Short-circuit first data source read with local data?

[Brian Vallelunga]

I have a data source that is used to fetch remote data for a grid. In my specific situation, I already have the first page of data available on the client and would like to short-circuit the data source's first read attempt and supply my local data. All subsequent requests, due to paging, etc, should happen normally, pulling from the remote data endpoint. Is this possible?

The requestStart event looks like it might be the place to intercept the call, but I'm unsure of exactly how to do this.

Thanks

Hi,

This can be achieved by using a custom function for the read operation that passes the local data initially and then uses a remote request. Here is an example that demonstrates this scenario.

Thanks. That is really helpful, though not quite as automatic as I had hoped. Ideally, the data source itself would perform the ajax call, but it doesn't look like there's any support for doing that. This will work for my needs though. I just need to figure out how to streamline this approach for multiple data sources.

Hello again,

An an alternative I can suggest an approach similar to the one that is currently used for the MVC wrappers - create a custom transport that reads the data from the data option if available. I updated the example to demonstrate this appraoch.
