Remarks
The RenderPartial method renders an ASP.NET user control (.ascx file) as a partial view.
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. Therefore, the partial view has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed.
