Description Anubhav Ranjan 2016-07-13 13:37:49 UTC
I believe I am experiencing a bug on UWP with Xamarin Forms. Setting LineBreakMode to TailTruncation doesn't seem to work correctly on UWP. This <http://i.imgur.com/0JaI0rv.png> is what a simple listview looks like with long text set to TailTruncation. It instantly truncates without consideration for what space it has. If you rotate the device, this<http://i.imgur.com/VjPvPIO.png> is what happens, it extends the text as far as it can and truncates, but doesn't add an ellipse.
I have a workaround with a custom renderer that sort of works:

I need to set the platform specific truncation for the control, Control.TextTrimming = Windows.UI.Xaml.TextTrimming.CharacterEllipsis;
And I need to set the minimum in GetDesiredSize, I guess this forces it do a size calculation and displays the label correctly, this <http://i.imgur.com/r68HhUT.png> is what it looks like.

But it has the same issue where if I rotate, it will truncate, but won't show the ellipse.

Comment 3 E.Z. Hart [MSFT] 2016-08-25 21:16:24 UTC
This bug is *not* a duplicate of 42559. 42559 is about wrapping text, not truncating it.

What is the progress on this? We are in need of this functionality.
Comment 5 E.Z. Hart [MSFT] 2016-10-04 19:53:37 UTC
Should be fixed in 2.3.3-pre3
