Hi is there any way I can identify the last DataRow in a table.
What I would like to do is list some items seperated by a comma apart from the last item.

such as:

For Each grandchildRow As DataRow In childRow.GetChildRows("GrandChildren")

If not last row
CategoryLabel.Text = (grandchildRow("DCategory").ToString()) + ", "
else if last row
CategoryLabel.Text = (grandchildRow("DCategory").ToString())
Next

But what do I put to identify the last row?

Cheers

same result:
Dim row As DataRow = table.Rows(table.Rows.Count - 1) 'Where Table Your Table Name
        Console.WriteLine(row("ColumnName"))
0

You can use count to compare, like this:

Dim iCount as Integer
Dim iRows as Integer = childRow.GetChildRows.Count
For Each grandchildRow As DataRow In childRow.GetChildRows("GrandChildren")
iCount += 1
If iCount < iRows then
CategoryLabel.Text = (grandchildRow("DCategory").ToString()) + ", "
else
CategoryLabel.Text = (grandchildRow("DCategory").ToString())
 End If
Next
