Data Validation Lost on Switch Tabs


Product Version 2019.2.510
Product RadTabControl for WPF


The red validation border is lost when switching tabs in RadTabControl or LayoutControlTabGroup.


To resolve this, wrap the content of the corresponding tab item (RadTabItem or LayoutControlTabGroupItem) in an AdornerDecorator element.

<telerik:RadTabItem Header="Tab 1"> 
        <TextBox />
