The best approach is to use declarative binding, in the selected item for sure you are using something like an Integer value to identify the item. I would use this combobox extension (try to define it inside your datatemplate):

I've opened a bug on the ComboBox so the owners can address this issue. Thanks for bringing this to our attention

Thanks Yifung,

Right now I'm trying to use the combo inside a Grid container... finally what I did is combine: LostFocus, with GotFocus on almost all the controls that I can, and even hiding the combo when you change the selection... by doing all this sort of combinations I almost manage to simulate a "LostFocus" working... (changed selection, hide combobox box, show a textblock).

I'm quite concerned about the Combobox, when we were talking about Beta 2 or even RC or early RTW, I can understand that it had so many bugs, but half year has passed and it's still an unstable component (and no way to convince a client to avoid using a combobox in their UI :-)).

Do you have plans to replace or fix this control on SL3?

Thanks

Braulio

I agree that that does not make sense.

What you can do is when the you get the LostFocus, get the newly focused element from the FocusManager. If this element is a popup and its Parent is the ComboBox then ignore the event.

I know that the fix on the combo were only applied to the DataGrid, but did anybody found other workarounds ?

Now I'm display dynamically a ComboBox inside a Grid control, but whenever I open the dropdown of the combo the LostFocus of that control is fired, does that makes sense? Is there any workaround?

thanks

Unfortunately, the fix was part of a mini release for the DataGrid only. Please see our announcement for details. Happy holidays

Wow !! That's excellent news. But the thing of the combo size happened as well outside the DataGrid (I mean the dropdown box size), It's there an update for the combo control as well?

Thanks

I just tested by remvoing the workaround and ComboBox now works properly. Also the bug with changing ComboBox list size seems to have been fixed as well! It now displays properly evertime list changes!

Good news that they have fixed the bug... bad news the fix breaks the current workaround :-(

Mmmm.... That this applies to the SDK? I mean the user will use the same lugin, but if I just download the latest SDK it will get updated isn't it?

Thanks

The above DataGrid bug (where the ComboBox closes immediately) has been addressed in the DataGrid December 2008 Release. The version released with Silverlight 2 would not work correctly with editing controls that opened Popups (like ComboBox or DatePicker). Opening the Popup would cause focus to leave the DataGrid, a control which automatically ends edit on LostFocus, thus preventing users from manipulating its contents.

Thanks a lot, I will give a try. It's a pity that we had waited so much for a combo, and control deployed is not well unit tested.

I see, I had misunderstood what you meant.

Hopefully the ComboBox will be improved so it is not necessary to extend every class you wish to use with a ComboBox.

But that is an interesting work around.

Thank you for sharing it.
