How to Control button event in Web Forms when user press Enter button

How to Control button event in Web Forms when user press Enter button


Suppose you have more then one button (three button named: btnFirstButton,btnSecondButton,btnThirdButton) in your web page and after enter button press

First button called.

If you want some particular button should called after enter button press then you can do one this after come out from some control (textbox) you can call one JavaScript function

In textbox onkeypress client side (onkeypress="return OnLevelBlur(event);).


<asp:textbox id="txtbox1" Runat="server" MaxLength="10" onkeypress="return OnLevelBlur(event);">


JavaScript Function


function OnLevelBlur(e)


char = String.fromCharCode(e.keyCode);


if (xCode == 13)


document.all["btnFirstButton"].disabled="false"; document.all["btnSecondButton"].disabled="false"; document.Form1.txtbox1.focus();




How it’s Work


Basically you catch Enter button events and put the condition that if enter button pressed then disable btnFirstButton  and btnSecondButton  then automatically btnThirdButton click event will fire and after server trip  that two buttons btnFirstButton and btnSecondButton will active again.




You are disabling some button which you don’t want to click after enter button.
