Hello there. 

This code returns negative MaxSize on 100% dpi, since it overflows int.

var dpiScaleFactor = radLabel1.RootElement.DpiScaleFactor;
var r1 = new Size(150, int.MaxValue);
var r2 = TelerikDpiHelper.ScaleSize(r1, new SizeF(1f / dpiScaleFactor.Width, 1f / dpiScaleFactor.Height));

I use that code to descale some sizes on runtime per suggestion on the forum, also I have seen similar code in Telerik sources. When control receives negative max size it becomes invisible. You may want to investigate this cases. 

I use Telerik 2018.3.1016.20 with .Net 3.5 on Server 2008 R2 SP1.

Best regards.

Hello Jeremy,

Thank you for reporting this. We will consider your feedback. 

Please note that it is not common to use Int.MaxValue for size, if you do not want to set maximum height just use 0 instead.

Should you have any other questions do not hesitate to ask.

Regards,
