ListBox doesn't fire oninserting and oninserted events

[gary]

Hi,
I have two list boxes inside a RadComboBox. RadListBoxSource is bound to an ObjectDataSource that load the listbox with names. The RadListBoxDestination is not bounded to anything, it just accepts the values that I select to transfer. The problem I am having is that when I select an Item from the RadListBoxSource, I break inside its ontransferring and ontransferred without ever breaking inside the RadListBoxDestination's oninserting and oninserted events.

I have witnessed the flow looking at the transfer demo and see that all the mentioned events get called; however, two do not get called.

Any Help will be appreciated.

Thanks in advance,
Gary

Hi gary,

In our demo the two RadListBox controls are bound to datasources. The datasources' events are fired on the server side - insert, delete and update.
Please consult with the following help article about RadListBox server side events.

All the best,
