Filter ObservableCollection binded to RadGridView

[Sivakumar]

Hi,
  
<telerik:RadGridView x:Name="radGridView" ShowGroupPanel="False" AutoGenerateColumns="False" ItemsSource="{Binding DataList}">
.....

</telerik:RadGridView>

ViewModel
----------

        private ObservableCollection<ClientDataRealizationModel> _dataList
        public ObservableCollection<ClientDataRealizationModel> DataList
        {
            get { return _dataList}
            set { _dataList= value; OnPropertyChanged("DataList"); }
        }

        private void OnFilter(string year)
        {
          var list = _dataList.Where(x => x.Year == year).Select(x => x);
           _dataList= new ObservableCollection<DataModel>(list);
        }

The filtered data is not showing. Should we refresh the grid ? Can anyone help me out to solve this issue.

Hi,
  I solved using this way..

 private void OnFilter(string year)
        {
          var list = _dataList.Where(x => x.Year == year).Select(x => x);
           _dataList= new ObservableCollection<DataModel>(list);

            _dataList.Clear();
            foreach (var item in list)
            {
                _dataList.Add(item);
            }
        }

Is there any way to filter the Grid without using the above way ? Bcoz i'm using backup list . How to get rid of this ?

Hi,

The ItemsSource of the GridView will be updated once a CollectionChanged event of the bound source collection is raised.
