如何在动态生成的DBComboBox中添加数值

Question

我的代码
public
  COMBOBOX : TDBCOMBOBOX;
....   COMBOBOX:= TDBCombobox.Create(FormLookUp);
   
   COMBOBOX.Parent :=  FormLookUp.DBGrid1;
   COMBOBOX.Left:=10;
   COMBOBOX.Top:=16+18*i;
   COMBOBOX.width:=68;   COMBOBOX.Items.Add('asdf');
   为什么不能添加进去数值啊！

Answer 1

COMBOBOX.Items.Add(Table1.FielfByname('sdf').Asstring);

Answer 2

COMBOBOX是TDBCombobox类，因此，你要首先指定COMBOBOX。DataSource和DataField属性，才可以

Answer 3

COMBOBOX.Items.Add(Table1.FielfByname('sdf').Asstring);
我的哪个只是个例子 
我自己写的是
COMBOBOX.Items.Add(Table1.FielfByname('sdf').value);
这区别大吗   ？

Answer 4
