Hello Zach,

Thank you for the confirmation. I changed the status of the item to Completed. It seems the behavior was related to the XCode or .NET Maui version, as with Telerik MAUI 6.5.0/6.7.0 the issue cannot be reproduced and we didn't apply any fixes in the segmented control.

Hi Zach,

The team tested the behavior and it seems the issue no longer occurs. Could you please verify on your side? 

For example I tested on iPhone simulator 15 with iOS 17.0 and iOS 17.2 and no issue. I have used Telerik MAUI 6.6.0 and 6.7.0

I can suggest you update maui, XCode, iOS version, etc. It seems the behavior is related to some of the versions of XCode, iOS, Microsoft .NET iOS sdk, maui, etc. With Telerik 6.6.0 and 6.7.0 there isn't an issue with the segmented control. 

Looking forward to your reply.

For now you can use the following workaround - subscribe to the SegmentedControl HandlerChanged:

<telerik:RadSegmentedControl
    x:Name="segmented"
    HandlerChanged="segmented_HandlerChanged">

and inside the HandlerChanged get the native UISegmentedControl and set its selected background color, for example:

void segmented_HandlerChanged(System.Object sender, System.EventArgs e)
{
#if IOS
    if((sender as RadSegmentedControl)?.Handler?.PlatformView is UIKit.UISegmentedControl segmented)
    {
        segmented.SelectedSegmentTintColor = UIKit.UIColor.Red;
    }
#endif
}
