Show selected xml in gridview from linq query

I have this code return all elements of each "line" element in  "InvoiceNum". But returns each one at a time. I need to return all elements of each line (ProductId, Description,Quantity) to a unique row and then show in datagridview.

<Documents>
	   <Sales>
		<Total>81678.600000</Total>
		<Invoice>
			<InvoiceNum>153</InvoiceNum>
			<Date>2013-03-01</Date>
			<Customer>2589</Customer>
			<Line>
				<ProductId>AT.02-2584</ProductId>
				<Description>Product 1</Description>
				<Quantity>1.000</Quantity>
				<UnitPrice>265.140000</UnitPrice>
			</Line>
		</Invoice>		
		<Invoice>
			<InvoiceNum>154</InvoiceNum>
			<Date>2013-03-01</Date>
			<Customer>2589</Customer>
			<Line>
				<ProductId>AT.02-2584</ProductId>
				<Description>Product 1</Description>
				<Quantity>1.000</Quantity>
				<UnitPrice>265.140000</UnitPrice>
			</Line>
                        <Line>
				<ProductId>AT.02-2599</ProductId>
				<Description>Product 2</Description>
				<Quantity>1.000</Quantity>
				<UnitPrice>85.100000</UnitPrice>
			</Line>
		</Invoice>	
	</Sales>
</Documents>

Select allOpen in new window

Dim xdoc As XDocument = XDocument.Load("C:\Test\test.xml")

        Dim query = (From xe In xdoc.Descendants("Invoice") _
          Where (xe.Element("InvoiceNum").Value = "154") _
          From Elemento In xe.Elements("Line").Descendants _
          Select Elemento.Value).ToList

        If query.Any() Then
            For Each Elemento In query
                MsgBox(Elemento)
            Next
        End If
