Editable Combox

Hey,

Im trying to use an combobox that is editable, the problem is that when selecting an item from the list raises the setValue in the DescriptorPropertyInfoAdapter class but when I type free text into it, the event doesnt get fired, is there an way of the event firing when changing the text.

<ComboBox Name="myComboBox" SelectedValue="{Binding Value}" ItemsSource="{Binding Source={StaticResource QueueEntityCollection}}" SelectedValuePath="ID" DisplayMemberPath="Name" IsEditable="True" >

</ComboBox>

</DataTemplate>

Thanks,

Looking at our built-in combo box-based editor, which supports typing into the text area, I see that we are binding SelectedItem rather than SelectedValue.  Could you give that a try?  If that doesn't work either then let me know and I will see if I can work something up for you.

I tried to use the SelectedItem instead SelectedValue, I get the same result unfortunately

Hello Justin,

Looks like you may also need to bind Text.  Here's my sample:

XAML (with xmlns:s="clr-namespace:System;assembly=mscorlib" and xmlns:scs="clr-namespace:System.Collections.Specialized;assembly=System"):

  <Window.Resources>
   
    <scs:StringCollection x:Key="MightyOaths">
      <s:String>Fie</s:String>
      <s:String>Zounds</s:String>
      <s:String>Ods Bodikins</s:String>
    </scs:StringCollection>
   
    <DataTemplate x:Key="EditableComboBox">
      <ComboBox ItemsSource="{StaticResource MightyOaths}" SelectedItem="{Binding Value}" IsEditable="True" Text="{Binding Value}" />
    </DataTemplate>
   
  </Window.Resources>
 
  <ms:PropertyGrid Name="pg" Margin="10">
    <ms:PropertyGrid.Editors>
      <ms:PropertyEditor PropertyName="FavouriteOath" EditorTemplate="{StaticResource EditableComboBox}" />
    </ms:PropertyGrid.Editors>
  </ms:PropertyGrid>

Data class:

  public class Baron : Observable
  {
    private string _name;

    public string Name
    {
      get { return _name; }
      set { Set(ref _name, value, "Name"); }
    }

    private string _favouriteOath;

    public string FavouriteOath
    {
      get { return _favouriteOath; }
      set { Set(ref _favouriteOath, value, "FavouriteOath"); Debug.WriteLine(value); }
    }
  }

When I type into the text area of the combo box, I see the Debug.WriteLine getting executed with the appropriate value.

Hope this helps! 

Thanks Ivan, works great
