Data Validation Lost on Switch Tabs
Environment

Description
The red validation border is lost when switching tabs in RadTabControl or LayoutControlTabGroup.
Solution
To resolve this, wrap the content of the corresponding tab item (RadTabItem or LayoutControlTabGroupItem) in an AdornerDecorator element.
<telerik:RadTabItem Header="Tab 1">
<AdornerDecorator>
<TextBox />
</AdornerDecorator>
</telerik:RadTabItem>
