BringRecordIntoView -> Lock
posted

 Hi,

I use the method "BringRecordIntoView" andin some cases, it LOCK the application !!!! The method does not respond !

Here is some code:

Dispatcher.Invoke(DispatcherPriority.Send,
                                        (DelegateInvoker)delegate { AsyncMediaSelectionChanged(); });

void AsyncMediaSelectionChanged()
{

DataRecord selectedRecord = xdgMedias.GetRecordFromDataItem(Host.MediaService.CurrentMedia, false);
                if (selectedRecord != null)
                        xdgMedias.BringRecordIntoView(selectedRecord);

}

 

Please, can you help me ?

    The same problem here, with XamDataGrid v10.1

    I am calling BringRecordIntoView() from XamDataGrid.Records.CollectionChanged event handler. Occasionally the grid goes into an infinite loop, freezes the application and maxes out the CPU.

    I do not have a deterministic scenario for reproducing the problem, but it happens quite often on different PCs. Grid has the group by, filtering and fixed record features enabled. Rows are of variable height and sized to contents.

    Included below is a partial call stack taken when the problem was occurring.

    Can you please have a look and advise?
