I am facing a weird issue that I am able to reproduce on you demo page (with Chrome and Firefox).
Basically sometime the get_selectedItem() method return null while an item has been checked.
Here is the way to reproduce it:
Go to the WCF load-on-demand demo here:
With your mouse, click on the arrow of the RadCombobox to display to the drop down panel and select for example the third item ‘Ana Trujillo’.
The drop down panel closes.
Now in the console of the browser’s developer tool, type:
You can notice the returned value is not null.
Then click again on the arrow to show the drop down panel and after that directly click on ‘Annette Roulet’.
The drop down closes again.
Go back to the console et re-evaluate the selected item.
You can notice the returned value is null whereas an item is graphically selected.
Are you aware of that?
Do you know a workaround?
