Hi,
Thank you for your interest in Syncfusion Products.
I am afraid I'm not able to reproduce the reported issue, could you please refer the following simple sample.
http://websamples.syncfusion.com/samples/Tools.Windows/F76094/main.htmIf I am missing anything, could you send us a sample/video file, so that could work out in depth and provide you a solution?
Please let me know if any concern.
