Hello Rahul,

I am afraid that I was unable to locally replicate the described issue, due to some missing references. Especially the getAdditionalConditions method which is responsible for data supply for the RadComboBox.

This is why, I would like to ask you to submit a support ticket, along with a runnable sample attached, where the experienced issue is replicable. Thus, we will be able to locally replicate the problem and suggest you the proper approach.

Regards,
Nencho
