VB dot net & data binding

I have a dropdown list control that I have bound to an SQL table called groups. The display, displays "group_name", which is a human readable text field.

I want to bind SelectedValue to group_id, which has a data type of uniqueidentifier (GUIDs), so I can later run an insert query using selected value:

INSERT INTO accounts (contact, phone, groupid) VALUES(?,?,?)

where those values are contact.text, phone.text, cboGroup.selectedvalue.

but when I do this, I get "Unspecified Error"....which is always greatly helpful.

What do I need to change to get this to work?Start Free Trial
