Hello Jose,

In order to achieve your requirement a template column`s option could be used. Since it is applicable to a column, not a row my suggestion is to create something like a generic conditional template applicable for all columns. This approach can help you achieve something similar to row template which afterwards could be used as a basis for the flashing row color. In this template a particular classes will be applied for particular rows (it could be applied to all the rows as well). Afterwards, at some point(in my sample on a button click) all the rows with a particular class could be referenced by this class and manipulated as in the jsfiddle sampel that you provided. For example:

<script id="colTmpl" type="text/template">
  {{if ${ProductID} % 2 == 0 }} 
  <span class='blinkYellow background-color-yellow'>${key}</span>
  {{else}}
  <font color='red'>${key}</font>
  {{/if}}
 </script>
......
 $(function () {
           $("#grid").igGrid({
               columns: [
                    { headerText: "Product ID", key: "ProductID", dataType: "number", template: $("#colTmpl" ).html().replace(/key/g, 'ProductID') },
                    { headerText: "Product Name", key: "Name", dataType: "string", template: $("#colTmpl" ).html().replace(/key/g, 'Name')  },
                    { headerText: "Product Number", key: "ProductNumber", dataType: "string", template: $("#colTmpl" ).html().replace(/key/g, 'ProductNumber') },
     { headerText: "Avalibility", key: "Avalibility", dataType: "number", template: $("#colTmpl" ).html().replace(/key/g, 'Avalibility') },
                    { headerText: "Product Status", key: "ProductStatus", dataType: "string", template: $("#colTmpl" ).html().replace(/key/g, 'ProductStatus')}
                ],
      primaryKey: "ProductID",
               dataSource: products,
       autoCommit : true,
      features:[
       {
                    name: "RowSelectors",
     enableCheckBoxes: true
                },
    {
     name: "Selection",
     //mode: "cell",
      activation : false
    }
      ]
           });
     $("#blink").click(function(){
   setInterval(findYellow,1000);  
     })
     function findYellow(){ 
    $("span.blinkYellow").each(function(){ 
    $(this).toggleClass("background-color-yellow");
   })
  }
       });

I am attaching a small sample for your reference. In this small application I am creating a generic template which applies yellow background color to some rows. There is a button which if clicked starts flickering some rows.

Please test it on your side and let me know if you have any additional questions.
