Assembly : DevExpress.ExpressApp.v25.2.dll

public class ShowViewParameters
Public Class ShowViewParameters
The following members return ShowViewParameters objects:
Use the ShowViewParameters object to specify view settings for the View.
The following example demonstrates how to use a ShowViewParameters object in an Action’s Execute event handler. The code customizes the Accept Action:
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.SystemModule;
using MainDemo.Module.BusinessObjects;
namespace YourApplicationName.Blazor.Server.Controllers {
public class ShowViewController : ViewController {
SimpleAction showViewAction;
public ShowViewController() {
showViewAction = new SimpleAction(this, "ShowEmployeesList",
DevExpress.Persistent.Base.PredefinedCategory.Edit);
showViewAction.Execute += ShowViewAction_Execute;
}
private void ShowViewAction_Execute(object sender, SimpleActionExecuteEventArgs e) {
IObjectSpace objectSpace = Application.CreateObjectSpace(typeof(Employee));
string listViewId = Application.FindListViewId(typeof(Employee));
e.ShowViewParameters.CreatedView = Application.CreateListView(
listViewId,
Application.CreateCollectionSource(objectSpace, typeof(Employee), listViewId),
true);
e.ShowViewParameters.TargetWindow = TargetWindow.NewModalWindow;
var dlgCnt = Application.CreateController<DialogController>();
dlgCnt.Accepting += DlgCnt_Accepting;
e.ShowViewParameters.Controllers.Add(dlgCnt);
}
private void DlgCnt_Accepting(object sender, DialogControllerAcceptingEventArgs e) {
// Add your custom code here.
}
}
}
Note
XAF creates a DialogController for Pop-up Windows by default.
XafApplication.ShowViewStrategy manages Window and View visibility. This strategy may use properties of a ShowViewParameters object.
