WPF Binding: Throttle the binding list's updates

I am binding the xamdatagrid to a list.But since there are too many updates on the list GUI get stuck.How can I stop these updates and refresh the grid after an interval(say 500 ms).Will Reactive extension's throttle method be useful?

You can use the DeferRefresh to defer the binding update until you're done making modifications to the collection:

using (collection.DeferRefresh())
{
    // Make changes to the collection
    ...
}

If the collection is being updated in real time, you could use a timer to update the binding at intervals:

private IDisposable _deferral;
private void refreshTimer_Tick(object sender, EventArgs e)
{
    if (_deferral != null)
        _deferral.Dispose();

    _deferral = collection.DeferRefresh();
}
