You have to change your regex pattern. Try to replace the last part (\.\d{1,2})? with (\.)?(\d{1,2})?. This means that the . can be set without having to enter the other two digits. You can play around with your regex pattern on regex101.com.

You can use below code into your Angular 4

    <input class="k-textbox" format="{0:c2}"  type="number" step="0.01" onkeydown="return event.keyCode !== 69">
