DxListBox<TData, TValue>.SelectedItemsChanged Event

Fires after the selection changes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v22.1.dll


public Action<IEnumerable<TData>> SelectedItemsChanged { get; set; }


Type Description

A collection of selected items.


The SelectedItemsChanged event fires each time the selection changes.

We recommend that you use the SelectedItemsChanged event to access selected items’ data source objects when the following two conditions are met:

<DxListBox Data="@Staff.DataSource"
           SelectedItemsChanged="@((IEnumerable<Person> values) => SelectedItemsChanged(values))">


@code {
    string msg;

    IEnumerable<int> Values { get; set; } = Staff.DataSource.Take(12).Select(t => t.Id);

    void SelectedItemsChanged(IEnumerable<Person> values) {
      @* Only one item is present in the collection for single selection List Box *@
      msg = values.First().FirstName + " " + values.First().LastName + " is selected";

Event usage example

In all other cases, when you need to only get the value of the selected items, use the ValuesChanged event instead of SelectedItemsChanged.
