I've got a form with a bunch of RadioGroups. I created an array of
RadioGroups to make it easier to write code to work with the group. I've
also got a ComboBox in which the user can choose whether s/he would like to
display 2, 3, or 4 items (i.e., select "2" and all the RadioGroups will have
2 and 1 as their items; select "3" and they'll all display 3, 2, and 1).
The ComboBox OnChange event begins by clearing all the RadioGroups, and then
adding items back (with the items added depending upon what the user
selected in the ComboBox):
for i := 1 to 19 do
begin
gRadioArray[i].Items.Clear;
with cbxPerformanceLevels do
//add items here, depending on what user selected
end;
The code works fine, and it's simple. The problem is that it's slow. On my
machine I can watch each RadioGroup be cleared, one at a time, before items
are added in.
Do you have any ideas about a faster way to do this?
