Hello Gloria.

How can I change the BackColor and ForeColor of row that is selected by clicking the check box?

This sample code assumes that the column with the check box is bound to a field named lSelected in the grid's RecordSource:

*** Set up for highlighting ALL Selected Rows
This.SetAll( 'DynamicForeColor', ;
	'IIF( lSelected, RGB( 0, 0, 128 ), RGB( 0, 0, 0 ) )', 'COLUMN' )
This.SetAll( 'DynamicBackColor', ;
	'IIF( lSelected, RGB( 0,255,255 ), RGB( 255, 255, 255 ) )', 'COLUMN' )
