I have been using the below code for some time but it seems it is quite slow, what is a way to just change the grid colors for the row the user changes, rather than have this code run on the entire grid with every row change.

Thisform.Grid1.SetAll("DynamicForeColor",; 
"IIF((<Var> == ALLTRIM(<tablename>.<fieldname>) AND <boolean1 field>) OR ;
     (<Var> == ALLTRIM(<tablename>.<fieldname>) AND <boolean2 field>), RGB(128,64,64), RGB(255,255,255))",;
"Column") 

Thisform.Grid1.SetAll("DynamicBackColor",; 
"IIF((<Var> == ALLTRIM(<tablename>.<fieldname>) AND <boolean1 field>) OR ;
     (<Var> == ALLTRIM(<tablename>.<fieldname>) AND <boolean2 field>), RGB(128,64,64), RGB(255,255,255))",;
"Column") 

Should I put the color code on AfterRowColumnChange?
