If XAML markup has <.Resources> tag, then how to put it into <FrameworkElement.Resources> tag when RadTileView is bind to a collection of objects?

Hello. First, I apologize for the fact that I can seem somewhat intrusive. I want to use RadTileView for real-time charts displaying. For example, if I need the folowing RadCartesianChart (please see 'SensorsSignals.PNG' file attached and XAML markup below)

<telerik:RadCartesianChart x:Name="chart1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" EmptyContent="{Binding ChartEmptyContent}">
   <!--Turn scrollbar visualization off-->
   <telerik:RadCartesianChart.Resources>
      <Style TargetType="telerik:PanZoomBar">
         <Setter Property="Visibility" Value="Collapsed"/>
       </Style>
   </telerik:RadCartesianChart.Resources>
   <!--X axis-->
   <telerik:RadCartesianChart.HorizontalAxis>
      <telerik:CategoricalAxis LabelInterval="6"/>
   </telerik:RadCartesianChart.HorizontalAxis>
   <!--Y axis-->
   <telerik:RadCartesianChart.VerticalAxis>
     <telerik:LinearAxis Minimum="-128" Maximum="127" MajorStep="8" />
   </telerik:RadCartesianChart.VerticalAxis>
   <!--Chart curve itself-->
   <telerik:SplineSeries CategoryBinding="Item1" ValueBinding="Item2" ItemsSource="{Binding SensorData}" Style="{StaticResource SplineSeriesStyle}"/>
   <!--Layout grid-->
   <telerik:RadCartesianChart.Grid>
     <telerik:CartesianChartGrid MajorLinesVisibility="XY" StripLinesVisibility="XY" IsTabStop="False">
        <telerik:CartesianChartGrid.YStripeBrushes>
           <SolidColorBrush Color="#FFD7D7D7" Opacity="0.3" />
           <SolidColorBrush Color="Transparent" />
        </telerik:CartesianChartGrid.YStripeBrushes>
        <telerik:CartesianChartGrid.XStripeBrushes>
           <SolidColorBrush Color="#FFD7D7D7" Opacity="0.3" />
           <SolidColorBrush Color="Transparent" />
        </telerik:CartesianChartGrid.XStripeBrushes>
     </telerik:CartesianChartGrid>
   </telerik:RadCartesianChart.Grid>
   <!--Behaviors of the chart-->
   <telerik:RadCartesianChart.Behaviors>
     <telerik:ChartPanAndZoomBehavior DragMode="Pan" ZoomMode="Both" PanMode="Both"/>
   </telerik:RadCartesianChart.Behaviors>
</telerik:RadCartesianChart>

According to your 'DataBinding_WPF' program example and 'Data Binding' paper in http://docs.telerik.com/devtools/wpf/controls/radtileview/populating-with-data/populating-binding-to-collection I do the folowing steps.

1) In the View I write such markup:

<UserControl x:Class="UltrasonicSensors.Views.UltrasonicSensorsView"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             xmlns:prism="http://prismlibrary.com/"            
             prism:ViewModelLocator.AutoWireViewModel="True">
 
    <FrameworkElement.Resources>
        <!--Curve thickness and color style-->
        <Style x:Key="SplineSeriesStyle" TargetType="telerik:SplineSeries" BasedOn="{StaticResource SplineSeriesStyle}">
            <Setter Property="Stroke" Value="RoyalBlue"/>
            <Setter Property="StrokeThickness" Value="3"/>
        </Style>
        <DataTemplate x:Key="ItemTemplate">
            <TextBlock Text="{Binding ChartCaption}" />
        </DataTemplate>
        <!--Template of sensor signal chart-->
        <DataTemplate x:Key="ContentTemplate">
            <telerik:RadCartesianChart x:Name="chart1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" EmptyContent="{Binding ChartEmptyContent}">
                <!--Turn scrollbars off-->
                <telerik:RadCartesianChart.Resources>
                    <Style TargetType="telerik:PanZoomBar">
                        <Setter Property="Visibility" Value="Collapsed"/>
                    </Style>
                </telerik:RadCartesianChart.Resources>
                <!--X axis-->
                <telerik:RadCartesianChart.HorizontalAxis>
                    <telerik:CategoricalAxis LabelInterval="6"/>
                </telerik:RadCartesianChart.HorizontalAxis>
                <!--Y axis-->
                <telerik:RadCartesianChart.VerticalAxis>
                    <telerik:LinearAxis Minimum="-128" Maximum="127" MajorStep="8" />
                </telerik:RadCartesianChart.VerticalAxis>
                <!--Chart curve itself-->
                <telerik:SplineSeries CategoryBinding="Item1" ValueBinding="Item2" ItemsSource="{Binding SensorData}" Style="{StaticResource SplineSeriesStyle}"/>
                <!--Layout grid-->
                <telerik:RadCartesianChart.Grid>
                    <telerik:CartesianChartGrid MajorLinesVisibility="XY" StripLinesVisibility="XY" IsTabStop="False">

                            <SolidColorBrush Color="#FFD7D7D7" Opacity="0.3" />
                            <SolidColorBrush Color="Transparent" />
                        </telerik:CartesianChartGrid.XStripeBrushes>
                    </telerik:CartesianChartGrid>
                </telerik:RadCartesianChart.Grid>
                <!--Behaviors-->
                <telerik:RadCartesianChart.Behaviors>
                    <telerik:ChartPanAndZoomBehavior DragMode="Pan" ZoomMode="Both" PanMode="Both"/>
                </telerik:RadCartesianChart.Behaviors>
            </telerik:RadCartesianChart>
        </DataTemplate>
    </FrameworkElement.Resources>
 
    <Grid>
        <!--Sensors signals charts:-->
        <telerik:RadTileView x:Name="xTileView" Grid.Row="0" Grid.Column="0" PreservePositionWhenMaximized="True" MinimizedColumnWidth="150"
                             ItemTemplate="{StaticResource ItemTemplate}"
                             ContentTemplate="{StaticResource ContentTemplate}"
                             ItemsSource="{Binding SensorSignalCharts}">
        </telerik:RadTileView>
    </Grid>
</UserControl>

In the ViewModel I write something similar to the following code in C# (note!!! this code here for STUBS but not for real ultrasonic signals!!!):

All works OK here. BUT. If I need to locate inside the block of

<FrameworkElement.Resources>
  . . . . . . . . . . . . . . . . . .
</FrameworkElement.Resources>

a XAML markup which contains <UserControl.Resources>...</UserControl.Resources> blocks and <i:Interaction.Triggers>...</i:Interaction.Triggers> blocks then how WPF will behave itself in this case? Will she allow such markup or not? As far as I know, it's impossible to place one <.Resource> tag inside another <.Resource> tag. So, what I can do in this case? Below is XAML markup which I need to locate inside <FrameworkElement.Resource></FrameworkElement.Resource> tag. For clarity, I show it inside <UserControl></UserControl> tag as I've done it in the application.

If you'd like you can see gas velocity bar chart in 'GasVelocityBarChart.PNG' file attached. And you can see gas velocity spline chart in 'GasVelocitySplineChart.PNG' file attached.

So, I'm very interested in the following thing: How to put the content (that is inside the <UserControl></UserControl> tag in the figure above) into <FrameworkElement.Resources></FrameworkElement.Resources> tag? After all, this inserted content itself has in its composition the <UserControl.Resources>...</UserControl.Resources> and <i:Interaction.Triggers>...</i:Interaction.Triggers> tags. Please help me understand this. I will be very grateful to you for your help because I really appreciate your help.

Hello Yaroslav,

I am not sure that I understand your question. Can you send me an isolated example with very basic XAML that shows what is the tags structure that concerns you? 

About nesting Resources, well this is possible. As long as the syntax is correct. Resource is a property as any others and it can be set on a child object. So, for example, if you want to define a UserControl with its Resources set in the Resources of a parent control, this is possible. Here you can find a small snippet demonstrating Resources nesting.
<Window x:Class="WpfApp7.MainWindow"
        xmlns:local="clr-namespace:WpfApp7"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <DataTemplate x:Key="template">
            <ContentControl>
                <ContentControl.Resources>
                    <Style TargetType="TextBlock">
                        <Setter Property="Foreground" Value="Red" />
                    </Style>
                </ContentControl.Resources>
                <TextBlock Text="Some text" />
            </ContentControl>
        </DataTemplate>
    </Window.Resources>
    <Grid>
        <ContentControl Content="test" ContentTemplate="{StaticResource template}"/>
    </Grid>
</Window>

I also prepared a small example based on your code. You can check it on your side and let me know if I am missing something.

Regards,
Martin

</UserControl>

The matter here is the following: in my application RadTileView control is bound to the RadObservableCollection of MeasuredParameterChartViewModel instances. Where each MeasuredParameterChartViewModel instance is View Model bound to appropriate view of real-time chart (telerik:RadCartesianChart). And from the each such view the user must have an opportunity to display my custom modal dialog (by clicking an appropriate pop-up memu item). For each real-time chart view must be its own separate such modal dialog. What should I do in this case? Please help me.

Hi Yaroslav,

An interaction trigger cannot be defined as a direct content of a DataTemplate. Instead you should be able to place it in the StackPanel like so:
<DataTemplate x:Key="ContentTemplate">
    <StackPanel>
        <i:Interaction.Triggers>
            <!--My custom interaction modal dialog-->
            <prism:InteractionRequestTrigger SourceObject="{Binding InputScalingValuesConfirmationRequest, Mode=OneWay}">
                <!-- some xaml here -->
            </prism:InteractionRequestTrigger>
        </i:Interaction.Triggers>
        <TextBlock Text="{Binding City,StringFormat='City: {0}'}"/>
        <TextBlock Text="{Binding Balance,StringFormat='Balance: {0:C0}'}"/>
        <TextBlock Text="{Binding Description,StringFormat='Decription: {0}'}" TextWrapping="Wrap"/>
    </StackPanel>
</DataTemplate>

Regards,
Martin Ivanov
