I don't know the dblookupcombobox too well but looking at the help what I'd do is this.

1. Use the OnClick event
2. Iterate through the items in the list using a FOR loop, looking for a match. When you get a match, you've got your index value

is there any propierti that tell me what is the index value...............?

TheNeil

Not that I can see. That's why you'd have to do the search yourself. It's not a big job though - You know the text selected and I assume you can gain access to the list of items so you just use something like the following

iIndex := -1;
FOR iCount := 0 TO <No Items>
DO
IF ComboBox1.Text = ComboBox1.Items[iCount]
THEN
iIndex := iCount;

You can't read itemIndex (x) and with that int check the items array? (items[x])?

I was using the standard Combobox as an example

For standard comboboxes,

if( ComboBox1.ItemIndex > -1 ) then
ShowMessage( ComboBox1.Items[ ComboBox1.ItemIndex ] ) ;

works...don't know about dbLookupComboBoxes...sorry...
