New Post: Edition of CollectionControl Editors

Hi,

I have one problem with the CollectionEditor open by the PropertyGrid.
For my propertyGrid I have redefine some template like that but it's not propagated in the CollectionEditor, so how can I edit specific editor for the CollectionEditor ?

Thanks in advance if it's possible

<xctk:PropertyGrid.EditorDefinitions>
                        
       <xctk:EditorTemplateDefinition TargetProperties="{x:Type system:DateTime}">
                <xctk:EditorTemplateDefinition.EditingTemplate>
                      <DataTemplate>
                           <xctk:DateTimePicker TextAlignment="Left" Format="LongDate"            TimePickerVisibility="Collapsed" ShowButtonSpinner="False" AutoCloseCalendar="True" BorderThickness="0"/>
                        </DataTemplate>
                  </xctk:EditorTemplateDefinition.EditingTemplate>
           </xctk:EditorTemplateDefinition>

                        
</xctk:PropertyGrid.EditorDefinitions>
