public event SingleChoiceActionExecuteEventHandler Execute

Event Data

The Execute event's data class is SingleChoiceActionExecuteEventArgs. The following properties provide information specific to this event:

Property Description
Action Provides access to the Action being executed. Inherited from ActionBaseEventArgs.
CurrentObject Provides access to the current object represented by the currently displayed View. Inherited from SimpleActionExecuteEventArgs.
SelectedChoiceActionItem Provides access to a Single Choice Action’s selected item.
SelectedObjects Provides access to the objects selected in the currently invoked View. Inherited from SimpleActionExecuteEventArgs.
ShowViewParameters Provides access to the ShowViewParameters object, specifying a View, displayed after executing the current Action. Inherited from ActionBaseEventArgs.


Handle this event to execute custom code when an end-user clicks an item located in the current Single Choice Action’s item list (see ChoiceActionBase.Items). To access this item, use the handler’s SingleChoiceActionExecuteEventArgs.SelectedChoiceActionItem parameter. If you need an additional View to be displayed after executing the Action, use the ActionBaseEventArgs.ShowViewParameters parameter to specify this View and its settings.

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;

namespace YourSolution.Module.Controllers;

public class CustomBlazorController : ViewController {
    public CustomBlazorController() {
        var mySingleChoiceAction1 = new SingleChoiceAction(this, "MySingleChoiceAction", null);
        mySingleChoiceAction1.Items.Add(new ChoiceActionItem("Caption1", "Test1"));
        mySingleChoiceAction1.Items.Add(new ChoiceActionItem("Caption2", "Test2"));
        mySingleChoiceAction1.Execute += MySingleChoiceAction1_Execute;

    private void MySingleChoiceAction1_Execute(object sender, SingleChoiceActionExecuteEventArgs e) {
        var selectedValue = e.SelectedChoiceActionItem.Data.ToString();
        switch(selectedValue) {
            case "Test1":
                //your code
            case "Test2":
