Hi Souvick,
We would like to inform that the reported issue occurs, because
the control is not loaded initially. SfRangeSlider is loaded after ValueChanged
event, that makes the instance empty. We have modified your sample that tries
to meet your reuirement of getting RangeEnd value in ValueChanged event.
Please find the sample in below link,
Range_Slider_Test.zip
Please let us know if you have any queries.
Regards,
Vignesh V
