Each passing by the great god:
I inherited a new class from stringgrid, used to draw the custom format form; To rewrite drawcell, main is to draw the rectangle and display text,
Began to display is normal, but click on the scroll bar or scroll up and down (this time should be triggered by redrawing?) , there will be the color of the rectangle and fill will be disorder, don't know where this is not to deal with,
Excuse me, is there a way to trigger all of the cells in the stringgrid all drawing side?
thank you

Click on the scroll bar up and down or rolling the mouse with an APi function in the scroll ScrollWindowEx

If forced drawing will be flashing
