Hi,
I'm trying to implement a monitoring gridview that have a column of a time counter that increments in each second. 
For now the only solution that i came up with is to do a DispatcherTimer initiating foreach that increment each object and then rebind the grid, which of course is an awful performance hit.
Any suggestions?

Hello,

 If your data item is INotifyPropertyChanged you can change only desired properties and the grid cells will be updated immediately.

Hi Shmuel Tal,

 If your data model implements INotifyPropertyChanged, you won't need to call Rebind() on the grid. Every time your timer updates your data object, the GridView will refresh only that part of its UI that is affected by the change.

Hello Shmuel Tal,

 Could you please elaborate a bit more on your question? If your timer updates the data item, why would you need to get it when the cell for the property is changing?

Sincerely yours,
