We have implemented custom timeline intervals for radtimeline which was working fine with earlier version of Telerik framework(2019) but after the upgrade to latest(R3 2022 SP1) Telerik framework, with custom intervals the timeline is not loading when customization is removed it works fine(default timeline intervals).

Is there any change with new framework we should be considering?

We are currently testing out the Telerik Upgrade with Demo version of the framework(R3 2022 SP1). Could this be an issue?

My guess would be that the upgraded Telerik version is NoXaml. In that case the following article will be useful: https://docs.telerik.com/devtools/wpf/common-information/troubleshooting/invisible-controls. Can you try it and tell me if it helps?

Hello Martin,
Yes we are using NoXaml. Thanks for the article.

We have checked as per the article and observed all referenced dlls and added .Xaml files have the resources merged in App.xaml file. We have just replaced earlier version referenced dlls and .xaml files with newer version as part of our migration. We are not implementing any styling on RadTimelineInterval, we are just overriding the IntervalBase  class. 

What we observed is that overridden methods of Intervalbase class are executing(by this we assume the control is actually not missing) but they are executing for eternity my entire timeline display period is 1 year.(IncrementByInterval method of Intervalbase class is an example of that overridden method).

Can you show me the custom interval implementation? If the range is too big and the increment is too small, there could be a huge number of elements which may hit the performance. However, if that was working previously, then maybe something that interacts with your scenario is modified in the control during the last 3 years.

No answers yet. Maybe you can help?
