Hello,

I would recommend you to see our API and documentation links below:

https://www.igniteui.com/help/api/2019.1/ui.iggrid

Expand igGrid and click on the feature for which you like to see API details on above link.

https://www.igniteui.com/help/iggrid

You can set value of unbound column while defining column definition as shown below:

headerText: "Promotion Expired Date", key: "PromotionExpDate", dataType: "date", unbound: true, unboundValues:[new Date('4/24/2012'),new Date('8/24/2012'),new Date('6/24/2012'),new Date('7/24/2012'),new Date('9/24/2012'),new Date('10/24/2012'),new Date('11/24/2012')]},

Refer to the sample on the below link:

https://www.igniteui.com/grid/unbound-column You can query the data from the row and column key as shown below:

var date = $(".selector").igGrid("getCellValue", 3, "ShipDate"); 3 is row index and “ShipDate” is column key.

You can set cell value as shown below:

$("#grid").igGridUpdating("setCellValue", 5, "ProductName", "bologna");

You can hide column as shown below:

$(".selector").igGrid("hideColumn", 1);

OR

 $(".selector").igGrid("hideColumn", "ProductID");

I would recommend you to review the API document link for more details.

I hope this helps.
