Dear friends,

I have to check the values of feilds,if field value is empty then
i have to give messge like 'Pl.. enter the login name' in use alert message like popup window whenever i click the button.
if all fields entered then it's go to save.
 I tried for this it's working fine to one function, but after checking the fields i called one more function i.e., in VB function, then two functions are not working.

1. javascript fn
<script LANGUAGE="JavaScript">
function valid()
{

if (alertSubmit1() && alertSubmit2())
   {
     document.frmlogin.submit();

   }
}

function alertSubmit1()
{
var str = document.Frmlogin.loginname.value
if (str=="")
{
    alert("Enter your Login ...")
    document.Frmlogin.loginname.focus()
    return false
}
else
{
    return true
}
}
function alertSubmit2()
{
var str1 = document.Frmlogin.passwd.value
if (str1=="")
{
    alert("Enter your password ...")
    document.Frmlogin.passwd.focus()
    return false
}
else
{
    return true
}
}
</script>

2.vb function to save the data

here i given at button
onclick="valid" onserver click="save"

so, here it's saving but not checking the empty fields

please help me here what i have to do..

thanks in advance
I need a step by step, work thru this process...

thank you

Why not use requiredfieldvalidators. They add the Javascript for you. You can also use the validationsummary control to list all errors on the form.

we can use onclick and onserverclick events at the same time?

if it's there please tell me how to do it.
thanks
