Hi David Ching,
We are always doing our best to design our controls as similar as possible to the standard ones. However, in some cases this is not possible. While the standard controls are built using the internal mechanisms of the OS, ours are built on an external framework and sometimes it is very difficult to implement exactly the same behavior. At least, not at a reasonable price.
Still, we consider your suggestion as a feature request and it has been logged in our issue tracker. If we receive other similar requests, we will escalate the implementation of this feature. I have updated your Telerik points for pointing this shortcoming out.
Thank you once again for your response - we are always happy to review our customer's suggestions, because they help us make our controls better.
the Telerik team
