codebehind onclick: 

        protected void btnNew_Click(object sender, EventArgs e)
        {
            gridNews.EditIndex = -1;
            ((LinkButton)sender).Visible = false;
            gridNews.InsertItemPosition = InsertItemPosition.FirstItem;
        }



Actual Results:

- the link hides but the insertitemtemplate will not be shown


Expected Results:

- the link hides and the insertitemtemplate appears after postback

How often does this happen? 

 - always
