Gets the number of records that the ListView control displays on the design surface.
Assembly: System.Web.Extensions.Design (in System.Web.Extensions.Design.dll)
The property always returns 21. This causes 21 records to be displayed in the design surface for the ListView control. An exception is if there is a DataPager control inside the ListView.LayoutTemplate template and the DataPager.PageSize property is set to a value less than 21. In that case, the number of records to display is the value of the DataPager.PageSize property. The maximum number of records that the ListView control will display on the designer surface is 21 records.
