Hello Shubha Singh,
The ComboBox filtering is turned off by default. In order filter the values when pasting text via "Ctrl + V", I suggest setting an appropriate filter:
By design, filtering is performed when the keydown event
is fired. When the value is pasted with the mouse, the event is not triggered, that's why the filtering is not working. This scenario is not supported, and I am afraid that there is no feasible workaround that I can offer.
On a side note, in order to be able to work with "Kendo UI Complete" and benefit from our support service, your account must be associated with an active license or a trial. Your applicable commercial license expired on October 16, 2015.
If your company has spare licenses, please ask the license holder to assign your account as a licensed developer, as explained in "How do I assign developers to the purchased licenses?".
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
