Controlling visibility of controls for a layer in the TOC

PaulHuppé

Hi,

I have the following template for layers in the TOC:

                <esri:Legend.LayerTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <!--Busy indicator-->
                            <ContentControl ContentTemplate="{StaticResource BusyIndicatorTemplate}"
           Visibility="{Binding BusyIndicatorVisibility}"/>
                            <CheckBox
                                ToolTipService.ToolTip="{Binding localizationResources.strShowlayer}"
                 IsChecked="{Binding IsEnabled, Mode=TwoWay}"
                 IsEnabled="{Binding IsInScaleRange}" >
                            </CheckBox>
                            <Image x:Name="imgZoomTo" Source="/MIB.Map.Presentation;component/Images/zoom.png"
                                   DataContext="{Binding ElementName=Toc,Path=ViewModel}"
                                   ToolTipService.ToolTip="Zoom"
                                   Tag="{Binding Content, ElementName=lblLayerName}"
                                   Cursor="Hand">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="MouseLeftButtonDown">
                                        <i:InvokeCommandAction Command="{Binding ZoomToCommand}"
                                                               CommandParameter="{Binding ElementName=imgZoomTo}" />
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>
                            </Image>
                            <RadioButton x:Name="rbLayer"
                                        DataContext="{Binding ElementName=Toc,Path=ViewModel}"
                                        IsChecked="False" 
                                        GroupName="grpSelectedLayer"
                                        Tag="{Binding Content, ElementName=lblLayerName}"
                                        ToolTipService.ToolTip="{Binding localizationResources.strSelectLayer}"
                                        Content="" >
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Checked">
                                        <i:InvokeCommandAction Command="{Binding RadioButtonCheckedCommand}"
                                                               CommandParameter="{Binding ElementName=rbLayer}" />
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>
                            </RadioButton>
                            <sdk:Label x:Name="lblLayerName"
                                       Content="{Binding Label}">
                                <ToolTipService.ToolTip>
                                    <StackPanel MaxWidth="400">
                                        <TextBlock FontWeight="Bold" Text="{Binding Layer.ID}" TextWrapping="Wrap" />
                                        <TextBlock FontWeight="Bold" Text="{Binding Label}" TextWrapping="Wrap" />
                                        <TextBlock Text="{Binding Description}" TextWrapping="Wrap" />
                                        <TextBlock Text="{Binding MinimumResolution, StringFormat='Minimum Resolution : {0:F6}'}" />
                                        <TextBlock Text="{Binding MaximumResolution, StringFormat='Maximum Resolution : {0:F6}'}" />
                                    </StackPanel>
                                </ToolTipService.ToolTip>
                            </sdk:Label>
                        </StackPanel>
                    </DataTemplate>
                </esri:Legend.LayerTemplate>

In this template, there is a RadioButton control called "rbLayer".  In code-behind, I would like to control the visibility of that control.  My question is: how do I get a hold of that control so that I can change its visibility?

Thanks,
Paul

One way that I use for certain things is to set the Visibility="{Binding Tag}" for the radio button and change the layers tag to xyz.Tag = Visibility.Collapsed or Visibility.Visible in the Code Behind.
