Hello Michel,

You can use the _addTransaction() method to add elements to the pendingTransactions array:

ds = $("#grid").data().igGrid.dataSource;

var rowObject = $("#grid").igGrid("findRecordByKey", 4);

ds._addTransaction(rowObject);

or

you can programmatically update a row with the same values using the update method. The method will also create a transaction and updates the UI, so you will find this row in the pendingTransactions array afterwards:

var rowObject = $("#grid").igGrid("findRecordByKey", 4);

$("#grid").igGridUpdating("updateRow", 4, rowObject);

However I must note that I do not see why would you need to do this. If you clarify your scenario we can suggest a better approach if such exists.
