# AJAX updates

**RadSlidingPane**, **RadPane,** and **RadSplitBar** controls can not be updated directly with an **Ajax Manager** control.

When you want to update the content of a **RadPane** (or **RadSlidingPane**) control, just add an **asp:Panel** control (or any other container control that runs on the server) inside the pane and update the panel instead the **RadPane** (or **RadSlidingPane**).

When you want to change the **RadSlidingPane**, **RadPane** or **RadSplitBar** properties, you can do it with the [client-side API](https://www.telerik.com/products/aspnet-ajax/documentation/controls/splitter/client-side-programming/overview) or you can update the whole **Splitter** or **RadSlidingZone** with the **Ajax Manager** control or with an **Ajax Panel** control.
