I have the following code, but only know how to show subelements of main element <code>"&lt;Invoice&gt;"</code>. How can query to show only <code>"&lt;Line&gt;"</code> elements for each <code>"&lt;InvoiceNum&gt;"</code> in datagrid:</p> <pre><code>filepath1 = "C:\Users\Documents\Teste.xml" Dim xml As XDocument = XDocument.Load(filepath1) Dim query = From xe In xml.Descendants("Invoice") Where xe.Element("InvoiceNum").Value = "153" Select New With { .Invoice = xe.Element("InvoiceNum").Value, .Date = xe.Element("Date").Value } DataGridView1.DataSource = query.ToArray </code></pre>
 

Querying!

An individual column

Larger individual text columns get their own page to allow for proper reading.
