Hi Sunil, 
 
Greetings from Syncfusion support. 
 
We are not able to clearly understand your requirement from the provided information. Do you wish to set custom data source for the default edit dropdown in Grid? If so, you can achieve it using the cell edit params property of the Grid columns and we have already documented this requirement in our online help site. So please check the below documentation links for more details on this, 
 
Documentation: https://ej2.syncfusion.com/angular/documentation/grid/how-to/provide-custom-data-source-and-enabling-filtering-to-drop-down-list/ 
                               https://ej2.syncfusion.com/angular/documentation/grid/edit/#cell-edit-type-and-its-params 
 
If this is not your requirement then please elaborate on it with pictorial representation(if possible) based on which we will check and provide the further details. 
 
Let us know if you have any concerns.
