pre-selection of a listbox item after clicking a button

[ra_be]

Hello,

I have a listbox with a lot of item to choose. Now I have to implement a button that the listbox will scroll down to a particular item of the listbox.

E.g. click on button1 -> the listbox scrolls automatically to item no. 20 (and select it)

click on button 2 -> the listbox scroll automatically to item no. 30 (and selcect it)

Does anyone have an idea?

Thanks.

Regards,

ra_be

Hi ra_be,

Here's a simplified sample that should help you.

Thanks. Actually it is too easy...

So how does that work accessing the specified value without using "boundItem."

I've just been playing around with something similar and couldn't get it to work with just using rawValue (I've got a couple of recent threads about it on here).

[ra_be]

The code is "Listbox.rawValue = 1;" or "Listbox.rawValue = 27;".

But you have to define the "element values" before. Click on your listbox, then object, then connection. Just tick the "Define elements value" and the code should work. (I am not quite sure with names and captions as I am not using an English version of LSD.)

Using the boundItem method is probably a better way of doing it for the examples you posted Jono, especially for the switch statement. ra_be's sounded like a simple one-off. ra_be, good catch on calling out that you have to specify the item values, I didn't think to mention that.
