FilterDescriptors with multiple OR filters

[Rodrigo]

Can I use FilterDescriptors with OR options?
Can you help me?

                this.FilterDescriptors.Add(new Telerik.Maui.Controls.Compatibility.DataControls.ListView.ListViewDelegateFilterDescriptor()
                {
                    Filter = new Func<object, bool>(
                        (item) => ((ListaTechnical)item).TagLogic.Contains(searchText) || 
                                  ((ListaTechnical)item).Equipment.Contains(searchText) ||
                                  ((ListaTechnical)item).Conjunto.Contains(searchText) ||
                                  ((ListaTechnical)item).Issues.Contains(searchText) ||
                                  )
                });

Regards,

Rodrigo.

Hi Rodrigo,

You can filter the ListView data by adding a filter descriptor to the filter descriptors collection. Still the scenario you shared cannot be achieved as in this case you filter the data by 4 properties, but the first one will be with highest priority. You can test on your side and will see that the collection will be filtered by TagLogic property. This is how the built-in filter descriptor is designed and implemented.

Suggestion:

For your scenario I can suggest you directly work with the collection bound to the ListView, not with the FilterDescriptor. For example you can filter the data by using a LINQ query based on your custom case.
