I had two list boxes and some buttons.

I am trying to do the button click event by using keyboard shortcut.

That is, suppose if I press F1 key it should perform same as the functionality if I press button1.

Can any please help me how to write the code?

<script type="text/javascript">
    document.onkeydown = CallClickEvent;    
    function CallClickEvent(e)
    {
        keynum = window.event ? event.keyCode : e.which
        
        if(keynum == 112) //F1
            document.getElementById('<%=Button1.ClientID %>').click()
        else if(keynum == 113)//F2
            document.getElementById('<%=Button2.ClientID %>').click()    
        else if(keynum == 114)//F3
            document.getElementById('<%=Button3.ClientID %>').click()    
        else if(keynum == 115)//F4
            document.getElementById('<%=Button4.ClientID %>').click()

Depending on the keys you wish to use, you might be able to do this without writing any code at all, by using Accelerator Keys.

e.g. If you have a 'Down' button then setting the Text property to &Down will cause the button text to display as Down and pressing Alt-D will cause the button to perform it's click method.

Firstly, don't use F1 - the standards say that is for "Help" and it is not a good idea to change key allocations like that - it confuses users.

Secondly, handle the KeyPress event[^] (alphanumeric keys), and check what key is passed to you in the e.KeyChar parameter.
For non-alphabetic keys, handle the KeyDown event[^] instead, and use the e.KeyCode parameter.
