  • Demo Configurator

This example demonstrates how the RenderSelectedPageOnly property of RadMultiPage can significantly improve the performance of your application, when a large amount of data and HTML is loaded in each PageView.

If you set the RenderSelectedPageOnly property to true, only the content of the currently selected PageView will be loaded on the page. When another tab is selected, RadMultiPage will make a request to the server in order to load the content of the newly selected PageView.

The checkbox in the demo configurator allows you to enable and disable the RenderSelectedPageOnly functionality and observe the performance gains it brings for your app.
