I am using MVVM pattern in my project and used Tab Control. Tab Items have validation.
    <grid x:name="Layout Root" xmlns:x="#unknown">
        <tabcontrol bindingvalditionerror="TabControl_validtion" x:name="TabControl">
                <myusercontrol1 datacontext="{Binding}" />
                <myusercontrol2 datacontext="{Binding}" />
                <myusercontrol2 datacontext="{Binding}" />
  private void TabControl_validtion(object sender, ValidationErrorEventArgs e)
            switch (e.Action)
                case ValidationErrorEventAction.Added:
                    if (!Errors.Contains(e.Error))
                case ValidationErrorEventAction.Removed:
it's showing only errors for visible(currently opened) TabItem. And i need to show all the errors from all tabs. How can i achieve this?
