Manual filtering

[THOMAS]

Hello,

I want to set a filter in a GridView on loading. After adding the filter, the data is reduced correctly, but the filter symbol don't change and i can't remove the filter.

Thanks!

example code:

public MainPage()
{
    InitializeComponent();
    radGridView.DataLoaded += (s, e) =>
                                  {
                                      if (!radGridView.FilterDescriptors.Any())
                                      {
                                          CompositeFilterDescriptor newFilter = new CompositeFilterDescriptor();

                                          newFilter.FilterDescriptors.Add(
                                              new Telerik.Windows.Data.FilterDescriptor(
                                                  radGridView.Columns[0].UniqueName
                                                  , FilterOperator.Contains
                                                  , "a"));
                                          radGridView.FilterDescriptors.Add(newFilter);
                                      }
                                  };
    radGridView.ItemsSource = new List<String> {"a", "b", "c"};

}

Hello,

 You can use ColumnFilterDescriptor to achieve your goal.
