How to create a TabControl Silverlight

Question

Look:

TabControl def:

<sdk:TabControl x:Name="tcWords">
                <sdk:TabControl.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Vertical">
                            <TextBlock Text="{Binding Letra}" />
                            <TextBlock Text="{Binding Palabra}" />
                            <TextBlock Text="{Binding Palabra}" />
                        </StackPanel>
                    </DataTemplate>
                </sdk:TabControl.ItemTemplate>
            </sdk:TabControl>

Code:

public class Termino
    {
        public string Letra { get; set; }
        public string Palabra { get; set; }
        public string Significado { get; set; }
    }

  List<Termino> arrPalabras = new List<Termino>();
            arrPalabras.Add(new Termino { Letra = "A", Palabra = "Ave", Significado = "Cualquier cosa" });
            arrPalabras.Add(new Termino { Letra = "A", Palabra = "Avion", Significado = "Cualquier cosa avion" });
            //lstItems.ItemsSource = arrPalabras;
            tcWords.ItemsSource = arrPalabras;

It throws an exception!!!

Unable to cast object of type 'Paradigma.Silverlight.DiccionarioDatos.Termino' to type System.Windows.Controls.TabItem'.

Answer 1

Your question is a bit unclear but you can't bind your class Termino directly to the ItemsSource of the TabControl as it's not derived from TabItem.

You can try changing your declaration to:

public class Termino : TabItem
{
    ....
}

I think this should work.

The documentation for TabControl.ItemsSource doesn't really help has it points to the ItemsControl page (which TabControl inherits from) so the examples are for that rather than TabControl.

Actually, thinking about it, you should be creating a list of TabItems to set to the ItemsSource of your TabControl and binding your class to the TabItem.
