Hi Yi,
So i am assuming you are storing images in different entity and your data grid 2 retrieval from different entity
in the data grid 2
take a custom content column go to custom content column on the grid take a DataView source microflow -> in the microflow retrieve your image by your storing images entity in the xpath constraint your condition & in the range select first and return this object.
Go to DataView take dynamic image inside dataview and select the entity from dataview.
But if you are using same entity on the datagrid 2 & for image storing.Then no issues It stores one image for one object .
Simply just take a custom content column go to custom content take a dynamic image & select your datagrid 2 entity.
Hope you like the answer.
