Possible Grid change

2009-05-29T05:41:00.001-07:00

I am thinking of changing the way the grid works buy adding a PageIndexChanged Event. I would like to know everyones opinionThis will break everybody code , but I think it will pay off in the long run. The benefits of the change are:- You will be able to use two grids with paging on one page.(only possible today with hacks)- the code will be more similar to the one used on the regular gridview.-
