Hi All.

As below attached is my Javascript validation for one of my asp.net developments. I have attached this at file called form.aspx. Then i declared this " btnEnter.Attributes.Add("onClick", "return valInput();")" at the form.aspx.vb.

what else should i declared to call out this function call updatedetails()


thanks
