How to add a hyperlink to a new object to a standard aspx page

Hello Paolo,

You can get a link to a DetailView with a certain object using a ViewShortcut. For example:

C#
Session session = new Session();  
session.ConnectionString = "Integrated Security=SSPI;Pooling=false;Data Source=(local);Initial Catalog=Solution1";  
ViewShortcut shortcut = new ViewShortcut("DomainObject1_DetailView", session.FindObject<DomainObject1>(null).Oid);  
string url = xafApplicationUrl + "?Shortcut" + shortcut.ToString();  

To show a DetailView with a new object, handle the XafApplication.CustomProcessShortcut event (e.g. in the YourSolutionName.Web/Global.asax.xx file or from your Controller where you have access to its "Application" property) or override the protected virtual OnCustomProcessShortcut method of your XafApplication descendant in the YourSolutionName.Web/WebApplication.cs file, as shown below:

C#
ViewShortcut result = new ViewShortcut("DomainObject1_DetailView", null);  
result["mode"] = "ExternalCall";  
HttpContext.Current.Response.Redirect(new DefaultHttpRequestManager().GetQueryString(result));  
...  
protected override void OnCustomProcessShortcut(DevExpress.ExpressApp.CustomProcessShortcutEventArgs args) {  
    base.OnCustomProcessShortcut(args);  
    if (args.Shortcut["mode"] == "ExternalCall") {  
        args.Handled = true;  
        IObjectSpace os = CreateObjectSpace();  
        IModelDetailView viewModel = (IModelDetailView)FindModelView(args.Shortcut.ViewId);  
        object obj = os.CreateObject(viewModel.ModelClass.TypeInfo.Type);  
        DetailView view = CreateDetailView(os, args.Shortcut[ViewShortcut.ViewIdParamName], true, obj);  
        view.ViewEditMode = ViewEditMode.Edit;  
        args.View = view;  
    }  
}  

If you are using the Security System with the Standard Authentication, you may also need to automatically login the user and skip the logon window. See how to do this here: How to skip the logon page and automatically authenticate a user in code (e.g. from an external link).
To show a DetailView without logging in the user, use the following solution: How to produce a web link that shows a DetailView of a certain object without authentication.

Update:
To show a DetailView with a new object, handle the XafApplication.CustomProcessShortcut event or override the XafApplication.OnCustomProcessShortcut method, as shown below:

Code
C#ViewShortcut result = new ViewShortcut("DomainObject1_DetailView", null);  
result["mode"] = "ExternalCall";  
HttpContext.Current.Response.Redirect(new DefaultHttpRequestManager().GetQueryString(result));  
...  
protected override void OnCustomProcessShortcut(DevExpress.ExpressApp.CustomProcessShortcutEventArgs args) {  
    base.OnCustomProcessShortcut(args);  
    if (args.Shortcut["mode"] == "ExternalCall") {  
        args.Handled = true;  
        IObjectSpace os = CreateObjectSpace();  
        IModelDetailView viewModel = (IModelDetailView)FindModelView(args.Shortcut.ViewId);  
        object obj = os.CreateObject(viewModel.ModelClass.TypeInfo.Type);  
        DetailView view = CreateDetailView(os, args.Shortcut[ViewShortcut.ViewIdParamName], true, obj);  
        view.ViewEditMode = ViewEditMode.Edit;  
        args.View = view;  
    }  
}
