using DevExpress.Persistent.Base;
using MySolution.Module.BusinessObjects;

namespace MySolution.Module.Blazor.Controllers {
    public class MySelectController : ObjectViewController<ListView, DemoTask> {
        public MySelectController() {
            SimpleAction unselectTaskAction = new SimpleAction(this, "UnselectTaskAction", PredefinedCategory.View) {
                Caption = "Unselect a Task",
                SelectionDependencyType = SelectionDependencyType.RequireSingleObject,
                TargetViewNesting = Nesting.Root
            };
            unselectTaskAction.Execute += UnselectTaskAction_Execute; ;
        }

        private void UnselectTaskAction_Execute(object sender, SimpleActionExecuteEventArgs e) {
            if(View.Editor is DxGridListEditor gridListEditor) {
                var selectedObjects = gridListEditor.GetSelectedObjects();
                if(selectedObjects.Count == 1) {
                    gridListEditor.UnselectObject(selectedObjects[0]);
                }
            }
        }
    }
}
