    <p>Let me know if I should delete the old post, but perhaps someone wants to read it. </p> <p>The way to do a "words to look for" inside the regex is like this:</p> <pre><code>regex = @"(Key1|Key2|Key3|LastName|FirstName|Etc):" </code></pre> <p>What you are doing probably isn't worth the effort in a regex, though it can <em>probably</em> be done the way you want (still not 100% clear on requirements, though). It involves looking ahead to the next match, and stopping at that point.</p> <p>Here is a re-write as a regex + regular functional code that should do the trick. It doesn't care about spaces, so if you ask for "Key2" like below, it will separate it from the value. </p> <pre><code>string[] keys = {"Key1", "Key2", "Key3"}; string source = "Key1:Value1Key2: ValueAnd A: To Test Key3: Something"; FindKeys(keys, source); private void FindKeys(IEnumerable&lt;string&gt; keywords, string source) { var found = new Dictionary&lt;string, string&gt;(10); var keys = string.Join("|", keywords.ToArray()); var matches = Regex.Matches(source, @"(?&lt;key&gt;" + keys + "):", RegexOptions.IgnoreCase); foreach (Match m in matches) { var key = m.Groups["key"].ToString(); var start = m.Index + m.Length; var nx = m.NextMatch(); var end = (nx.Success ? nx.Index : source.Length); found.Add(key, source.Substring(start, end - start)); } foreach (var n in found) { Console.WriteLine("Key={0}, Value={1}", n.Key, n.Value); } } </code></pre> <p>And the output from this is:</p> <pre><code>Key=Key1, Value=Value1 Key=Key2, Value= ValueAnd A: To Test Key=Key3, Value= Something </code></pre>

    1. CO@Andrew, nice one! The "Key2: ValueAnd A:" Space in the Value was exactly what the problem was. thanks!

    2. COGlad I could help. I'm still trying to figure out a good clean regex way to do this, maybe with a simple loop, but i can only get 70% "rightness" so far.

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.
