Hello Karthik,

Thank you for posting in our community.

I assume that the  issue that you are experiencing is that when you have a grouped columns and add a new it is not going to the respective group. If this is the case what I can suggest is handling rowAdded event of the grid. n this event you could rebind the grid in order to ensure that changes arte accepted by the grid. For example:

 $(function () {
   $('#table1').igGrid({
    virtualization: false,
    autoCommit: true,
    autoGenerateColumns: false,
    width: '500px',
    height: '500px',
    columns: [
     { headerText: "Product ID", key: "ProductID", width: "100px", dataType: "number" },
     { headerText: "Units in Stock", key: "UnitsInStock", width: "150px", dataType: "number" },
     { headerText: "Product Description", key: "ProductDescription", width: "150px", dataType: "string" },
     { headerText: "htmlColumn", key: "htmlColumn", width: "100px", dataType: "string", unbound: true, unboundValues: ["<table><tr><td>I WILL FAIL</td></tr></table>", "<table><tr><td>I WILL FAIL</td></tr></table>", /*workaround*/"<DIV><p>I WILL NOT FAIL</p></DIV>"] }
    ],
    dataSource: namedData,
    primaryKey: "ProductID",
                features: [
                    {
                        name: "GroupBy"
                    },
     {
     name: "Updating",
     rowAdded: function(evt, ui){ 
     $('#table1').igGrid("dataBind");
     }
     }
                ]
            });
        });

I am attaching a small sample illustrating my suggestion for your reference.

If this is not the behavior that you are experiencing could you please modify my sample and send it back to me. Also, some clarifications are going to be highly appreciated and will help me identify the issue and investigate further.

I also checked the development issue mentioned in the referenced thread and I can confirm it is resolved in the latest versions of IgniteUI - 14.1, 14.2 and 15.1.

I hope you find this information helpful.

Please let me know if you need any further assistance with this matter.
