Hi,

Am looking for some help with searching the list of records by clicking the alphabet on the top or at the bottom of the application.

I am already listing the records but since the list is huge, i would like to select the record based on the alphabet select as it will be difficult to click next for next 20 pages to get to what I want.

Any help appreciated!!!!

Thanks

推荐答案

最简单的方法是使用CollectionView过滤数据.基本上，在WPF中，所有集合都公开一个可以通过以下方式访问的集合视图:

The easiest way to do this is to use a CollectionView to filter the data on. Basically, all collections, in WPF, expose a collection view which you can get access to like this:

CollectionView view = (CollectionView)CollectionViewSource.GetDefaultView(DataContext);

像这样过滤数据:

view.Filter = new Predicate<object>(HasLetter);
// Other commands

public book HasLetter(object o)
{
  ItemCollectionType t = o as ItemCollectionType;
  if (t == null) return false;
  return t.Name.StartsWith("F");
}
