set VisualElement to textblock inside longlistselector

[brandon]

I'm currently using a longlistselector to update a live tile using LiveTileHelper.  but i'm adding a checkbox in my longlistselector and i do not want that showing up on my tile.  i tried referencing the textblock inside the longlist but that's not working.  is it possible to set the VisualElement to a textblock inside  a longlistselector? or do i need to come up with another method?

thanks

i ended up using multiple longlistselectors....seems to work fine.

Hi,

Thank you for your question.

It is possible to get a TextBlock which is part of the LongListSelector by using our ElementTreeHelper. However, since the TextBlock is part of the ItemTemplate of LongListSelector, you have one TextBlock for each item. If I understand correctly, you want to use all TextBlock-s which are inside the LongListSelector for your tile which is not possible. If this is not the case and you want just one specific TextBlock, here's how you can get it:

TextBlock t = ElementTreeHelper.FindVisualDescendant<TextBlock>(lstTask, (descendant) =>
    {
        if (!(descendant is TextBlock))
        {
            return false;
        }
        if(((TextBlock)descendant).Text.StartsWith("1"))
        {
            return false;
        }
        return true;
    });

This call gets the first TextBlock whose Text doesn't start with "1" as an example. If you just need the first TextBlock, you can skip the predicate and use the one parameter overload:

TextBlock t = ElementTreeHelper.FindVisualDescendant<TextBlock>(lstTask)

I hope this information helps.
