Hi DK,
1. The only way RadGrid would not show its headers is when it is not actually bound to any data source (its DataSource is null) where it shows only the grid borders. Please see if you are actually binding your grid to a data source with no records, or you are not binding your grid at all.
2. If you are using custom data source operations for retrieving your data, you need to handle the Update/insert events manually. RadGrid's UpdateCommand and InsertCommand events are the place where you can get to the edited / inserted item data and upate your data source manually. The e.Item property of the event argument is the reference to the GridEditableItem that you are editing.
3. If your edit form is autogenerated, you can cast your e.Item property to a GridEditableItem and use its EditManager.GetColumnEditor("ColumnUniqueName") method to reference the column editor that you need to take the value from. More information on the topic can be found here and here. If, however, you are using some custom controls inside your edit form, you will need to find them by ID using the e.Item.FindControl() method in side the update/insert events.
