Hello Pramod,

If I understand what you're trying to say correctly, you're looking to dynamically add or remove TabViewItems at runtime? This can be done by adding or removing items from the TabView's Items property.

Here's an example:

<telerikPrimitives:RadTabView x:Name="tabView"/>

tabView.Items.Add(new TabViewItem {HeaderText = "Added Tab"});

If you're asking if there is an MVVM type of property, like "ItemsSource", that is not supported at this time. You can submit a feature request here in the Feedback Portal.

In the meantime, if you do have an ObservableCollection that you'd like to keep in sync with the TabView, you can hook into the CollectionChanged event and update the TabView there.

For example:

private ObservableCollection<TabViewItem> MyTabsSource { get; set; } = new ObservableCollection<TabViewItem>();

public MyPage()
{
    InitializeComponent();

    MyTabsSource.CollectionChanged += MyTabsSource_CollectionChanged;
}

private void MyTabsSource_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
    if (e.NewItems != null && e.NewItems.Count > 0)
    {
        foreach (var item in e.NewItems)
        {
            tabView.Items.Add(item as TabViewItem);
        }
    }

    if (e.OldItems != null && e.OldItems.Count > 0)
    {
        foreach (var item in e.OldItems)
        {
            tabView.Items.Remove(item as TabViewItem);
        }
    }
}

If you have any difficulty using TabView Items.Add or Items.Remove, open a support ticket here and attach your code so that we can investigate further.
