Description

How can I filter the DropDownList items by multiple properties?

Solution

1. Prevent the default behavior of the filter event.
2. Use the dataSource filter method to apply the custom filtering.

Example

View Source

	<input id="customers" style="width: 100%;"/>            

    <script>
        $(document).ready(function() {
            $("#customers").kendoDropDownList({
                dataTextField: "ContactName",
                dataValueField: "CustomerID",
              	filter: "contains",
                template: `<h3>Name: #: data.ContactName #</h3>
              							<h4>ID: #: data.CustomerID #</h4>`,
                dataSource: {
                    transport: {
                        read: {
                            url: "https://demos.telerik.com/service/v2/core/Customers",
                        }
                    }
                },
              	filtering: function(ev){
                	var filterValue = ev.filter != undefined ? ev.filter.value : "";
                    ev.preventDefault();

                  this.dataSource.filter({
                    logic: "or",
                    filters: [
                      {
                        field: "ContactName",
                        operator: "contains",
                        value: filterValue
                      },
                      {
                        field: "CustomerID",
                        operator: "contains",
                        value: filterValue
                      }
                    ]
                  });
                }
            });
        });
    </script>
