title: Autocomplete combobox vs2017 - properties
body: <p>I have a problem with combobox. I do not have properties for him. Where can I find AutoComplete properties?
  Typing also does not suggest anything to me and as I enter the whole thing, I get the error.
  I'm explaining what I mean - I have a combobox with many list records.
  I would like the combobox to open, for example, the first three letters.</p>
  
  <p>this is my code of combobox</p>
  
  <pre><code> &lt;ComboBox
              x:Name="combolista" 
              HorizontalAlignment="Left" 
              Margin="10,384,0,0"
              VerticalAlignment="Top"
              Width="491" 
              Grid.Column="1"
              SelectionChanged="ComboBox_SelectionChanged"
              ItemsSource="{Binding Wyszukanie_miast}"
              SelectedItem="{Binding WybraneMiasto}" 
              IsEditable="True" 
              TextSearch.TextPath="Miasto"&gt;
              &lt;ComboBox.ItemTemplate&gt;
                  &lt;DataTemplate&gt;
                      &lt;Grid&gt;
                          &lt;TextBlock Text="{Binding Miasto}" /&gt;
                          &lt;TextBlock Text="Województwo" Margin="70,0,0,0"/&gt;
                          &lt;TextBlock Text="{Binding Wojewodztwo}" Margin="150,0,0,0"/&gt;
                      &lt;/Grid&gt;
                  &lt;/DataTemplate&gt;
              &lt;/ComboBox.ItemTemplate&gt;
  &lt;/ComboBox&gt;
  
  </code></pre>
  
  <p>He works but I would like to enter all the possibilities in three letters</p>
