Hi experts,

I have a problem with Listboxes.

How can I assign the content of the currently selected item of a listbox to
a TEdit control?

I tried it like this

procedure TargetListBoxClick(Sender: TObject);
begin
 Edit1.Text:=TargetListbox.itemindex;
end;

but here Delphi complains about incompatible data types
(string and integer)

Any suggestions for a correct solution?

Hi

You need to do it like this:

Edit1.Text := TargetListBox.Items[TargetListBox.ItemIndex];

ListBox.ItemIndex is an Integer, but you need a string of text.  ListBox.Items[???] gives you the string you need.

Here is what you do...

DaEdit.Text := DaListBox.Items.Strings[DaListBox.ItemIndex];

I just added Listbox.Items.Strings[Listbox.ItemIndex];
because in Builder C++ you can not use only Items[] and need to use Item.Strings[]

Otherwise the idea is the same ;-)
