Hi Ashimaz,
Greetings from Syncfusion support.
We would like to inform you that, we don’t have inbuilt support to refresh the data source in custom adaptor. We have considered this as a feature and logged a feature task “Data reloading support in CustomAdaptor” for this requirement. We have planned to implement this and include this feature in any of our upcoming releases.
To make it count, please cast your vote. We will prioritize the features based on the demands of each release. If you have more specifications / suggestions on the request for the feature, you can add it to the portal as a comment.
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
Please get back to us if you need further assistance.
Regards,
Sevvandhi N
