Combobox and Ajax

  
I need some help

I am trying that On Change of one choise of a combobox, using ajax a can update the expression that is in the blue strip with the content of the field model form the same entitie that i use to fil the combobox.



Nothing is resulting !!!

I included one testes file  to help.

Hi Alberto,

Can't find your test file. If you share it perhaps we can help you.

Cheers
Sorry!
Hi Alberto,

On the expression you're using the value from the form ViagenForm.Record.Carros.Modelo but on the Action1 your're executing a completly different query that's not binded to the form.

You may need either to assign a value from the query to the value of the form first.


Thanks for your support. It works.

But know a new question.

The first time i change the option in the combo box, it update the expression. But if I made another change (already in the same editon of the form) nothing occurs !!!


TIA
Well!! I checked with the debuger and it trigers everytime something change on combobox... I must check my logic .
