How to insert\Delete row without rebinding itemsource?

[Virendra]

Hi,
Is there a way to insert\delete row without rebinding itemsource?

In my application i have very complex/data heavy grid, which i don't want to rebind every time any row is inserted, deleted or updated.
Can we separate UI and datasource updation?

Thanks

Hi Virendra,

It is possible to avoid rebinding. However your data should follow some requirements.

Please use ObservableCollection or a collection implementing the INotifyCollectionChanged interface. as items source.

It you bind the ItemsSource property of the RadGridView to such collection , the RadGridView will automatically reflect changes in items , without the need to rebind.

Additionally I would recommend the objects in the collection to implement the INotifyProperty changed interface.
