Unable to set property value from Session Object in a Custom WPF Dialog

hiho, i had same issue. AFAIK you have to add your public property to MSI in Installer. If you use simple ManagedProject
add it like project.AddProperty(new Property("MODE","Empty")), should work. But for BA Installer you have to add it as well for MsiPackage. Unlikwise, MSI want always all properties denified before, only then you can assign value to it at runtime.

I am already doing that :

morning, hm, strange. You can try , just for example, in CA and add it in session["MODE"] = "Whatever". See ouput in beforeinstall event - first option.
second option - Create ManagedAction CA , when.before, check.ignore, Condition.NotInstalled, Step.InstallSequence. Add also MessageBox with session["MODE"] in CA. If messagebox appears with your assign value, something wrong in your Installer.

you can also try add in project defaultdefferedproperties = ",MODE".

following code i used long time ago, for me it works.

new ManagedAction(CustomActions.SetProperty, Return.ignore, When.Before, Step.InstallFinalize, Condition.NOT_Installed)
            {
                UsesProperties = "MYPROPERTY"
            },

custom action should looks following

[CustomAction]
   public static ActionResult SetProperty(Session session)
   {
       // Get the value from the session
       string radioButtonValue = session["MYPROPERTY"];

       // Log the value for debugging purposes
       session.Log("Radio button value: {0}", radioButtonValue);

       // Based on the radio button value, set the property
       if (radioButtonValue == "Whatever1")
       {
           session["MYPROPERTY"] = "Whatever1";
       }
       else if (radioButtonValue == "Whatever2")
       {
           session["MYPROPERTY"] = "Whatever2";
       }
       else
       {
           // Handle unexpected values if necessary
           session["MYPROPERTY"] = "Unknown";
       }

       return ActionResult.Success;
   }
