I have a situation where if there is a single TAB in the TAB Control I do not want the Header Row section with the tabs to show, however if there are more than 1 then I do. The tabs are dynamically created at runtime.

How can I hide the tab header?

TabHeader.Visibility = tabControl.Items.Count > 1 ? Visibility.Visible : Visibilty.Collapsed;

Found that the Tab.Visibility does in fact do this and does not hide the whole tab just the tab header. Need to iteration through all tabs and set the Visibility as Collapsed.

Hi Trevor,

The fastest way is to collapse it using the VisualTreeHelper class. For example if you have a method that removes TabItems (ex. RemoveTabItem()) it might look like the following:

private void RemoveTab(RadTabItem tabItemToRemove)
{
    // Remove the tab item
    this.tabControl1.Items.Remove(tabItemToRemove);
     
    if(this.tabControl1.Items.Count == 1)
    {
        Dispatcher.BeginInvoke(() =>
        {
            var root = VisualTreeHelper.GetChild(this.tabControl1, 0) as FrameworkElement;
            var headerElement = root.FindName("HeaderDockedElement") as UIElement;
            headerElement.Visibility = System.Windows.Visibility.Collapsed;
        });
    }
}

Give it a try and let me know if it helps.

Thanks, it wasn't apparent that the visibility property on the tab only controlled the header. Much easier than retemplating the control or modifying through the visual tree. Although the VisualTreeHelper approach might be useful in some cases.
