Hi
The referenced articles mention ASPxPopupControl but I have no idea how to integrate ASPxPopupControl in XAF in this scenario. Is there an example I can see for clarification? I had already browsed through most of the given articles before posting question. There is just too much information to comprehend and use for the simple option that I need ie displaying a modal popup message from code (not action).
Thanks

Hi,
Have you reviewed the help links given in the Web - Support complex dialogs on the client-side in XAF ASP.NET applications (similar to the MessageBox in Windows Forms) and Support - provide an example, illustrating how to show a dialog window in the Web ( S19008 ) threads?
In addition, I suggest you review the ASPxPopupControl documentation, Code Central examples, and demos: http://demos.devexpress.com/ASPxperienceDemos/PopupControl/ClientSide.aspx
They provide the code examples you are looking for. Let me know if I can assist you further.
Thanks,
Dennis

Hi Dennis
I have checked all of them but which particular one(s) are you recommending for my case? I have asked a specific question and would love a specific answer to my needs instead of a lot of articles which discuss all sorts of things including possible future enhancements to XAF.

Hello Yahya,
In my opinion all these help links are important. Let's start with the How to create ASPxPopupControl at runtime example for the beginning. Let me know if you experience any difficulties with this.
Thanks,

Hi Dennis
My question is not how to use web controls in a normal web app. I do it all the time. My question is how to show a dialog specifically in an XAF web app which I am not sure as a starter as to how similar it is to a normal web app. I gather from your reply that using the ASPxPopupControl is the correct strategy in your opinion. In that case my question is can you point me to some specific info on how to integrate ASPxPopupControl in XAF app keeping in mind my specific scenario?
Thanks

Yes, you are correct.

The example I suggested shows how to add a popup control to a web page. To get the web page in XAF, create a ViewController and override its OnViewControlsCreated method as follows:

C#
...  
        protected override void OnViewControlsCreated() {  
            base.OnViewControlsCreated();  
            Page page = Frame.Template as Page;  
...  

Then you can handle web page events as in regular non-XAF web application.
I hope you find this information helpful.
Thanks,
Dennis

Hi Dennis
Thanks.
My view controller code is given below at the end. Where I am stuck is how to show the dialog at will in the ObjectSpace_Committed event below. Its one thing to show the popup from a normal web page either client side or server side but how to show it from within the view controller code, as in my case, I am not sure. Some help to achieve the show of the popup from code would be appreciated.
Thanks

Hello,
The following controller worked fine in my tests:

C#
using System;  
using System.ComponentModel;  
using System.Collections.Generic;  
using System.Diagnostics;  
using System.Text;  

using DevExpress.ExpressApp;  
using DevExpress.ExpressApp.Actions;  
using DevExpress.Persistent.Base;  
using DevExpress.Web.ASPxPopupControl;  
using System.Web.UI;  
using DevExpress.ExpressApp.Web;  

namespace MainDemo.Module.Web {  
    public partial class ViewController1 : ViewController<DetailView> {  
        ASPxPopupControl popup;  
        public ViewController1() {  
            InitializeComponent();  
            RegisterActions(components);  
            TargetObjectType = typeof(MainDemo.Module.BusinessObjects.Contact);  
        }  
        protected override void OnActivated() {  
            base.OnActivated();  
            ObjectSpace.Committed += new EventHandler(ObjectSpace_Committed);  
        }  
        protected override void OnDeactivated() {  
            ObjectSpace.Committed -= new EventHandler(ObjectSpace_Committed);  
            base.OnDeactivated();  
        }  
        void ObjectSpace_Committed(object sender, EventArgs e) {  
            popup = new ASPxPopupControl();  
            popup.ID = popup.ClientInstanceName = popup.HeaderText = "popup";  
            popup.Modal = true;  
            popup.AllowDragging = true;  
            ((Control)View.Control).Controls.Add(popup);  
            WebWindow.CurrentRequestWindow.RegisterStartupScript("showPopup", "popup.Show();");  
        }  
    }  
}  

I hope you find this information helpful.
Thanks,
Dennis
