Hi,
I want to add three header row to DatagridView.
Row1 -> Columns Header -> 2013,2014,2015 Years (Merge Months Count = 12)
Row2 -> Columns Header -> 1,2,3,...,12 Months (Merge Days of Month = 28,30, or 31)
Row3 -> Columns Header -> 1,2,3,...,28,29,30,31 Days of Month (I calculate this with DayInMonth(Years,Months)
|------------------------------------------2015------------------------------------------| Row1 Header
|--------------------------------------------1--------------------------------------------| Row2 Header
|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31| Row3 Header
|-----------------------------------------2015---------------------------------| Row1 Header Continue
|--------------------------------------------2----------------------------------| Row2 Header Continue
|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28| Row3 Header Continue
I want to like these rows and headers.
I use VB.NET 2012
