Remarks

The ShowViewFromCommonView method opens the specified View.

• In Single Document Interface mode, XAF displays the View in the same window.
• In Multiple Document Interface mode, XAF displays the View in a new Frame (window or tab).

The following code sample creates a controller with action that opens a new ListView in the same window (in SingleWindowSDI mode) or in a separate tab (in TabbedMDI mode).

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

namespace MySolution.Blazor.Server.Controllers;

public class CustomBlazorController : ObjectViewController<DetailView, Contact> {
    public CustomBlazorController() {
        var myAction = new SimpleAction(this, "MyBlazorAction", PredefinedCategory.Edit);
        myAction.Execute += MyAction_Execute;
    }
    private void MyAction_Execute(object sender, SimpleActionExecuteEventArgs e) {
        var objectSpace = Application.CreateObjectSpace(typeof(Contact));
        var listView = Application.CreateListView(typeof(Contact), true);
        Application.ShowViewStrategy.ShowViewFromCommonView(listView, this.Frame, (ActionBase)sender);
    }
}
