You'll need to post your relevant code. Pressing Enter fires the default submit for the form so you must have a different one defined.

However, you should not rely just on client side validation. You should always validate server side as well because client side can be hacked.

If you are working on server side validation then you need to use validation group for button which need to be similar of validation group assinged to validation control

Either you can do this

C#

this.Form.DefaultButton = this.btnId.UniqueID;

or

Using Javascript:

JavaScript

function clickButton(e, buttonid)
{

  var evt = e ? e : window.event;

  var bt = document.getElementById(buttonid);

  if (bt)
  {
      if (evt.keyCode == 13)
      {
            bt.click();
            return false;
      }
  }
}

In CoeBehind

C#

ContentPage.Attributes.Add("onkeypress", "javascript:return
clickButton(event,'" + btnSearch.ClientID + "');");
