    <p>Sorry if the description is poor, but I don't know how else to put this... But here is an example of the XML structure </p> <pre><code>&lt;?xml version=”1.0” encoding=”UTF-8”&gt; &lt;Response xmlns="http://www.blah.com"&gt; &lt;searchResult&gt; &lt;info&gt; &lt;firstName&gt;John&lt;/firstName&gt; &lt;lastName&gt;Doe&lt;/lastName&gt; &lt;totalCharges&gt;100.00&lt;/totalCharges&gt; &lt;nonPaymentCode&gt;99999&lt;/nonPaymentCode&gt; &lt;/info&gt; &lt;info&gt; &lt;firstName&gt;Susan&lt;/firstName&gt; &lt;lastName&gt;Doe&lt;/lastName&gt; &lt;totalCharges&gt;1000.00&lt;/totalCharges&gt; &lt;errorCodes&gt; &lt;errorCode&gt;12345&lt;/errorCode&gt; &lt;/errorCodes&gt; &lt;/info&gt; &lt;info&gt; &lt;firstName&gt;Peter&lt;/firstName&gt; &lt;lastName&gt;Doe&lt;/lastName&gt; &lt;totalCharges&gt;10.00&lt;/totalCharges&gt; &lt;errorCodes&gt; &lt;errorCode&gt;12345&lt;/errorCode&gt; &lt;errorCode&gt;54321&lt;/errorCode&gt; &lt;errorCode&gt;85246&lt;/errorCode&gt; &lt;/errorCodes&gt; &lt;/info&gt; &lt;/searchResult&gt; &lt;/claimInquiryResponse&gt; </code></pre> <p>I have transformed this into a dataset in order to access the information as a datatable. But my problem is trying to get the errorCodes. I was trying to figure this out by checking the relationship of the tables. Because I have to figure out what error codes are associated with what person, in order to display them properly. I cannot control the XML structure, and everything is optional in order to reduce excess bandwidth so changing it is not an option at this point. But here is an example of what I have done:</p> <pre><code>For Each rel As DataRelation In ds.Tables(i).ChildRelations If rel.Nested Then Dim temp As New DataTable temp = rel.ChildTable For Each relationship As DataRelation In temp.ChildRelations For Each row As DataRow In relationship.ChildTable.Rows For Each column As DataColumn In relationship.ChildTable.Columns rowValues &amp;= column.ColumnName &amp; "-" &amp; row(column.ColumnName) &amp; "-" &amp; relationship.RelationName &amp; vbCrLf Next Next Next End If Next </code></pre> <p>This gives me the actual values of the data inside of errorCodes table. but I can't figure out how to link it back to what row/person it was associated with. The indexes the relationship generate are built off of their occurance (for instance the error codes for susan will be 0 and for peter it will be 1), not relating to their location in the XML. </p> <p>I am either doing this wrong or looking at this data incorrectly. I know I can use a XML reader to get all this, but the data is already in the dataset, and I feel like learning something new. so only suggest it as a last resort please. </p> <p>thanks in advance! </p>

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.
