Silverlight filtering data with checkboxes like pivotviewer?

I'm building an internal file portal style app in silverlight,

I need to be able to filter the files by category using checkboxes like in pivotviewer:

To display the categories im using a ItemsControl, and am currently using a hacky workaround to store the category id.. so files can be added and removed appropriaely when somethings check or unchecked:

                    <ItemsControl x:Name="categoryList" ItemsSource="{Binding}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal" Margin="2">
                                <CheckBox Checked="categoryIncluded" Unchecked="categoryExcluded" Content="{Binding ID}">
                                    <CheckBox.ContentTemplate>
                                        <DataTemplate>
                                            <!-- This is a hack, content is being used to store the id of the category -->
                                        </DataTemplate>
                                    </CheckBox.ContentTemplate>
                                </CheckBox>
                                <TextBlock Foreground="#FFC2BDBD" Text="{Binding Name}"/>
                            </StackPanel>
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>

This seems like a massive hack,

How is this normally done in silverlight?

(I'm using RIA data services by the way)

Solution

  • To avoid that hack you could create custom control that conteins chekbox + other data and id property
