Gothca....so do you have the value member field in the BO coming back as a time span?  You might consider creating a custom property on the BO from which you are populating which returns a TimeSpan value like you are doing in your manual sample, this way you are ensured that it is typed as a TimeSpan.

In a nutshell, when  I update the form, the column value attached to the timespan combo is not being saved? I have a ton of combos enums, and others in the application which are fine. This one is just not getting the timespan value?

Well, let's dig a little deeper...this is the ONLY way I generally ever populate a combo, so give me some more details or post a quick sample so we can see what you might be doing that is not working for you.  Also, there are quite a few samples throughout the different samples that does this, so you might want to look at these as well.

Private Sub PopulateReminderCombo()

Dim loTable As New DataTable()

Dim loRow As DataRow

'-- Create the table structure

loTable.Columns.Add("Display", GetType(String))

loTable.Columns.Add("DropDown", GetType(String))

loTable.Columns.Add("Value", GetType(TimeSpan))

'-- Add some rows

loRow.Item("Display") = "0 minutes"

loRow.Item("DropDown") = "0 minutes"

loRow.Item("Value") = (New TimeSpan(0, 5, 0))

loTable.Rows.Add(loRow)

loRow = loTable.NewRow()

loRow.Item("Display") = "5 minutes"

loRow.Item("DropDown") = "5 minutes"

loRow.Item("Value") = (New TimeSpan(0, 5, 0))

loTable.Rows.Add(loRow)
