I have a datagridview comboboxcolumn that has a valuemember and a displaymember.  The valuemember is saved in the database and I need to use displaymember for a calculation.  All I can seem to get is the valuemember for the database.  

Somevariable = CDbl(.Cells("column_name").Value.ToString) --> This gets me the valuemember.  What can I do to get the Displaymember and assign its value to a variable?

Try this:
Dim oCell As DataGridViewComboBoxCell = CType(.Cells("column_name", DataGridViewComboBoxCell)
if oCell IsNot Nothing Then
    Somevariable = oCell.DisplayMember
End If

DisplayMember will give you the name of the property (or column) in the datasource that the control is bound to.

To get the Text that is displayed in the cell, you could use the Value property and do a lookup for the corresponding Display Value in the datasource.

e.g.

Somevariable = CDbl(.Cells("column_name").Value.ToString)
''lookup the Display value in the datasource using the Value
Dim dr As DataRow = ds.Tables.Item(0).Rows.Find(Somevariable)
Dim DisplayValue As String = dr.Item("SomeColumn")
