How to the DetailView in a pop-up window when adding new or editing the existing object in the Nested ListView

Hi,

I have a little issue that I can not find the solution.
I have a root detail view in view mode and with CollectionsEditMode View, with all its tabs nested listviews.
- when nested listview records are selected are shown in the main window (not in popup)
- when nested listview records are selected to edit (only one) are shown in the main window (not in popup)

the first case I solved it with this code:

C#
Frame.GetController<ListViewProcessCurrentObjectController>().CustomizeShowViewParameters += _CustomizeShowViewParameters;  

private void _CustomizeShowViewParameters(object sender, CustomizeShowViewParametersEventArgs e)  
{  
        e.ShowViewParameters.TargetWindow = TargetWindow.NewModalWindow;  
}

How can I catch the edit object or new object action to show them in popup? Because that CustomizeShowViewParameters is only for this controller, right?

Thanks in advance

Hello Juan Jose,

There are two ways to accomplish this task:

1. To change this behavior in the entire application, create a custom Show View Strategy (a DevExpress.ExpressApp.Web.ShowViewStrategy's descendant) and override its ShowViewFromNestedView method as follows:

C#
protected override void ShowViewFromNestedView(ShowViewParameters parameters, ShowViewSource showViewSource) {  
    ShowDialog(parameters, showViewSource);  
}

Then, assign this Show View Strategy to the XafApplication.ShowVIewStrategy property at the applicaiton startup.
2. To change this behavior only in a certain ListView, handle the NewObjectViewController.NewObjectAction.Execute and ListViewController.EditAction.Execute events and set the e.ShowViewParameters.TargetWindow property to NewModalWindow.

Feel free to contact us if you need further assistance.
