Throw exception on UWP when open popup

[Itai]

Hello,

When I try to open a popup in uwp (Tried on local machine - windows 10) it throws the following exception : 

System.ArgumentException: 'Value does not fall within the expected range.'

 

The command I used: 

continuePopup.IsOpen = true;

Hi,

I have tested our Popup SDK examples and I cannot reproduce the following exception. 

We have recieved similar crash with the RadButrton and RadBorder controls on UWP but not for the RadPopup control. If you have placed inside the popup - RadBorder or RadButton  I suggest you set BorderTickness to 0 and check whetehr the issue will be solved.

If this suggestion does not solve the issue, as a next step, please open a support ticket and attach a repro project there. Also add the following information:

- versions of Xamarin and Telerik used in the project.

- versions of the Windows and Visual Studio.

Hello,

That solved the issue, but what if I want a border? Would it be fixed in the next version?

 

Thank you.

Hi,

We have an issue logged in our feedback portal regarding this exception for the RadButton control: https://feedback.telerik.com/xamarin/1402384-button-uwp-argumentexception-is-raised-when-targeting-windows-10-version-1809

and the reply in the feedback item:

"
You can fix this by setting BorderThickness to zero:

<RadButton BorderThickness="0"/>

The reason the problem arises in 1903 (SDK 18362) is because Microsoft changed the behavior of UWP controls and default values for null when it's a non nullable property type. Traditionally, you'd use "-1", but that is no longer accepted and causes an OutOfRangeException Therefore, by overriding the default -1 value with 0, you avoid the exception.

Note: this also rears it's head in other places, like RadBorder. If you see this exception again, try setting BorderThickness to 0 on those controls as well.

"

By default the value for the borderthickness is -1 and exception is raised. When you change it to 0 you avoid the exception. Indeed you can also change its value to 5, 10 or the value needed for your requirements.
