How Do I Create Rows That Can Expand/Contract?
This lesson will show you how to make a Data Grid form with rows that expand and contract when clicking on an arrow.
Expanding and Contracting Rows
Setting the Data Grid Properties
Updating the Row Behavior Script
In the LayoutControl message you need to readjust the position of the controls and background graphic based on whether or not the row is expanded or contracted. Since the "fixed row height" property is set to false the Data Grid computes the total height of the data based on the height of each row after calling LayoutControl.
