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. |

| ShowViewParameters | Provides access to the ShowViewParameters object, specifying a View, displayed after executing the current Action. Inherited from ActionBaseEventArgs. |
Remarks
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
break;
case "Test2":
//your code
break;
