Hi,
igCombo in editable mode option does not take any action when back space is pressed.
In a similar manner how we can restrict the user from selecting the text and deleting it. We are using 2013.2 version
Thanks,

Hello Kiran,
I believe that you need to set the mode of the control to 'readonly' or 'readonlylist', depending on your scenario.
You could take a look at this option here:

Please feel free to let me know if a question about our tool set comes up on your mind.
