D and a bazillion of small objects

[Kagamin]

You can use another design: feed your control with your items collection and interface like

string opIndex(size_t item, size_t subItem);
string opIndexAssign(size_t item, size_t subItem, string newValue);
void sort(size_t subItem, bool asc=true);

which will be used by the control to present the items. Then implement and fill your collection as you want.
