    GridViewSelectColumn seems to be very slow when selecting a very large list of items. From the looks of it, it appears to be issuing a property changed notification for each item individually.

    Is there a way to speed it up?

    Hello Patrick,

    Could you provide a bit more details on your setup, so I'm sure to test the same scenario locally? I profiled a simple app with large amounts of items (around 500K), and although there are slight delays, those don't appear to be significant. Please elaborate on these question:
    - What the amount of data in terms of items count and column count.
    - What's your RadGridView setup (e.g. automatic or manual generation of columns, are you using custom columns, which GroupRenderMode, etc.). A snippet with the control's XAML markup may be helpful.
    - From your question, my presumption is you're using the select column with Extended or Multiple SelectionMode, please specify which one exactly.

    Any additional details you feel may be relevant will also be appreciated.
