Solution 1

Remove foreach block

protected void DataList4_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "lnkhead")
        {
            LinkButton lnk = (LinkButton)e.CommandSource;            
            Label lbl = (Label)e.Item.FindControl("lblhead");
            lbl.Visible = true;
            lnk.Visible = false;
           
        }
    }

Label lbl = (Label)item.FindControl("lblhead");
this line does not works...bcoz it takes items not item after (Label)
