Thanks for your support,
I am able to render controls inside grid using template but properties binding is not working.
Here is my sample code
<e-column field='OrderDate' headerText='Section' width=150>
<ng-template #editTemplate let-data>
<ng-select [items]="recipeDropDown" bindLabel="displayvalue" bindValue="savedvalue"
placeholder="Select Section">
</ng-select>
</ng-template>
</e-column>
