image/imagebutton client validation

[ganesh kolappan]

Hi

is there any way i can call a clientside function for validation onClick of
a Image or imagebutton?
Right now my image or imagebutton is submitting to the server, even it
return false from the clientside function.

my sample code has,
..aspx code:
-------------
function validateme()
{
if ((document.Form1.pwdOldPwd.value != "") ||
(document.Form1.pwdNewPwd.value != "") || (document.Form1.pwdRenterPwd.value
!= ""))
{
if (document.Form1.pwdOldPwd.value == "")
{
htlOldPwd.innerText = "Old Password Required";
document.Form1.pwdOldPwd.focus();
return false;
}
else
htlNewPwd.innerText = " ";
}
else
htlNewPwd.innerText = " ";

return true;
}

<input type="image" id="imgSubmit" src="images/bt_changepassword.gif"
runat="server" onServerClick = "submitme">

codebehind:
--------------
'imgSubmit.Attributes.Add("onClick", "if ( validateme() ) ")

Any ideas??

Thanks

Have you looked at client-side customvalidators?
