Hi Martin,

Thank you for reaching out to us. Based on the information you shared, we have checked the reported issue. However, we were unable to replicate the problem on our end. In our testing, we set the `IsVisible` property to `False` for the layout containing the SegmentedControl, and it worked as expected on the Windows platform.

To assist you further, we have attached the tested sample for your reference. Please review the sample and let us know if you're still experiencing the issue. If not, we kindly request that you modify our sample to replicate the issue in your scenario and provide the modified sample for further investigation.

Alternatively, if modifying our sample is not feasible, please share the sample in which you originally encountered this issue. This will enable us to analyze the problem more effectively and provide a suitable solution.

Regards,

Vidyalakshmi M.

Thanks for that. The problem happens when I add Padding="0" to the SfSegmentedControl as below.

Hi Martin,

Regarding the issue “Crash in the WinUI
platform occurs if the SfSegmentedControl with padding set to ’0’ is in a layout that has IsVisible set to "False"

We have found and fixed the reported scenario from our end. We will include the issue fix in our upcoming weekly NuGet release scheduled for May 28, 2024. We appreciate your patience until then.

Hi Martin,

Regarding the issue “Crash in the WinUI
platform occurs if the SfSegmentedControl with padding set to ’0’ is in a layout that has IsVisible set to "False"

We have fixed the reported issue and included the issue fix in our latest weekly NuGet release update version 25.2.6, which is available for download at nuget.org

Root cause: The crash occurs when the layout containing the SegmentedControl is hidden (`IsVisible` set to `false`) and the padding for the SegmentedControl is set to `0`. This combination results in negative bounds for the SegmentedControl, leading to the crash.

We thank you for your support and appreciate your patience in waiting for this update. Please get in touch with us if you require any further assistance.
