lExpr

Logical expression specifying if the Grid control uses Rushmore optimization.

Setting	Description
True (.T.)	The Grid control uses Rushmore optimization.
False (.F.)	(Default) The Grid control does not use Rushmore optimization.

Applies To: Grid Control

When Rushmore Optimization is enabled by setting the Optimize property to True (.T.), the set of matched records is refreshed during the following operations:

• When the Grid is initially populated
  
  
• When the Grid is activated
  
  
• When the Grid Refresh Method is called
  
  

Note:

As with any data manipulation command that can impact Rushmore optimization, you should be aware that actions taken against the Grid's data source could result in behavior that differs from when the Optimize property is set to False (.F.). For example, Rushmore optimization might trigger an implicit TABLEUPDATE to occur for a row buffered cursor. And an error may or may not occur depending on whether the record is blank or whether the cursor is a view.
