[Axapta-Knowledge-Village] Help on Header-Line Style Form Development

[XeN]

I have created two tables with master-detail relationship, and put them 
on a form which consist of two groups, and two grids and outer-join 
relation between two tables. The problem is, when I press the New 
button on toolbar, both grids create a new record whereas the same-
style Purchase and Sales forms of axapta do not. How can it be solved?
