//
// Tricks:
// -----------------------------------------------------------------------------
// 1. Set default value, that disappears on focus:
//      "default"=>"http://www.website.com", "on_js_event"=>"onBlur='if(this.value == \"\") this.value = \"http://www.website.com\"; this.style.color=\"#f68d6f\";' onClick='if(this.value==\"http://www.website.com\") this.value=\"\"; this.style.color=\"#000000\";'",
//
// 2. Set uniquie value for uploading image:
//     a) "file_name"=>"img_".((isset($_GET['prfx_mode']) && ($_GET['prfx_mode'] == "add")) ? $dgrid->GetNextId() : $dgrid->GetCurrentId())
//     b) "file_name"=>"img_".((isset($_GET['prfx_mode']) && ($_GET['prfx_mode'] == "add")) ? $dgrid->GetRandomString("10") : $dgrid->GetCurrentId())
//
// 3. Make auto-submition for filtering fileds:
//      "on_js_event"=>"onchange='document.getElementById(\"...prefix..._ff_onSUBMIT_FILTER\").click();'"
//
// 4. Make a field text colored according to condition (in SQL statement):
//      if (product='flooring', CONCAT('<SPAN style=\"background-color:yellow\">',product,'</SPAN>'),product) as ProductColored,
//
// 5. Change the field's data on fly (for "on_item_created" field's attribute):
//      function setColor($field_value){
//        if(strlen($field_value) > 5){
//            return "<font color='red'>".$field_value."</font>";
//        }else{
//            return "<font color='blue'>".$field_value."</font>";        
//        }
//      }
//
// 6. Change the field's type on fly (for "on_item_created" field's attribute):
//      function setColor($field_value, $field_property_type){
//        if(strlen($field_value) > 5){
//            return "<font color='red'>".$field_value."</font>";
//        }else{
//            $field_property_type = "linktoview";
//            return "<font color='blue'>".$field_value."</font>";        
//        }
//      }
//
// 8. Customized filtering: write filter field with empty table name and field: (..."table"=>"", "field"=>"xxx",...)
//    Then use $my_field = isset($_GET['prefix__ff__xxx']) ? $_GET['prefix__ff__xxx'] : "";
//    Use $my_field in SQL SELECT for your own filtering
