Question

I have a HTML textbox, I restrict from special characters being entered. But when I paste using Ctrl + V the validation doesn’t fire.

As your question is tagged with jquery, you can bind also to the paste event. In this case, use the method .bind() to attach the same handler for multiple events (whitespace-separated):

$('#someElement').bind('keydown paste', function() {
    // run some code when pasting or on keydown
});
