Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type HtmlHelper. When you use instance method syntax to call this method, omit the first parameter. For more information, see or

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.
