Hi Nadeshda
Sorry, your answer is wrong and the link you referenced is not related to my Problem.
I have configured the Combobox as an auto-complete Combobox with remote data source. So after a postback from the Server the Combobox does not contain any item in ist datasource because there wasn’t yet a request to load items from the backend. Calling myComboBox.jqxComboBox(‘getItem’, myid) Returns null!
I guess there isn’t a solution for my Problem already implemented in the Combobox and I have to solve it on another way.
Anyway Thank you.
Adrian
