Hi all,
Microsoft Excel can't show large amount of tabular data for example > 1000*1000
I want to show larger tabular data and then like in excel formating their cells and save and load it.
but here mathematical calculations are not needed and just style should be save and load.
my idea is using data gridview

but there are some questions :
1. Can bind very large file to datagridview?! and then user doesn't feel borely when scroll on it( how much delay for loading data)?
2. Can assign styling format to each cell or grouping of cells alike excel for example font, forecolor, backcolor and borders?!
3. now can save and load it's display style?

Data are Integers ...

excuse me for poor english writing and please help me
