    Hello,

    I was wondering if TabView has events, for example, on tab selection? If I wanted to load contents of a tab only when it is selected, is there such a mechanism available?

    Hi Mikhail,

    Currently, the TabView does not expose such events. I have logged your requirement as a feature request in our Ideas & Feedback portal - TabView: Introduce events related to the Tab selection. I suggest you follow the item in order to receive automatic notifications for major updates. I have also added some points to your account for the suggestion.

    In the meantime, you can subscribe to the PropertyChanged event of the RadTabView to get notified when the SelectedItem is changed. For example:

    private void TabView_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
           {
               if (e.PropertyName == "SelectedItem")
               {
                   var selectedTab = this.TabView.SelectedItem as TabViewItem;
                   if (selectedTab.HeaderText == "Folder")
                   {
                       selectedTab.Content = new Label() { Text = "This is the content of the Folder tab", BackgroundColor = Color.Red };
                   }
               }
           }

    Have a great weekend.
