Combox and "lookup" values under Firemonkey [Edit]


How can I manage this ? :

I have a dataset with ID and Description fields.
I need the records to be displayed in a comboBox. Description need to be displayed. ID should be hidden.

I was able to display these records on a comboBox (using livebindings) but I can't find a way to get my ID value.
I'm doing this rigth now :

Here is how I've set my visual binding :
[BINDSOURCEDB].ID ----> [COMBOBOX].Item.LookupData
[BINDSOURCEDB].Description ----> [COMBOBOX].Item.Text

Here is my code (OnButonClick)

  if Assigned(ComboBox1.Selected) then
    if MyDataset.Locate('Description',ComboBox1.Selected.Text,[]) then
     label1.Text = MyDataset.FieldByName('ID').AsString;

How can I get .Item.LookupData ?
I'm right now doing a locate on my dataset ! This is cumbersome, isn't there another way to get my ID ?

"Edit" Vs"Edit Mask"
Are there any potential problems changing a datawindow date field from "edit" to "edit style" and vice versa? I have over 100 datawindows and who knows how many of them have date fields. Question is if I change the edit style from "Edit" to "Edit Mask" of dd/mmm/yyyy. Will this cause any kind of problems? TIA Well we changed ours from editmask to edit (partly because of the large numbers of bugs in edit masks in early builds of PB7, partly because our customers found editmasks unfriendly to use) and it didn't cause any problems. ...

Precedence of "where" ("of", "is", "will")?

Turid Have you tried to use the Modify command? I didn't look up the syntax for this but it would be something like : dw_1.Modify("column_name.dddw.Name='d_list'") dw_1.Modify("colun_name.dddw.DataColumn='list_id'") You will need to GetChild() on "column_name" to retrieve the list but I'm sure you get the idea.

"Me" is better than "You"
Yes I know, strings are frozen. But let me talk about it, I really can't get through the idea of a PC talkin to me. I consider my PC as an extension of myself, not a dumb companion who addresses Me as You. Yes there are times when I get angry with Him while I work and get wrong calculations etc.., but it really is my fault, Me using wrong istructions and eventually wanting to find someone else to blame, but it's Me. And yes, I consider Thunderbird my mail program, reading my mail on my PC as Me. So I personally like to have Me in the header bar as a compact address ...
