Update grid when data source changes w/o INotifyPropertyChanged

[JP]

Hello,

I am binding the the RadGridView to a collection of objects that do not implement INotifyPropertyChanged or INotifyCollectionChanged.  Specifically, I'm using the WorkItemCollection and WorkItem objects from Microsoft's Team Foundation Server object model.  The WorkItem object has an event that is raised whenever a field is modified, so I do have a way of knowing exactly when an object changes and which field has changed.  Given that, is there a way to manually update the grid without rebinding the entire grid?  Perhaps by just updating a single row or cell?

Thanks,

Joel

Hi Joel,

I don't think there is a nice way to do that. Maybe the most elegant way to implement that is to use your own observable collection referencing WorkItemCollection and contains objects wrapping the WorkItem ones and implementing INotifyPropertyChanged. This way you can:
 * Handle collection change events raised by WorkItemCollection and raise CollectionChanged events for your observable collection;
 * Handle work item property changes raised by WorkItem objects and raise PropertyChanged events from your wrapper objects.

I hope that does not sound too scary.

Hi Hristo,

Thanks for your reply.  I figured that what you suggested would be the route I would have to go.  I just thought that I'd ask the experts to make sure that there wasn't some feature of the grid or some easy method that I was overlooking.

Thanks,

Joel
