title: Search in listbox with wpf
body: <p>i have a listview, binded with an observable collection of objects. Here the objects are "questions". I want to implement a sort of search engine. In textbox or something. But i have 3 columns. 1 of description, 1 of shortname and 1 of the type of the question. Here is the code of my listview :</p>
  
  <pre><code> &lt;ListView IsTextSearchEnabled="True"  TextSearch.TextPath="Description" ScrollViewer.CanContentScroll="True" SelectedItem="{Binding Path=SelectedQuestionDragList, UpdateSourceTrigger=PropertyChanged,Mode=OneWayToSource}" dd:DragDrop.IsDragSource="True" 
    dd:DragDrop.IsDropTarget="False"  Margin="0,34,393,333" Background="#CDC5CBC5" ScrollViewer.VerticalScrollBarVisibility="Visible"
                   dd:DragDrop.DropHandler="{Binding}" Name="listbox1" Height="155"  ItemsSource="{Binding AvailableQuestions}" SelectionChanged="listbox1_SelectionChanged"&gt;
              &lt;ListView.View&gt;
                  &lt;GridView&gt;
                      &lt;GridView.Columns&gt;
                          &lt;GridViewColumn Header="Verkorte naam" Width="Auto" DisplayMemberBinding="{Binding Path=ShortName}" /&gt;
                          &lt;GridViewColumn Header="Omschrijving" Width="Auto" DisplayMemberBinding="{Binding Path=Description}" /&gt;
                          &lt;GridViewColumn Header="Type" Width="Auto" DisplayMemberBinding="{Binding Path=Type}" /&gt;
                      &lt;/GridView.Columns&gt;
                  &lt;/GridView&gt;
              &lt;/ListView.View&gt;
          &lt;/ListView&gt;
  </code></pre>
  
  <p>I have tried already a lot of things. But i just want to keep one simple thing: a textbox ,and if you fill in there some letters, the program has to filter where this combination of letters is exists. Someone who knows a simple solution or example?</p>
  
  <p>Thanks!</p>
