <p>This approach will disconnect you from having to deal directly with the hashing particulars. ServiceStack will figure out everything for you and stuff the object you send it into a hash automatically. If you want to update that object, just send it a new one with the same ID.</p> <p>The flip-side of this is that you're giving up control of how your data is stored in Redis for an easier programming experience.</p> <p><strong>2)</strong> You handle all of the stuff yourself. There is no <em>SetAllEntriesToHash</em> function pre-built.</p> <pre><code>// Client var client = new RedisClient("localhost", 6379); // Clear all existing keys var keysToClear = new Dictionary&lt;string,string&gt;(); client.GetHashKeys("xxxxx").ForEach(k =&gt; keysToClear.Add(k, "")); client.SetRangeInHash("xxxxx", keysToClear); // Save new key/values. client.SetRangeInHash("xxxxx", new List&lt;KeyValuePair&lt;string, string&gt;&gt; { new KeyValuePair&lt;string, string&gt;("1", "value 1"), new KeyValuePair&lt;string, string&gt;("2", "value 2"), new KeyValuePair&lt;string, string&gt;("3", "value 3"), }); </code></pre> <p>Alternatively, it may be easier just to delete and recreate the hash.</p> <p>I would also like to draw your attention to <strong>RedisNativeClient</strong>. It allows you to run Redis commands that directly map to <a href="http://redis.io/commands" rel="nofollow">http://redis.io/commands</a>.</p>

    2. COYup, that's a delete and re-add. Probably the easiest.

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.
