How to Get SelectedItem as DataTemplate in Listview?-CodePudding

I have a listview Which is defined as follows:

<DataTemplate x:Name="myTemplate" x:DataType="table:myItem">
  <RichTextBlock Margin="10" IsTextSelectionEnabled="False">
    <Paragraph x:Name="txtParagraph">
      ....
    </Paragraph>
  </RichTextBlock>
</DataTemplate>

<ListView name="lst" ItemTemplate="{StaticResource myTemplate}"/>

lst.ItemSource = someData;

Now I want to get paragraph from the DataTemplate of the current item something like this:

paragraph = GetParagraphFromItem(listview.selectedItem)

How can I do this?

You could get each ListViewItem with ContainerFromItem method and then you could access item's ContentTemplateRoot property to get RichTextBlock. And Paragraph was stored in RichTextBlock's Blocks collection.

 var listviewItem = MyListView.ContainerFromItem(yourselecteditem) as ListViewItem;
 RichTextBlock rtb = listviewItem.ContentTemplateRoot as RichTextBlock;
 var txtParagraph = rtb.Blocks.Where(p => p.Name == "txtParagraph").FirstOrDefault();
