Binding in ItemHeaderTemplates

[Adam12]

It appears as though the ItemHeader items don't get their DataContext properties set.  Consequently it doesn't appear to be possible to bind to the ViewModel from within an ItemHeaderTemplate.

Is this right? Is there any way to work around it?

Thanks

Hello Adam,

I am not quite sure that I correctly understand the case. Are you setting the ListHeaderTemplate and ListHeader properties and not getting the desired behavior? In fact, we do not have a ItemHeaderTemplate property in RadDataBoundListBox.

Looking forward to receiving further details on your scenario.

Kind regards,

Sorry I meant ListHeaderTemplate.  Also I didn't realize you had to set ItemHeaderContent explicitly.  I assumed that it would just pick up the DataContext from the listbox.

Binding the ItemHeaderContent works a treat, thanks.

Hi Adam12,

Thanks for writing back.

Indeed, you will have to set the DataContext or the ItemHeaderContent explicitly since visual containers are reused in RadDataBoundListBox and thus their DataContext is reset according to the business object behing the corresponding visual container. This is part of our UI virtualization mechanism.

I am happy that you have managed to resolve the case. We will consider the thread closed.

Do not hesitate to get back to us in case you have further questions or need assistance.
