Well actually... I think I fixed it..
In the DataGridComboColumnStyle Class I added this
Public Event ColumnComboBoxSelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
....and then in the Event that has the SetColumnValueAtRow (which is ComboChanged) I Raised that event..
...and then, in the Form Class, when setting the properties for this style and adding it to the DataGridTableStyle I added a handler
'COMBOBOX
Dim statestyle As New DataGridComboColumnStyle(ds.Tables("States"), "State", "State")
statestyle.MappingName = "State"
statestyle.HeaderText = "States"
ts.GridColumnStyles.Add(statestyle)
AddHandler countrystyle.ColumnComboBoxSelectedIndexChanged, AddressOf ColumnComboBox_SelectedIndexChanged
And then
Public Sub ColumnComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
MsgBox(CType(sender, DataGridCombo).SelectedValue)
End Sub
Which Worked fine

Then I can take that Value and search for a Row in the ComboBox Source and then grab whatever mpre fields I need and add to the cells on the same row in the grid
This wouldn't give me any problems later on or?
