hi,
try like
function ValidateForm()
{
//your validation code
__doPostBack();
}
__doPostBack causes you to postback. And there you can catch the corresponsding event like,
protected void ddlCity_SelectedIndexChanged(object sender, EventArgs e)
{
}, where you can write your custom logic.
Hope this helps you,
Thanks&Regards,
Anil.
