in the database I have some number, like: 1, 2, 3, 999,999 - from above to down
but if you want to sort up, then if 999 is above the last number not 999 then number has to be number + 1, so in this case 3 became 4, but if you have 4 it will be 5
do you have maybe something for it
if (medicijn.Volgorde == 999)
{
//medicijn.Volgorde = ( 999 - medicijn.Volgorde) + 1;
medicijn.Volgorde = medicijn.Volgorde;
}
