WPF Filter

Terrible trouble. Predicate confusion. Following works

Method 1 : Entity Framework

See http://wp.me/p17IS4-mX

Method 2

CType(BookViewSource.View, BindingListCollectionView).CustomFilter = String.Concat(“Title LIKE ‘%”, FilterTextBox.Text, “%'”)

Method 3

Dim view As New System.Data.DataView(Me.dsBook1.Books)
view.RowFilter = String.Format(“Title LIKE ‘%{0}%'”, FilterTextBox.Text)
MainGrid.DataContext = view

then possibly with Try-Catch

Private Sub ClearFilter()
MainGrid.DataContext = BookViewSource
CType(BookViewSource.View, BindingListCollectionView).CustomFilter = Nothing
End Sub
