[Code]....
The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need. I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):

I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.
The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.
Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.
Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
