I hav placed a c1flexgrid inside splitpanel2 in a splitcontainer with vertical orientation. after placing a linklabel to increment and decrement the splitter distance of panel one(loop for increment and decrement)), i got the c1 flexgrid scrolled along with the panel.. but when i am decrementing the splitter distance, c1flexgrid shows a small lag whn scrolling up. moreoever, there comes a small black line whn the flex grid goes up..

plz somebody help me to get rid of that black line when it goes up...

Thanks in advance
