I have a radComboBox that is loaded from javascript when another combo's value is set, I use the itemsRequested event, the problem is that this combo that is loaded through javascript doesnt keep its value when posted, why is this and how can I solve it? any help is appreciated, thanks!
I forgot to mention that if I set the EnableLoadOnDemand property of the combo to true it keeps it value, but when I do this the combo filtering function no longer works.

Hi Roberto Yudice,
Could you please check if the second RadComboBox (that one populated with data via JavaScript) is read-only?
If it is read-only I can suggest you try setting the AllowCustomText property to “true”.
Then if you prefer to disable user typing in the RadComboBox input - handle the client-side OnClientLoad event as shown below:
Regarding your second question – Load-On-Demand and Filter features in fact make the same thing – they filter RadComboBox items. Load-On-Demand filters items at server-side and Filter does this at client-side.
As their functionalities overlap these two features by design are not intended to work together.
You can try removing the Filter and continue using Load-On-Demand.
Best wishes,
