[sum sum]

Hi Guys,

I want to add a filter to select any rows that has id from an array, let's say [1, 5, 18]. 

How to write the property filterdescriptor?

this.CustomersGridView.FilterDescriptors.Add(new FilterDescriptor("Id", FilterOperator???

Hello sum sum,

Here is how to do it:

using System.Windows.Controls;
using Telerik.Windows.Controls;
using Telerik.Windows.Data;

namespace TicketID_255841_CompositeFilterDescriptor
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();

            int[] playerNumbers = new [] {25, 23, 8, 9};

            CompositeFilterDescriptor compositeFilter = new CompositeFilterDescriptor();
            compositeFilter.LogicalOperator = FilterCompositionLogicalOperator.Or;

            foreach (int playerNumber in playerNumbers)
            {
                FilterDescriptor numberFilter = new FilterDescriptor("Number", FilterOperator.IsEqualTo, playerNumber);
                compositeFilter.FilterDescriptors.Add(numberFilter);
            }

            this.playersGrid.FilterDescriptors.Add(compositeFilter);

            this.playersGrid.ItemsSource = Club.GetPlayers();
        }
    }
}

I have attached a sample project. I hope it helps.
