Conditional mapping of a data template in XAML

Question

I have a list of text blocks that can include urls inside, smth like:

• Build error, see here: http: // ...
• Assembly completed
• App http: // myapp / cannot be started, see more details here: http: // ...

I need to display this (endless) list in a UWP application. Given that this list can be used in several views inside the application, I made it a general template:

<ResourceDictionary>
  <ControlTemplate x:Key="ListItemTemplate" TargetType="ItemsControl">
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="50"/>
        <ColumnDefinition Width="*"/>
      </Grid.ColumnDefinitions>
      <Image Grid.Column="0" Source="{Binding image_url}"/>
      <TextBlock Grid.Column="1" Text="{Binding status}"/>
    </Grid>
  </ControlTemplate>
</ResourceDictionary>

In this template, links are treated as plain text (which is expected). As far as I understand, in order to make links work, I need to wrap them in a tag <HyperLink>, but I can’t do this in the template, because I don’t know where exactly the links will be and how many of them will be displayed.

renderer, (<TextBlock>) , ?

:

<ResourceDictionary xmlns:resources="using:NamespaceWithTextBlockExt">
  <ControlTemplate x:Key="ListItemTemplate" TargetType="ItemsControl">
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="50"/>
        <ColumnDefinition Width="*"/>
      </Grid.ColumnDefinitions>
      <Image Grid.Column="0" Source="{Binding image_url}"/>
      <TextBlock Grid.Column="1" resources:TextBlockExt.XAMLText="{Binding Text}"/>
    </Grid>
  </ControlTemplate>
</ResourceDictionary>

                ctl.Inlines.Clear();

                var inlines = parsedContent.Inlines.ToList();
                parsedContent.Inlines.Clear();

                //  UI elements are removed from the source collection when the new parent 
                //  acquires them, so pass in a copy of the collection to iterate over.
