Blazor - Changes in GridListEditor's API

What Changed

We removed the following GridListEditor properties:

• ShowSelectionColumn
• ShowAutoFilterRow
• IsGroupPanelVisible
  You can find their equivalents in the Application Model.

We also replaced the SetSelectedObjectsKeys(IEnumerable selectedObjectsKeys) method with SetSelectedObjects(IEnumerable objectsToSelect).

Reasons for Change

These APIs were designed for internal purposes.

Impact on Existing Apps

If you use these APIs, you will get a compilation error. To address this error, do the following:

1. Use the ShowSelectionColumn, ShowAutoFilterRow, and IsGroupPanelVisible property equivalents from the Application Model:

   • IModelListViewBlazor.ShowSelectionColumn
   • IModelListViewShowAutoFilterRow.ShowAutoFilterRow
   • IModelListView.IsGroupPanelVisible

2. If you used the SetSelectedObjectsKeys method, rewrite your code so that it uses the SetSelectedObjects method instead. The following code demonstrates how to do this:

C#
using System.Collections.Generic;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.Blazor.Editors.Grid;
using MainDemo.Module.BusinessObjects;

namespace MainDemo.Module.Blazor.Controllers {
    public class MyViewController : ObjectViewController<ListView, DemoTask> {
        public MyViewController() {
            SimpleAction simpleAction = new SimpleAction(this, "Select Task", DevExpress.Persistent.Base.PredefinedCategory.Edit);
            simpleAction.Execute += (s, e) => {
                DemoTask task = ObjectSpace.FirstOrDefault<DemoTask>(d => d.Subject == "1Q Travel Spend Report");
                if (task != null && View.Editor is GridListEditor listEditor) {
                    // the following line is obsolete
                    //listEditor.SetSelectedObjectsKeys(new List<DemoTask>() { ObjectSpace.GetKeyValue(task) });
                    listEditor.SetSelectedObjects(new List<DemoTask>() { task });
                }
            };
        }
    }
}
