In XAML (Silverlight), how do I edit anything but the first tab in the VS Designer? All I can see is the first tab, and I don't know how to set which one is selected so that I can see the content of all tabs. Thanks!
I don't know if there is a way to do this. What you could do is set the SelectedIndex property on your TabControl to be the tab you want to visualize and then delete this property when you're done.
<controls:TabControl SelectedIndex="1">
<controls:TabItem Header="Hello">
<controls:TabItem.Content>
<StackPanel Width="400" Height="300">
<TextBlock Text="Content" />
<TextBlock Text="Content" />
<TextBlock Text="Content" />
<TextBlock Text="Content" />
</StackPanel>
</controls:TabItem.Content>
</controls:TabItem>
<controls:TabItem Header="Hello 2">
<controls:TabItem.Content>
<StackPanel Width="400"
Height="300">
<TextBlock Text="Content 2" />
<TextBlock Text="Content 2" />
<TextBlock Text="Content 2" />
<TextBlock Text="Content 2" />
</StackPanel>
</controls:TabItem.Content>
</controls:TabItem>
</controls:TabControl>
