I want to change these values with DataFormatString properties in Gridview.
1.000000 --> 1 --> Deleting all digits after .
366705.000000 --> 366,705 --> Deleting all digits after . and put the comma for seperate.
12.830000 --> %12,83 --> Delete last 4 digits after . and put % (% is optinal not must)
BTW, Is there any link to suggest me otherwise DataFormatString. I analyze very well this page but sometimes still can't find what I need about data format string.
