# Preserve Selected Content

The TabControl comes with a built-in memory optimization where only the content of the selected tab is loaded in the visual tree.

Selecting a new tab loads its content and the content of the previous selection is unloaded. To disable this behavior and keep the content of the previously selected tab, set the `IsContentPreserved` property of `RadTabControl` to `true`.

```XAML
<telerik:RadTabControl IsContentPreserved="True" />
```
