Slow switching between tabs

[Hadrien]

Hi,

I've a RadTabControl with some RadTabItem and one of them contains a RadGridView with a lot of content (I bind an ObservableCollection).
When I switch from any tab to this one it always takes some time (a few seconds) so it seems that in some how the gridview is loaded again.

Since this list is static, are there a way to improve the performance?

Hello Hadrien,

By default the RadTabControl keeps the state of the currently selected RadTabItem, only. After changing the selection the content of the last active tab is unloaded in order to load the content of the newly selected tab. However, in your case you can try setting the IsContentPreserved property of the RadTabControl to True. By doing this you will force the RadTabControl to keep the content of its items even when they are not selected. For more information you can read this article.

Please give this approach a try and let us know if you have any other questions.

All the best,
