Hi Guys,
I am using Data Grid in Windows Form. I am displaying information in data grid. I have also used Button type column to provide delete facility. I have also applied Alternate Row Style as back color as Light Gray. All works fine.The only problem is at run time what happens is the Light Gray color of alternate rows is also applied to Button's Back color. So it doesn't look good and I want to keep all buttons back color in grid same as I specified at design time (i.e. System Control color)

I am locked here..pl help me out

Thanks
