Hello @kevalgw,

While there is no built-in property in the grid for a cell editing default value, your requirement could easily be achieved with the methods exposed by the IgxGridComponent API.

The cellEdit event of the grid could be handled in order to check whether the new value of the cell, which could be accessed from the event arguments’ newValue property, is equal to a null value for the corresponding data type. For example, for a ‘string’ that would be ‘’, for a number – 0, for a Date – null, etc.
Then, the specific default value for the particular column has to be set to the currently edited cell’s editValue and the event.newValue properties.
The cell could be retrieved with the help of the getCellByKey method of the grid.
How the default values are determined would depend on your own application logic. In this sample app I prepared for you, they are stored in a Map, for instance. Please, check it out.
