Add Styling to row/cell on igGrid based on Data


I have a grid with data. I also have a button called 'Validate'. I'm trying to implement a logic such that when I click on the validate button, it goes through all the row data and highlights the row based on the data it contains (For Eg: Highlight the row if the data on a column is missing). I have a function like this, but the row doesn't seem to get highlighted. Please help.

$("#validate").on('igbuttonclick', function (e)
var rows = grid.igGrid("allRows");
var dataField1,dataField2;
$.each(rows, function (index, row) {
rowId = $(row).attr("data-id")
dataField1 = grid.igGrid("getCellValue", rowId, "DataField1");
if (dataField1 == "Val1")
dataField2=grid.igGrid("getCellValue", rowId, "DataField2");
if ( dataField2== "")
$("#invGrid").igGrid("cellById", rowId, "DataField2").addClass("errorHighlight");

Here, I've tried a cell highlight which is jot working. A row highlight will also help me.

    Hello Guruprasad,


    Thank you for posting in our forum.


    You could iterate over the rows and cells of the grid in the validation button’s “click” event handler. Write a filter function to return “true” or “false” if the cell passes the conditions you want. Then add the necessary CSS to highlight the invalid rows. See the code sample I provided below:


    <!DOCTYPE html>
        <script src=""></script>
        <script src=""></script>
        <script src=""></script>
        <script src=""></script>
        <script src=""></script>
        <link href="" rel="stylesheet">
        <link href="" rel="stylesheet">
                background-color: red;
            tr.warning td.ui-state-hover,
            tr.warning td.ui-state-active
        <table id="grid"></table>
        <div style="text-align:center; margin: 20px auto">
            <input type="button" value="Validate" class="btn">

                                //checking each cell with the validating function
                                for (var j = 0; j < currentRow.cells.length; j++){
                                    var currentRowCell = currentRow.cells[j];
                                        //adding the warning CSS

                            persist: true,
                            activation: true
            //The validating function
            function isInvalid(text){
                 return (text === "\xa0" || text === "" || text === " ") ? true : false;
            $(".btn").on('click', function(){
                var rowsArray = $("#grid").igGrid("allRows");
                //iterating over each row of the grid
                for (var i = 0; i < rowsArray.length; i++){
                    var currentRow = rowsArray[i];
                    //iterating over the current row's cells
                    for (var j = 0; j < currentRow.cells.length; j++){
                        var currentRowCell = currentRow.cells[j];


    Note that iterating over a very large dataSource could be resource consuming and slow down the browser’s performance. For such cases I suggest that you use the igValidator control and validate cells during editing.
