Hi Alexander,
Thanks for contacting Syncfusion forum.
Based on your query we suspect that you need to store the country id value and need to display the ShipCountry name. To achieve this requirement we need to use the foreignKey column.
Using foreignKeyColumn we can able to display the string data in the dropdown and store the number values in the grid datasource. For foreignKey column the values that you have defined in the mapping field names should be same, then only the required foreignKeyField’s foreignKeyValue value will be shown in that column.
For more information please refer the below demo and document link
In this you also mentioned that foreignKey column is not working fine at your end. So, please share the following details,
1. Complete grid rendering code
2. Video demonstration of your requirement
3. If possible, share issue reproducing sample
Please get back to us, if you need any further assistance.
Regards,
Thiyagu S
