using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.Blazor.Editors;
using DevExpress.Persistent.Base;
using MySolution.Module.BusinessObjects;
using System;

namespace MySolution.Module.Blazor.Controllers {
    public class MySelectController : ObjectViewController<ListView, DemoTask> {
        public MySelectController() {
            SimpleAction selectCurrentTasksAction = new SimpleAction(this, "SelectCurrentTasksAction", PredefinedCategory.View) {
                Caption = "Select Due Today Tasks",
                SelectionDependencyType = SelectionDependencyType.Independent,
                TargetViewNesting = Nesting.Root
            };
            selectCurrentTasksAction.Execute += SelectCurrentTasksAction_Execute; ;
        }

        private void SelectCurrentTasksAction_Execute(object sender, SimpleActionExecuteEventArgs e) {
            if(View.Editor is DxGridListEditor gridListEditor) {
                gridListEditor.SetSelectedObjects(
                    ObjectSpace.GetObjects<DemoTask>(
                        CriteriaOperator.FromLambda<DemoTask>(task => task.DueDate == DateTime.Today)
                    )
                );
            }
