If your collection is INotifyCollectionChanged the grid will show new record automatically - in all other situations you can call Rebind() method.

Also be careful when you have filters applied to your collection as this could result in a refresh not working if you just issue a Rebind. Make sure you re apply any filter you added and if this means you don't need the rebind then don't use the rebind but your own filter instead.

Hello,
The approach would be similar :
In your Record objects , you should implement the INotifyPropertyChanged interface.
Generally RadGridView would respect both: INotifyCollectionChanged and INotifyPropertyChanged interfaces.
If you have them correctly implemented any updates would be reflected automatically at the UI with no need of you to take care of it.
All the best,

I have implemented it like this. Can you please check if i am missing something.
public class SalesOrderViewModel : INotifyPropertyChanged
{
//Supplies the collection of Products that the Mainpage.ProductList binds to
public ObservableCollection<
SalesOrder
> Orders { get; set; }
private SalesOrder _selectedOrder;
public SalesOrder SelectedOrder
{
get { return _selectedOrder; }
set
{
_selectedOrder = value;
NotifyPropertyChanged("SelectedOrder");
}
}
public event PropertyChangedEventHandler PropertyChanged;
/// <
summary
>
/// NotifyPropertyChanged will raise the PropertyChanged event passing the
/// source property's name that is being updated.
/// </
summary
>
/// <
param
name
=
"propertyName"
></
param
>
public void NotifyPropertyChanged(String propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public SalesOrderViewModel()
{
Orders = new ObservableCollection<
SalesOrder
>();
SelectedOrder = null;
}
}
It will be a great help.
