Getting Started with DataGrid and another datagrid form

[Douglas Ruisaard]

Ah ... I think I can answer this.  Basically, you don't *have* to code the "Layout Control" beyond the recommended:

  set the rect of graphic "Background" of me to pControlRect

and even that may be, technically, optional.

The handler is there (I believe) as a method by which you can "dynamically" change the layout of a row (using grid FORMS.. the Behavior script is NOT used for TABLE grids) and/or being able to programmatically alter the layout of a row without going through the whole "Edit Group" method.

Not sure what you mean or asking about the "WYSIG panel" (never seen "WYSIG" .. only know "WYSIWYG" ... same thing?) ... do you mean the Row Template?
