Hello,

I am a newbie to IB Objects after years of Paxadox and dBase development. I
am working on an invoicing form using the following:

Delphi 4, IB 6.0 open source, IB Objects 4.2Fb

Table INV_HEADER
Primary key: ID
TIB_Query.SQL: SELECT * FROM INV_HEADER FOR UPDATE
.KeyLinks: INV_HEADER.ID

Table INV_DETAIL
Primary key: ID
Foreign key: HDR_ID, references INV_HEADER.ID
TIB_Query.SQL: SELECT * FROM INV_DETAIL FOR UPDATE
.KeyLinks: INV_DETAIL.ID
.MasterLinks: INV_DETAIL.HDR_ID=INV_HEADER.ID
.MasterSource: dsInvHeader

The form consists of several TIB_Edits for Header data and a TIB_Grid for
Detail data.

My Problem: When I open the form all header data appears to be fine, an id
is generated and data can be entered into edits, but the Detail grid appears
to be uneditable, I cannot enter any data. All necessary column headers
appear in the grid but nothing else.

I have read and studied forever, it seems; but I am stuck. Any help would be
so very appreciated.
