>i have a child grid w table bufferring enabled. am using the setall\dynamicbackcolor method to highlight the current record. this works fine after a mouse click on the row, but when i append records (through the click event of a cmd button which is not on the grid) all the records(rows) in the grid are highlighted. it is like the if statement is firing in the setall. is this a buffering related problem?

It's related with iif() setting. Mailed you a sample grid class, check with that.
