- Handle a particular Action method on the Controller side and save the related data/message via a custom ViewData key.
- Handle the GridViewSettings.CustomJSProperties event in the GridView's PartialView and check if a custom ViewData key exists. If so, store it as a custom JS Property.
- Handle the client-side ASPxClientGridView.EndCallback event and check if a custom JS Property exists. If so, visualize its value in the required manner and remove it.

Added By: Vladimir (DevExpress Support) at: 4/21/2015 9:44:44 AMHello Venu,
This namespace is implemented in the HomeController.cs file. You can change a currently displayed file to see it. Alternatively, you can download the entire example, run it in our Example Runner and see its code.
settings.ClientSideEvents.EndCallback = "OnEndCallback"; where is this method implemented. Does this have to be in the client side java script.
Also can we access in the view razor template ViewData[HomeController.EditResultKey].ToString()
Please advise
