New Post: ComboBox in CollectionControl

Hi yt2014,

You can try setting a DataTemplate for specific properties with the PropertyGrid.EditorDefinitions. In the PropertyGrid Default Editors example available in the LiveExplorer sample, define a DataTemplate for the 3 lists :

<xctk:PropertyGrid x:Name="_propertyGrid"
                         SelectedObject="{Binding}"
                         Width="450"
                         Margin="10,30,0,0">

         <xctk:PropertyGrid.EditorDefinitions>
            <xctk:EditorTemplateDefinition TargetProperties="ListOfInt32">
               <xctk:EditorTemplateDefinition.EditingTemplate>
                  <DataTemplate>
                     <ComboBox ItemsSource="{Binding Value}"/>
                  </DataTemplate>
               </xctk:EditorTemplateDefinition.EditingTemplate>
            </xctk:EditorTemplateDefinition>

            <xctk:EditorTemplateDefinition TargetProperties="ListOfPerson">
               <xctk:EditorTemplateDefinition.EditingTemplate>
                  <DataTemplate>
                     <ComboBox ItemsSource="{Binding Value}" />
                  </DataTemplate>
               </xctk:EditorTemplateDefinition.EditingTemplate>
            </xctk:EditorTemplateDefinition>

            <xctk:EditorTemplateDefinition TargetProperties="ListOfStrings">
               <xctk:EditorTemplateDefinition.EditingTemplate>
                  <DataTemplate>
                     <ComboBox ItemsSource="{Binding Value}" />
                  </DataTemplate>
               </xctk:EditorTemplateDefinition.EditingTemplate>
            </xctk:EditorTemplateDefinition>

         </xctk:PropertyGrid.EditorDefinitions>
      </xctk:PropertyGrid>

ComboBoxes will be used to display the content of the lists. For the Person's list, you can redefine the ToString method of the Person's class to make it show the name of the Persons:

 public class Person
    {
      public string Name { get; set; }

      public override string ToString()
      {
        return this.Name;
      }
    }
