Got a simple project I've got a master detail relationship on a form, with a
datamodule (dml1)
Master
table: tblStudent
datasource:dsStudent
Detail
table:Parent
dtasource:dsParent

On the tblStudent (NewReocrd) if got the following code:

 void __fastcall Tdml1::tblStudentNewRecord(TDataSet *DataSet)
{
tblNewStudent->Open();
try
{
tblNewStudent->Edit();
tblStudentStud_no->Value = tblNewStudentNewKey->Value;
tblNewStudentNewKey->Value = tblNewStudentNewKey->Value + 1;
tblNewStudent->Post();
tblNewStudent->Close();
}
catch(...)
{
tblNewStudent->Close();
}
tblStudentReg_Date->Value = Date();
}

As soon as I run the form and press the save button which post(); the
records it  either gives a "tblParent not in insert or edit mode"  or it
gives master reord missing.

I've made sure that on (activate) of the student form that it put the tables
open and insert mode and when I press the save button that it edit and post.
