Hi,

I've a non-editable UXMultipleSelectionComboBox with multiple columns enabled, but CheckAll box stop working after WebUIStudio2012 SP1 intallation. before SP1 the controls was working great.

The issue is that when the user clicks on CheckAll box the checked items are not displayed in the combobox.

Here is my xaml:

<Intersoft:UXMultipleSelectionComboBox SearchResult="{Binding FilteredLocations}"
                                       Style="{StaticResource MultipleSelectionBoxStyle}" 
				       CheckBoxHeaderVisibility="Visible"         
                                       AutoShowResultBox="False" 
                                       ScrollViewer.HorizontalScrollBarVisibility="Auto"                                             DisplayMemberPath="value"           
                                       SelectedValuePath="id" IsEditable="False">
          <Intersoft:UXMultipleSelectionComboBox.Columns>                            
                 <Intersoft:UXDataComboBoxTextColumn Header="All Locations"
						     Binding="{Binding value}"/>
          </Intersoft:UXMultipleSelectionComboBox.Columns>
</Intersoft:UXMultipleSelectionComboBox>

I attached two images showing how the application looks with SP1 and without SP1
