If you are working with a large amount of data, in addition to displaying your list a grouped list, you can enable a nifty feature that enables the user of your application to jump to a specific section in your list. However, you must supply the whole list before the group section index feature can be shown, since incremental loading scenario is not applicable when showing the group section index. This page discusses how you can use the feature in just a matter of overriding properties in the view section of each platform. If you wish to display the grouped list, see Displaying and Customizing Group List.

If your data contains fairly large number of groups, you may want to show the group index to allow users to easily jump to a specific group.

The C# represents the groups whose name started with number or non-alphabet.
